FAQ

What is the application of Armored vs. Unarmored Cables?

How Do Water-Blocking Cables Work?

Is a flame-retardant cable also fire resistant?

Longitudinal Water Blocking vs. Lateral Water Blocking?

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

What is the validity period for the offer of cable?

Typically, the offer is valid for 7 to 30 days, and the price will be adjusted according to the cost of raw materials and the exchange rate.

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.

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

The validity period for most cold shrink cable accessories is typically 3 years from the date of manufacture, provided they are stored under recommended conditions. These conditions usually include controlled humidity and temperature ranges.

Why do cable prices vary significantly among suppliers within the same region?

Cable prices vary due to differences in supplier strategies, competition, raw materials, and production processes, as well as after-sales services, including installation, equipment, and ongoing support.
