FAQ

What is the minimum order quantity for the product?

What is the application of Armored vs. Unarmored Cables?

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

What are the weight limits for different types of packages?

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

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 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.

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.

Is a flame-retardant cable also fire resistant?

No. A flame-retardant cable is not the same as a fire-resistant cable. A flame-retardant cable is designed to restrict the spread of fire by inhibiting combustion. Fire-resistant cables, on the other hand, maintain circuit integrity and continue to function for a specified time under defined fire conditions.

What is the application of Armored vs. Unarmored Cables?

Armored cables are suitable for use in hazardous environments, such as underground installations, areas with high moisture levels, and areas prone to mechanical damage. Unarmored cables are suitable for less demanding applications, such as inside walls or other protected locations.
