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. Ⅱ,Application properties 1,Long term permissible working temperature of cable conductive core is not more than 70°C. 2,During short circuit (maximum permanent time is not more than 5 seconds),Temperature of cable conductor is not more than 165°C. 3,The difference level of lay-up cable is not restricted. When laying the cable, temperature of laying is not low than 0°C. 4,They have a good chemical stability, acid resistance, alkali resistance, salt resistance, oil resistance, solvent resistance and flame retardant properties.. 5,Light weight, good bending properties and easy to install and maintenance:
