FAQ

Longitudinal Water Blocking vs. Lateral Water Blocking?

How Do Water-Blocking Cables Work?

Flame Retardant Cables VS Fire Resistant Cables?

What is the validity period for the offer of cable?

Armored vs. Unarmored Cables?

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.

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.

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 operating temperature of the cable?

The operating temperature of a cable is determined by the insulation and sheathing material. PVC has a range of -15°C to 70°C, XLPE can reach up to 90°C, while silicone rubber can handle temperatures from -60°C to 180°C.
