FAQ

What is the minimum order quantity for the product?
What is the purpose of a metallic shield in MV and HV cables?
What is the service life of cables?
What is the validity period for the offer of cable?
What are the weight limits for different types of packages?
How do you calculate the minimum bending radius of cables?
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.
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 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 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.
How do you calculate the minimum bending radius of cables?
The bend radius refers to the curved shape in which an electrical cable can be bent or curved without sustaining damage. To determine the minimum bend radius for cables, apply the following formula: Minimum Bend Radius = Cable Outer Diameter×Cable Multiplier. For example, if the outer diameter of a cable is 20mm, its minimum bending radius would be 20mm×6 = 120mm. Conversely, if an armored cable has an outer diameter of 30mm, its minimum bending radius would be 30mm×12 = 360mm.
