What are the benefits of EPR material?

EPR is widely used as an insulation material for electric cables due to its high dielectric strength, and it also serves as a sheathing material with excellent ozone and weathering resistance. EPR has a wide thermal range, typically spanning from -55°C to 150°C. Unlike other organic rubbers, there is no need to tin the copper conductor to prevent deterioration of the rubber.

What is the operating temperature of the cable?

The operating temperature of a cable is determined by the insulation and sheathing material. PVC has a range of -15°C to 70°C, XLPE can reach up to 90°C, while silicone rubber can handle temperatures from -60°C to 180°C.

What is the minimum order quantity for the product?

The minimum order quantity for low and medium voltage cables is 200 meters, whereas for high voltage cables, it is 2000 meters. Should the order quantity fall below the MOQ, however, if the factory has stock, we can still supply it.

What is the purpose of a metallic shield in MV and HV cables?

Medium and high voltage power cables, typically those in circuits exceeding 2kV, usually feature a shield layer made of copper or aluminum tape. Similar to their use in low voltage cables, metallic wires and tapes are employed to prevent electromagnetic interference. These shields effectively neutralize or significantly diminish the field currents surrounding the conductor or core. The capacitive and inductive charging currents induced under normal operating conditions are subsequently grounded by the metallic screen.
