Transformers are one of the key electrical equipment in power distribution stations. Oil-immersed transformers are widely used because they have good dielectric strength, strong heat transfer performance and low construction costs. They can solve the problem of heat pipe heat dissipation in large sp

I. Causes and hazards of moisture in cabinets(1) Causes of moisture in the cabinet1) The environment is closed. The ring main unit or switch room itself is a closed environment. Due to poor ventilation conditions, it is easy to accumulate moisture and generate condensation. In order to reduce the oc

Basic definitionHigh-voltage switchgear refers to electrical products used in power generation, transmission, distribution, power conversion and consumption in power systems to perform switching, control or protection functions. The voltage level is between 3.6kV and 550kV. It mainly includes high-v

The transmission voltage of high-voltage transmission lines is mostly above 10,000 volts, and the voltage of some lines is as high as 100,000 volts or 500,000 volts. If you want to insulate such lines, the thickness of the insulation layer of ordinary wires is far from enough. We Normally, the volta
