Gis high-voltage switch shell material with good heat dissipation.

Gis high-voltage switch shell material with good heat dissipation.

GIS is the switching station that we can often see, also known as high voltage power distribution device. The raw material used for GIS high voltage switch is ultra wide wide alloy aluminum plate. The alloy of aluminum plate for gis high voltage switch is generally based on 5052 alloy aluminum plate and 5083 alloy aluminum plate, while 1060 aluminum plate, 3003 aluminum plate and 5754 aluminum alloy plate are relatively less.

Advantages of GIS Shell Products

The GIS shell is made of aluminum alloy, which has the advantages of light weight, low temperature rise and corrosion resistance. The aluminum shell adopts two forms of high-strength cast aluminum alloy and aluminum plate coil welding. The shell extraction adopts a stretch forming technology to avoid the irregularity of the shell interface. It is convenient to implement automatic welding process and improve welding quality. The aluminum shell has light weight; the temperature rise of the shell is almost not affected by the flow, which is conducive to safety and the life of the sealing ring; the anti-corrosion performance has also been greatly improved. The outer surface of the aluminum shell is coated with THU iron red epoxy primer and B05 acrylic polyurethane enamel for excellent corrosion resistance.
