Introduction
Product Overview
The switch case is made of cold-rolled SUS304L stainless steel, all of which are welded except the casing, which improves the corrosion resistance of the case, reduces the annual air leakage fate and prolongs the overhaul period (10 years) To improve the technology of porcelain bushing;
Effectively prevent corona discharge in the operation of the switch, completely avoid the phenomenon of porcelain crack caused by the original resin seal by the use of gas insulation mode, and to adapt to the coastal humid and high-altitude areas, it also adopts the structure of insulated cable in and out line, effectively increases the electric clearance and creepage distance of the electrified parts of the equipment, and Installs high-voltage explosion-proof device on the opposite side of the operating mechanism, even it internal failure occurs, the safety accident will not happen because of the sudden increase of the gas pressure in the box. The manual locking device is installed to effectively prevent misoperation when the power is cut off.
