FAQ

What are the weight limits for different types of packages?

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

Armored vs. Unarmored Cables?

How do you calculate the minimum bending radius of cables?

What is the service life of cables?

Flame Retardant Cables VS Fire Resistant Cables?

Both types of cables are crucial in enhancing the likelihood of escape and survival in the event of a fire and are often confused with one another. However, there is a fundamental distinction between flame retardant cables and fire resistant cables. Flame retardant cables are engineered to inhibit the spread of fire to adjacent areas. On the other hand, fire resistant cables are specifically designed to preserve circuit integrity and ensure functionality during a fire, under specified conditions, aiding both evacuees and firefighters.

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 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 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.

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.
