铜包钢线(CCS)简介

铜包钢线(CCS)简介

铜包钢线(CCS)简介一,铜包钢线结构和性能铜包钢线(Copper clad steel wire,简称CCS线)是国际上近几十年开发的新产品,国外发达国家已广泛使用。

在中国,大量使用铜包钢线还是近几年的事。

铜包钢线(CCS)属双金属复合线材,它是利用两种金属各自的优点,通过特殊的生产工艺而制成的。

早在上个世纪30年代,最早由德国发明,随后在美国、英国、法国等先进国家迅速推广。

并广泛地应用于各种领域,包括电力传输系统。

1968年铜包铝、铜包钢线被应用在CATV电缆上。

1,铜包钢线结构铜包钢线是以钢线为芯体,在其表面上覆一层铜的复合线材,如图1所示结构。

铜包钢线在性能上兼备了钢的高强度、耐高温软化的机械性能和铜导电率高、接触电阻小的电性能,因而具有传导效率高,材料成本低,抗拉断力大,质量轻,耐磨损的特点。

它在电缆行业中可代替铜导体作为分配线或在通信业中用作电话用户线、高频传输电缆的导体。

图1,铜包钢线结构视图铜包钢线由钢芯线和紧密包覆其外的铜层构成,铜包钢线按导电率可分为21%IACS、30%IACS和40%IACS(IACS国际退火铜标准导电率)三种。

铜包钢线按力学性能(退火状态)可分为软态(A)、硬态(HS)和超硬态(EHS)。

铜包钢线经过深加工,还可加工成镀银铜包钢线、镀锡铜包钢或镀铅合金铜包钢线。

一般CATV电缆采用30%的软态铜包钢作内导体。

铜包钢线的表示方法:铜包钢线执行的标准:铜包钢线执行的标准有:ASTM B 22704-04《拉制硬态铜包钢线》、ASTM B 910/B910M-04《退火态铜包钢线》、ASTM B 869-04《CATV 同轴电缆用铜包钢线》和ASTM B 452-02《电子产品用铜包钢线》。

也有按GB12269-91、YD/T 722-94、BS4087-1989、ASTM B227-93、ASTM B3452-93等标准生产。

2,铜包钢线性能特点铜包钢线将钢的高强度与铜的高导电性和抗腐蚀性相结合,使它已成为通信、电力、电子行业中的理想导线。

ASTM B452-2002 铜包钢线标准规范(英文)

ASTM B452-2002 铜包钢线标准规范(英文)

