Key words:
ESR Air series intelligent environmentally friendly switch equipment
ESRAir series intelligent environmentally friendly switchgear uses dry air as the insulating medium in the gas chamber, eliminating SF6 gas and achieving green environmental protection. The gas chamber employs a dry air micro-positive pressure technology to prevent humid gases from invading the gas chamber and affecting insulation. The gas chamber is made of 304 stainless steel to prevent rusting of the cabinet due to humid air and salt mist. Throughout the entire operational life cycle of the equipment, there is no need for gas recovery treatment, resulting in no pollution and safe, reliable operation.
