Tungwell Gas-insulated Switchgear XGN80 voltage is from 12KV to 40.5KV. It is insulated switchgear fully enclosed and uses low pressure gas as the insulating medium. The product adopts imported three-dimensional five-axis laser welding equipment to ensure the overall air tightness, high strength, laser welding and small deformation. In order to ensure the stability of product quality, Tungwell introduced equipment such as helium mass spectrometer lead detector, lightning impulse, partial test and X-ray insulation inspection. Due to the introduction of precise production equipment and testing equipment, it is convenient for users to carry out supervision and sampling tests at the factory.