Designation:B452–02Standard Specification forCopper-Clad Steel Wire for Electronic Application1This standard is issued under thefixed designation B452;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1This specification covers bare round copper-clad steel wire for electronic application.1.2Four classes of copper-clad steel wire are covered as follows:1.2.1Class30HS—Nominal30%conductivity hard-drawn,1.2.2Class30A—Nominal30%conductivity annealed, 1.2.3Class40HS—Nominal40%conductivity hard-drawn,and1.2.4Class40A—Nominal40%conductivity annealed. 1.3The values stated in inch-pound units are to be regarded as the standard.The values given in parentheses are in SI units.2.Referenced Documents2.1The following documents of the issue in effect on the date of material purchase form a part of this specification to the extent referenced herein:2.2ASTM Standards:B193Test Method for Resistivity of Electrical Conductor Materials2B258Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors22.3National Institute of Standards and Technology: NBS Handbook100—Copper Wire Tables33.Ordering Information3.1Orders for material under this specification shall include the following information:3.1.1Quantity of each size and class,3.1.2Wire size,diameter in inches(see5.3and Table1), 3.1.3Class of wire(see1.2and Table1),3.1.4Packaging and shipping(Section10),3.1.5If inspection is required(see6.3.3),and3.1.6Place of inspection(see6.1).4.Material4.1The wire shall consist of a core of homogeneous open-hearth,electric-furnace,or basic-oxygen steel with a continuous outer cladding of copper thoroughly bonded to the core throughout and shall be of such quality as to meet the requirements of this specification(Note1).N OTE1—The copper-clad steel wire provides a high-strength conductor for use in wire and cable where greater strength is required and a lower conductivity can be tolerated.At high frequencies the reduced conductiv-ity is less pronounced due to concentration of the current in the outer periphery of the wire.Minimum thickness of6%and10%of the radius for30and40%conductivity material,respectively,has been established to facilitate the inspection of thickness onfine wires.5.General Requirements5.1Tensile Strength and Elongation—The copper-clad steel wire shall conform to the tensile strength and elongation requirements of Table1.For intermediate sizes not listed in Table1,the elongation requirements of the next smaller size shall apply;in the case of tensile strength,the requirements of the next larger size shall apply.5.2Resistivity—The electrical resistivity at a temperature of 20°C shall not exceed the values prescribed in Table2.See Note2for calculating electrical resistance.N OTE2—Relationships which may be useful in connection with the values of electrical resistivity prescribed in this specification are shown in Table3.Resistivity units are based on the International Annealed Copper Standard(IACS)adopted by IEC in1913,which is1⁄58V·mm2/m at20°C for100%conductivity.The value of0.017241V·mm2/m and the value of 0.15328V·g/m2at20°C are respectively the international equivalent of volume and weight resistivity of annealed copper equal to100% conductivity.The latter term means that a copper wire1in.in length and weighing1g would have a resistance of0.15328V.This is equivalent to a resistivity value of875.20V·lb/mile2,which signifies the resistance of a copper wire1mile in length weighing1lb.It is also equivalent,for example,to1.7241µV/cm of length of a copper bar1cm2in cross section.A complete discussion of this subject is contained in NBS Handbook100. The use offive significantfigures in expressing resistivity does not imply the need for greater accuracy of measurement than that specified in Test Method B193.The use offive significantfigures is required for complete reversible conversion from one set of resistivity units to another.5.3Dimensions and Permissible Variations—The wire sizes1This specification is under the jurisdiction of ASTM Committee B01onElectrical Conductors and is the direct responsibility of Subcommittee B01.06onComposite Conductors.Current edition approved April10,2002.Published April2002.Originallypublished as B452–st previous edition B452–93(1998)e1.2Annual Book of ASTM Standards,V ol02.03.3Available from the National Institute of Standards and Technology(NIST),Gaithersburg,MD20899.Copyright©ASTM International,100Barr Harbor Drive,PO Box C700,West Conshohocken,PA19428-2959,United States.shall be expressed as the diameter of the wire in decimal fractions of an inch to the nearest0.0001in.(0.003mm)(Note 3).For diameters under0.0100in.(0.254mm),the wire shall not vary from the specified diameter by more than60.0001in.(0.003mm)and for diameters of0.0100in.(0.254mm)and over,the wire shall not vary from the specified diameter by more than61%,expressed to the nearest0.0001in.(0.003 mm).N OTE3—The values of the wire diameters in Table1are given to the nearest0.0001in.(0.003mm)and correspond to the standard sizes given in Specification B258.The use of gage numbers to specify wire sizes is not recognized in this specification because of the possibility of confusion. An excellent discussion of wire gages and related subjects is contained in NBS Handbook100.5.4Adhesion and Other Defects—The copper-clad steel wire,when tested in accordance with7.4,shall not reveal any seams,pits,slivers,or other imperfection of sufficient magni-tude to indicate inherent defects or imperfections.Examination of the wire at the break with the unaided eye(normal spectacles excepted)shall show no separation of copper from the steel.5.5Joints—Necessary joints in the wire and rods prior to final drawing shall be made in accordance with good commer-cial practice.Thefinished wire shall contain no joints or splices made atfinished size.5.6Finish—The wire shall be free from copper discontinui-ties and all imperfections not consistent with good commercial practice(see7.5).5.7Copper Thickness—The minimum copper thickness due to eccentricity shall be not less than the following:5.7.1The30%conductivity wire shall have a minimum thickness of not less than6%of the wire radius.5.7.2The40%conductivity wire shall have a minimum thickness of not less than10%of the wire radius(see7.6and Note3).6.Inspection6.1General—All tests and inspections shall be made at the place of manufacture unless otherwise agreed upon between the manufacturer and the purchaser at the time of the purchase. The manufacturer shall afford the inspector representing the purchaser all reasonable facilities to satisfy him that theTABLE1Tensile and Elongation RequirementsDiameter Cross-Sectional Area at20°C Tensile Strength,psi(kgf/mm2)Elongation,min.%in10in.