FAQ

What are the benefits of EPR material?
Armored vs. Unarmored Cables?
What is the operating temperature of the cable?
How do you calculate the minimum bending radius of cables?
What is the length tolerance for 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.
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 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 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.
What temperature can high-temperature resistant cables reach, and what are their application scenarios?
High-temperature resistant cables are engineered to function within a wide temperature range, spanning from -50°C to +260°C, depending on the cable's specific type and construction. Silicone rubber-insulated cables can withstand temperatures up to 180°C, whereas fluoroplastic insulated cables are designed to endure temperatures as high as 200°C to 260°C over extended periods. They are widely used in steel metallurgy, power, petrochemicals, aerospace, and industrial kilns for power transmission and equipment control in high-heat environments.
