PVC Insulated Power Cable
Product Description
|
Application
With the characteristics of stable performance、advanced technology、broad materials resources、low prices、good flexible and easy to lay and maintain, the polyvinyl chloride insulated power cable is used in fixing lay-up on transmission and distribution electric lines of 50 Hz A.C rated voltage 10 KV or below.
Application properties
- Long term permissible working temperature of cable conductive core is not more than 70℃.
- During short circuit (maximum permanent time is not more than 5 seconds), Temperature of cable conductor is not more than 165℃.
- The difference level of lay-up cable is not restricted. When laying the cable, ambient temperature of laying is not low than 0℃.
- They have a good chemical stability, acid resistance, alkali resistance, salt resistance, oil resistance, solvent resistance and flame retardant properties..
- Light weight, good bending properties and easy to install and maintenance