(250mm)in.mm cmil in.2mm2Class30HS,min Class30A,min Class40HS,min Class40A,minClass30HS and40HSClass30A and40A0.0720 1.8351800.00407 2.63127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.515 0.0641 1.6341100.00323 2.08127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.515 0.0571 1.4532600.00256 1.65127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.515 0.0508 1.2925800.00203 1.31127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.5150.0453 1.1520500.00161 1.04127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.515 0.0403 1.0216200.001280.823127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.015 0.03590.91212900.001010.653127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.015 0.03200.81310200.0008040.519127000(89.3)50000(35.2)110000(77.3)45000(31.6) 1.0150.02850.7248120.0006380.412127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.015 0.02530.6436400.0005030.324127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.015 0.02260.5745110.0004010.259127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.015 0.02010.5114040.003170.205127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.01790.4553200.0002520.162127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.01590.4042530.0001990.128127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.01420.3612020.0001580.102127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.01260.3201590.0001250.0804127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.0100.01130.2871280.0001000.0647127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.01000.2541000.00007850.0507127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00890.22679.20.00006220.0401127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00800.20364.00.00005030.0324127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00710.18050.40.00003960.025*******(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00630.16039.70.00003120.020*******(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00560.14231.40.00002460.0159127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00500.12725.00.00001960.0127127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.0100.00450.11420.20.00001590.010*******(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00400.10216.00.00001260.00811127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00350.08912.20.000009620.00621127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010 0.00310.0799.610.000007550.00487127000(89.3)55000(38.7)110000(77.3)50000(35.2) 1.010TABLE2Resistivity,max,at20°CClass of Wire V·mm2/m30HS and30A 40HS and40A 0.05862(0.058616) 0.04397(0.043970)material is being furnished in accordance with this specifica-tion(Note4).N OTE4—Cumulative results secured on the product of a single manu-facturer,indicating continued conformance to the criteria,are necessary to ensure an overall product meeting the requirements of this specification. The sample sizes and conformance criteria given for the various charac-teristics are applicable only to lots produced under these conditions. 6.1.1Unless otherwise agreed by the manufacturer and the purchaser,conformance of the wire to the various requirements listed in Section5shall be determined on samples taken from each lot of wire presented for acceptance.6.1.2The manufacturer shall,if requested prior to inspec-tion,certify that all wire in the lot was made under such conditions that the product as a whole conforms to the requirements of this specification as determined by regularly made and recorded tests.6.2Definitions:6.2.1lot—any amount of wire of one class and size pre-sented for acceptance at one time,such amount,however,not to exceed10000lb(4500kg)(Note5).N OTE5—A lot should comprise material taken from a product regularly meeting the requirements of this specification.Inspection of individual lots of less than500lb(230kg)of wire cannot be justified economically. For small lots of500lb(230kg)or less,the purchaser may agree to the manufacturer’s regular inspection of the product as a whole as evidence of acceptability of such small lots.6.2.2sample—a quantity of production units(coils,reels, etc.)selected at random from the lot for the purpose of determining conformance of the lot to the requirements of this specification.6.2.3specimen—a length of wire removed for test purposes from any individual production unit of the sample.6.3Sample Size—The number of production units in a sample(see Note4)shall be as follows:6.3.1For tensile strength,elongation,resistivity,and adhe-sion and other defects,the sample shall consist of four production units.For surfacefinish the sampling shall be in accordance with Table4.From each unit,one test specimen of sufficient length shall be removed for the performance of the required tests.6.3.2For dimensional measurements,the sample shall con-sist of a quantity of production units shown in Table5under heading“First Sample.”6.3.3For packaging inspection(when specified by the purchaser at the time of placing the order),the sample shall consist of a quantity of production units as shown in Table4.7.Test Methods7.1Tensile Strength and Elongation—The tensile strength, expressed in pounds per square inch(or kilograms-force per square millimetre),shall be obtained by dividing the maximum load carried by the specimen during the tension test,by the original cross-sectional area of the specimen.Tensile strength and elongation may be determined simultaneously on the same specimen.7.1.1For Classes30A and40A,the elongation of wire may be determined as the permanent increase in length,expressed in percent of the original length,due to the breaking of the wire in tension,measured between gage marks placed originally10 in.(250mm)apart upon the test specimen(Note6).The elongation of wire shall be determined as described above or by measurements made between the jaws of the testing machine.When the latter method is used,the zero length shall be the distance between the jaws at the start of the tension test when10%of the minimum specified breaking load has been applied and be as near10in.(250mm)as practicable,and the final length shall be the distance between the jaws at the time of rupture.The fracture shall be between gage marks in the case of specimens so marked or between the jaws of the testing machine and not closer than1in.(25mm)to either gage mark or either jaw.N OTE6—It is known that the rate of loading during tension testing affects the performance of the sample to a greater or lesser extent depending upon many factors.In general,tested values of tensile strength are increased and tested values of elongation are reduced with increase of speed of the moving head of the testing machine.In the case of tests on soft or annealed wire,however,the effects of speed of testing are not pronounced.Tests of soft wire made at speeds of moving head which under no-load conditions are not greater than12in./min(300mm/min)do not alter thefinal results of tensile strength and elongation determinations to any practical extent.In the case of hard-drawn wire,these effects are pronounced when the speed of the moving head is excessive.It is suggested that tests be made at speeds of moving head which,under no-load conditions,are not greater than3in./min(76mm/min),but in no case at a speed greater than that at which correct readings can be made.7.1.2For Classes30HS and40HS,the elongation shall be measured by means of an extensometer or other device suitable for measuring elongation in10in.(250mm),and having a vernier reading to0.01in.(0.25mm)attached to the test specimen at a tension load of approximately10%of rated strength.The

