GIS high voltage switch is a widely used distribution device in industry. In recent years, with the improvement of the enterprise's independent development capability and the absorption of advanced technology at home and abroad, the technology of China's high-voltage switch industry is becoming increasingly mature, and the high-voltage switch products produced meet the essential requirements of users. Aluminum alloy high voltage switch shell material mainly are 5052 aluminum plate, 5083 alloy aluminum plate, and for 1060, 3003, 5754 alloy aluminum plate relatively is less.
Introduction to aluminum plate for high voltage switch GIS shell
5052 aluminum plate and 5083 aluminum plate all belong to 5 series Al-Mg alloy, the main alloying element is Mg, with medium strength, good forming and processing performance, corrosion resistance, weldability, wide range of use. The thickness of aluminum alloy high voltage switch is generally between 4-90mm, width between 700-2700mm, surface requirements are generally not strict, most of the thickness within 20mm need to annealing to O state, other are in line with the company's internal control indicators.
