Environmentally friendly gas insulated ring network switch cabinet

Product Introduction

The ring network cabinet assembles several functional units and connecting busbars in the same dry air-sealed air box, with no exposed live parts. It has the advantages of full insulation, full sealing, maintenance-free live parts, small size, compact structure, and easy operation. The air box is made of 3.0mm thick stainless steel plate, which can effectively prevent corrosion caused by moisture and salt spray. The product has passed the opening and closing test, dynamic thermal stability test, zero gauge pressure test, internal combustion arc test, sealing test, mechanical test, electromagnetic compatibility test, etc., to maximize the safety of people and equipment. The cabinet is not affected by the external environment and has extremely high resistance to harsh environments.