comply with the conformance criteria of this section,shall be considered as complying with the requirements of Section 5.Individual production units that fail to meet one or more of the require-ments shall be rejected.Failure of a sample group from a lot to meet one or more of the following criteria shall constitute cause for rejection of the lot.The conformance criteria for each of the prescribed properties given in Section 5are as follows:8.2Tensile Strength and Elongation (for all Classes)—The lot shall be considered conforming,if the values of the four specimens are not less than the appropriate values in Table 1.8.3Resistivity —The electrical resistivity of each of the four specimens shall conform to the requirements of Table 2.Failure to meet these requirements shall constitute failure to meet the resistivity conformance criterion of 5.2.8.4Dimensions —The dimensions of the first sample (Table 4)shall conform to the requirements of 5.3.If there are no failures,the lot shall be considered as conforming to these requirements.If there are failures,but the number of these donot exceed the allowable defect number c 2(Table 5)for the respective number of units in the sample,a second sample equal to n 2shall be taken and the total defects of the n 1+n 2units shall not exceed the allowable defect number c 2.Failure to meet this requirement shall constitute failure to meet the dimensional conformance criterion.8.5Adhesion —Adhesion of the copper cladding to the steel of each of the four specimens shall conform to the require-ments of 5.4.Failure of more than two specimens shall constitute failure to meet the adhesion criterion.If more than two specimens fail to meet the adhesion criterion,four addi-tional specimens from the lot shall be tested,all of which shall conform to the adhesion criterion.However,any individual production unit from which the specimen failed to meet the adhesion criterion shall be rejected.8.6Finish —The finish of the samples taken in accordance with Table 5shall conform to the requirements of 5.6.The number of units in the sample showing surface defects not consistent with commercial practice shall not exceed the allowable defect number c,in Table 5.Failure to meet this requirement shall constitute failure to meet the finish conform-ance criterion.8.7Packaging —Conformance to the packaging require-ments specified by the purchaser shall be determined in accordance with Table 5.The number of units in the sample showing nonconformance to the requirements shall not exceed the allowable defect number c ,in Table 4.Failure to meet this requirement shall constitute failure to meet the packaging conformance criterion.9.Density9.1For the purpose of calculating mass/unit length,cross sections,etc.,the
