交聯(lián)電力電纜技術(shù)性能
技術(shù)性能 Technology property
1、彎曲半徑: 1.Bending radius:
單芯電纜允許彎曲半徑為20(d+D)±5% Bending radius of single core cable is 20(d+D)±5%
多芯電纜允許彎曲半徑為15(d+D)±5% Bending radius of multi-core cable is15(d+D)±5%
D=電纜的實(shí)際外徑(mm) D=Actual outer diameter of cable sample(mm)
d=導(dǎo)體的實(shí)際直徑(mm) d=Actual diameter of the conductor(mm)
2、敷設(shè)溫度: 2.Installation temperature
低于0℃敷設(shè)時(shí)必須預(yù)先加溫。 It should be heated where ambient temperature is below 0℃
3、敷設(shè)落差: 3.Leverdifference of cable installaton:
電纜敷設(shè)不受水平落差限制。 Not restricted by the difference of level along the route.
