GIS is the switch station we usually see, it is known as the high voltage distribution device. GIS high voltage switch use the ultra wide aluminum sheet. The main alloy is 5052 aluminum sheet and 5083 aluminum sheet.

The 5052 aluminum sheet contains 2.5% Mg, widely used as the antirust aluminium, It has good workability, medium static strength, high fatigue strength, good weldability, and good corrosion resistance.

5083 aluminum sheet products process, through the alloy composition, casting process optimization, homogenization heat treatment and rolling process test, the product performance and foreign materials, to meet user requirements.
High voltage is hard to avoid in the production of industrial environment, to ensure the safety of the electricity production environment is the foundation of the enterprise in good running condition, also ensure the worker is the important measure of life and property safety, so the high voltage switch is very important, because of the ultra wide aluminum sheet with excellent features, it is widely use in the field of high voltage switch production.
Mega aluminum production GIS shell ultra wide aluminum sheet material, the thickness is generally between 4--30mm, width is 700-2700mm, some products below 20mm need to be annealed. The normal size is as following.
