FAQ

What is the length tolerance for cables?

What is the service life of cables?

What are the weight limits for different types of packages?

How Do Water-Blocking Cables Work?

What is the operating temperature of the cable?

What is the length tolerance for cables?

The tolerance for the power cable is 0 to +0.5%. For the bare conductor, the tolerance is ±5%.

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 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.

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 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.
