FAQ From Customers
-
What are high voltage power cables used for?
High-voltage power cables are designed for the transmission of electricity over long distances. They are used in high-voltage transmission lines to deliver electricity from power plants to substations. These cables are engineered to handle high electrical loads, minimize energy loss, and ensure safety in long-distance electrical power transmission. High-voltage cables are typically made with advanced insulation materials to withstand high stress and environmental factors. -
What are the differences between high, medium, and low voltage power cables?
The main difference between high, medium, and low voltage power cables lies in the voltage level and their intended applications. High-voltage cables are used for long-distance power transmission, typically ranging from 1kV to 765kV. Medium voltage cables (1kV to 35kV) are used for power distribution from substations to local areas. Low-voltage cables (up to 1kV) are used in residential, commercial, and industrial buildings for everyday power supply. -
What is the application of low voltage power cables?
Low-voltage power cables are used in residential, commercial, and industrial electrical wiring systems. These cables provide power for lighting, appliances, and smaller equipment within homes, office buildings, and factories. Low-voltage cables are commonly used for internal wiring, electrical circuits, and power distribution within the building. They are designed to carry power safely and efficiently at voltages up to 1kV. -
How are medium voltage power cables used in power distribution?
Medium voltage power cables (1kV to 35kV) are used in power distribution systems to carry electricity from substations to residential neighborhoods, commercial buildings, and industrial complexes. These cables are designed to handle higher loads than low-voltage cables, and they are ideal for situations where energy needs are larger but not as high as transmission-level power. Medium voltage cables provide stable and reliable electrical service to a wide range of users. -
What materials are commonly used in power cables for high, medium, and low voltage systems?
Power cables for high, medium, and low voltage systems are typically made with copper or aluminum conductors for excellent electrical conductivity. The insulation materials include cross-linked polyethylene (XLPE) for high performance and thermoplastic compounds like PVC for standard applications. Sheath layers are typically made of PVC or PE for mechanical protection and weather resistance. The materials are selected based on the voltage rating and the specific environmental and performance requirements of the cable.
