XLPE/PVC Concentric Cable
Concentric Cable Construction and materials
Construction and materials concentric cables XLPE/PVC:
Conductor central: copper, aluminium alloy.
insulating layer: XLPE, PVC.
Concentric wire: copper, aluminium alloy
Funda: XLPE, PVC, etc.
The construction and material selection of concentric cables generally depends on the application environment, the voltage level and the relevant technical standards and specification requirements. It is designed to ensure reliable performance, durability and safety in a variety of electrical installations and power distribution systems.
