交联电力电缆技术性能
技术性能 Technology property
1、弯曲半径: 1.Bending radius:
单芯电缆允许弯曲半径为20(d+D)±5% Bending radius of single core cable is 20(d+D)±5%
多芯电缆允许弯曲半径为15(d+D)±5% Bending radius of multi-core cable is15(d+D)±5%
D=电缆的实际外径(mm) D=Actual outer diameter of cable sample(mm)
d=导体的实际直径(mm) d=Actual diameter of the conductor(mm)
2、敷设温度: 2.Installation temperature
低于0℃敷设时必须预先加温。 It should be heated where ambient temperature is below 0℃
3、敷设落差: 3.Leverdifference of cable installaton:
电缆敷设不受水平落差限制。 Not restricted by the difference of level along the route.
