分束：即是动力电缆与信号电缆分束。

分层：电缆扎在电缆托架上方，一般较长较粗的在下层。

电缆扎在电缆托架下方，一般较长较粗的在上层。

分支：分清径直走向的电缆与转弯的电缆，避免过多的分支。

尽量将分叉处放于隐蔽处。

4.1.1 Cable laying must be divided into layer, splitter and branch.
Splitter: shelf drives cable and signal cable
layer ：Cable tied above cable tray, in general longer and thicker cable laying below.
When cable is bunched under the cable tray, longer and thicker cable is laid on top.
Branch: make it clear that straight cable and flexible cable, avoid overmuch embranchment. Try best to put embranchment in secluded place.
4.1.2电缆拉敷前，应检查线路上所有支承件、贯通件、安装件有无遗漏，有无锐边和毛刺，焊接是否牢靠，是否均已涂有防锈漆及完工漆。

电缆开始拉敷后，在敷设线路上及附近，尽可能避免进行气割和焊接，以免灼伤电缆，否则应有临时防护措施。

4.1.2 before cable laying ,check all supporters ,cable coaming and installations in the line in afraid of missing ,sharp side and burr, check the fastness of the welding and if all rust-resistance and finished painting have been finished .when cable laying start , make sure avoid gas cutting and welding working on the way to cable laying and nearby that may burn the cable ,otherwise, some temporary protecting methods should be used .
4.1.3电缆拉敷前，应仔细核对电缆代号、规格、长度、起终点设备名称和位置以及中间停止点,它们与电缆清册和图纸是否相符，并检查电缆有否损伤。

电缆拉敷时，应使电缆沿着已检查合格的支承件、贯通件的敷设线路方向连续均匀地移动，不得强力硬拖，以免损伤电缆。

4.1.3 Before cable laying, please check the code name , specification ,length ,name of the starting and terminate equipment and middle stop point carefully to see if they accord with the cable manual and the drawing and if they get hurt. When cable laying, the cable should move continuous and even along the eligible supporters, cable coaming and directions, pull by force is not allowed for the reason of hurting the cable.
4.1.4不同护套的电缆混合拉敷时，应特别注意防止电缆相互磨擦而损伤其护套层。

每根电缆拉敷完毕后，均需把电缆理齐整平，校对长度，并把到位电缆或下一步再拉敷的电缆圈好，挂在设备附近。

不得-将电缆随地乱抛，任意踩踏。

4.1.4 When laying the cable with different sleeves, pay more attention to cable friction that may hurt the cable sleeves. After every single cable is finished, we must make cable tidy, check the length and put the cable which will be used next step nearby the equipment .throwing the cable anywhere and trampling are not allowed.

When hidden Laying Backboneless cable, make sure it is convenient for seal plate to start on the path of laying. When embranchment junction box of all cable paths use hidden installation, make sure it is convenient for seal plate to start and have endurable indication. Not only we shouldn’t lay cable through thermal insulation and Sound proof insulation but also should not
paint heat preserve material such as paint and foam. Cable of Refrigerating chamber, boiler room etc all should lay in use of open wire, cable in accommodation should try best to use of hidden installation. If cable in accommodation use open wire, it could protect cable with fire retardant Plastic groove.
4.2.2应防止机械损伤
尽量避免在货舱、贮藏室、甲板上、舱底花钢板下等易受机械损伤的场所敷设电缆，若无法避免时，则货舱、贮藏室、甲板上需设置电缆护罩或电缆管加以防护舱底钢板下穿金属电缆管。

货舱和甲板上的电缆护罩厚度，一般不应小于3mm，以保证足够强度。

尽量避免在可动或可拆的部位敷设电缆，以免活动件移动或拆装时损伤电缆，无法避免时装可拆接头。

The cable should avoid throughing the place of flammability, explode, causticity gas (such as oxygen room, painting room, secondary cell room, bunker, magazine and so on). Some required lighting cable should be laid in the metal pipe. When cable through bulkheads, keep its seal function to prevent the innocuousness gas from coming into other tanks (these tank ’s lighting lamps don ’t use cable sleeves).
Cable with different allowed working temperatures should not lay together, when they have to, all of the cable in the same splitter’s allowed working temperature is the lowest allowed temperature in the splitter.

也可以用满足A-60要求的模块填满模块框做穿舱件。

When tank requires SOLAS definition A-60, fire resistance grade, its cable fire resistance stuffing frame is installed according to the drawing below, but rock wool according to outfitting drawing. If it is convenient to water fire resistance stuffing, the pour hole is not necessary. The thickness of stuffing and sealing should satisfy the demands of drawing. One of the sides should have heat insulation and burn hinder layer. Also module satisfies the demands of A-60 could be used filling in module frame as cable coaming.

5.1 紧固的一般要求
5.1 demands of tightness
5.1.1电缆紧固后不应有任何松动，不应损伤电缆，线路应力求平直整齐。

扎带尼龙扎带紧固扣后距锁扣或搭口5～6mm处将多余部分切除，力求整齐。

扎紧金属扎带后，把长出来部分卷起来。

5.1.1 After cable tightness, any loose is not allowed, dandify cable is not allowed either. Try to make circuitry straight and tidy. After stabbing and nylon stabbing are tightened, 5-6mm between the buttons and stabbing should be cut, try to make it tidy. After stabbing has been tightened, roll up the longer part.
5.1.2电缆分层分束敷设,细小电缆（细小电缆定义见第二节）扎成电缆束其宽度不宜大于150mm。

设计初期电缆选型要留够余量（一般用额定电流除以0.8），使得电缆多于两层敷设时有合适的载流系数，防止产生电缆过热问题。

5.1.2 Cable laying is divided into layer and splitter, tiny cable (definition see the second section) is bunched into cable; its width must less than 150mm. At the beginning of design, undertake current of the cable should big enough (rated current divide 0.8) that when cable is laid more than two layers have appropriate carry current coefficient, avoiding over heat problem.
5.1.3电缆托架撑脚间距S：当其宽度W不大于500mm时，S不大于1500mm；当其宽度W 大于500mm时，S不大于1200mm.
5.1.3 the distance between cable tray supporter legs is S: when width W less than 500mm, S less than 1500mm; when W more than 500mm, S should less than 1200mm.
5.1.4除光缆外,对于船舶推进和操纵等重要的控制、监测和安全系统的信号电缆，不能与电力或照明电缆在同一束内紧固,分束间距不小于50mm。

5.1.4 Apart from light cable, as for the signal cable of thrust and operates, control, inspection and security system can’t be tightened with power or lighting cable in one splitter, the distance of splitter should more than 50 mm.
5.1.5在扁钢支架上紧固电缆，应使最底层的所有电缆与扁钢接触。

电缆根数足够多时，尽量使最底层的电缆宽度稍大于扁钢的宽度，以避免扎带割伤电缆。

见下图
5.1.5 When tighten the cable on flat steel bracket, try to make cable in the bottom contact with flat steel. If the number of the cable is enough, try to make the width of the cable in the bottom bigger than flat steel in order to avoid stabbing hurting the cable. See drawing below.。
