- Top pressure equalizing cover structure: the pressure equalizing cover is made of high-quality LY2 pure aluminum plate, and the welding process adopts sub arc welding machine to ensure that aluminum oxidation does not occur when placed in the air for a long time. Its radius of curvature contains 550kV power frequency voltage, and corona does not occur on the pressure equalizing cover. In particular, the parts arranged above require hot-dip galvanizing after metal processing to prevent iron oxidation in the air, Over a long period of time, the above components will be oxidized, resulting in corona discharge.
