Product Description

Copper Condcutor insulated DC Cathodic Protection Cable

1. Applications
The cathodic protection cable mainly used for impressed current cathodic protection system.
It has excellent electrical properties, mechanical behavior, heat aging property, resistance to environment stress and chemical corrosion resistance ability, very low water absorption and simple structure ,easy to use and not retain by laying fall etc.
The products is equivalent to the national standards GB16702 and the national petroleum company of Saudi Arabia 17-SAMSS-017<Impressed current cathodic protection cable procurement norms>of our corporate standard to organize production. The company also may require the user or by other standards, designing and manufacturing some special functions of cathodic protection cable.
