High performance power accessories product inventory
With the continuous progress of science and technology and the rapid development of industry, power accessories products play a vital role in modern society. Whether it is power transmission, substation construction or plant equipment operation, high-performance power accessories are one of the key factors to ensure the safe, stable and efficient operation of the power supply system. The purpose of this article is to take stock of some high-performance power accessories products for readers, and provide purchase advice to help readers choose the most suitable for their needs. First, high voltage cable As an important part of power transmission, high voltage cable plays an important role in the stability of power system. When selecting high voltage cables, it is necessary to consider factors such as conductive materials, insulating materials, and outer layer materials. Generally speaking, copper conductors have good electrical conductivity and oxidation resistance, and are suitable for long-distance transmission; Insulation materials should be selected with good durability and high temperature resistance, such as polyethylene or rubber; The material of the outer layer shall be waterproof, corrosion-resistant and pressure-resistant. When purchasing, you are advised to select the right specifications, materials, and brands according to the requirements of the specific scenario. Two, circuit breaker High performance circuit breaker is an important equipment to ensure the safe operation of power system. Common circuit breakers include air circuit breakers, vacuum circuit breakers and SF6 circuit breakers. Air circuit breaker is suitable for low voltage system, with large capacity, low cost characteristics; The vacuum circuit breaker is suitable for medium voltage system and has the characteristics of strong interrupt ability and reliable operation. SF6 circuit breakers are suitable for high voltage systems, with high power failure capacity and good arc extinguishing characteristics. When purchasing circuit breakers, it is necessary to comprehensively consider the voltage…
