High-voltage switchgear, also known as high-voltage switchgear, is mainly used for power generation, transmission, distribution, electrical energy conversion and consumption in the power system as an on-off, control or protection, voltage level in the 3.6kV ~ 550kV electrical products, mainly including high-voltage circuit breakers, high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof distribution devices and high-voltage switchgear and other major categories.
The materials used in the manufacture of high-voltage switchgear cabinet not only include cold-rolled steel plates or angles, zinc-coated or galvanized steel plates, stainless steel plates, but also aluminum plates, mainly a5052p aluminum sheet, which belong to Al-Mg system alloy, the main alloying element is magnesium, and then add a small amount of metal alloy, with forming processing performance, in corrosion resistance and aluminum plates again weldability, used in the manufacture of fuel tanks, oil pipes, as well as transportation vehicles, ship's sheet metal parts, meters, street light brackets and rivets, hardware products, electrical enclosures, etc.
