FAQ

What is the operating temperature of the cable?

Armored vs. Unarmored Cables?

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

What temperature can high-temperature resistant cables reach, and what are their application scenarios?

How long is the validity period of cold shrink cable accessories?

Armored vs. Unarmored Cables?

Armored cables are ideal for direct burial and laying underground, offering protection against environmental factors. Unarmored cables are unsuitable for burial or use in other challenging applications and installations.

What are the weight limits for different types of packages?

The weight limit for a wooden drum or steel wooden is 5,000 kg, and for a steel drum, it is 10,000 kg.

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 service life of cables?

The design life of power cables is typically 20 to 30 years; however, this can vary significantly based on factors such as installation, environmental conditions, and the quality of the cable.

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.
