电流额定值是基于导体允许最高工作温度为105℃和25℃的环境温度中,并假定在空气中自由分离的单线。
周围温度
when you choose the cable ampacity, please take note/电缆载流量选用时注意事项：
Selection of electric wire and cable ampacity (through the work of cable conductor), must consider the use of the environment, whether the highest temperature of cable laying and the soil resistance (intensive
influence of moisture migration) impact. Laying environment is very complex, need according to the specific circumstances of assumed conditions, calculation of the ampacity multiplied by a correction coefficient K,modified structure for reference only.
选用电线电缆载流量（通过导体的工作电流）时,必须考虑使用环境最高温度、电缆是否密集敷设及土壤热阻（水份迁移的影响）等因素的影响。敷设环境是非常复杂的,需根据具体情况,对假设条件下计算的载流量乘以修正系数K,修正结构仅供参考。
Correction factor for ambient temperature 根据周围温度的校正系数
Ta:Ambient temp
[注] Please note that ampacity may be reduced by ampacity of terminals or connectore. 请注意电流值有时会受接头或压着端子等的限制。页码/Page 1/2
