Product introduction
The ring network cabinet assembles several functional units and connecting busbars in the same dry air-tight gas box, with no exposed electrified parts, featuring the advantages of full insulation, full sealing, maintenance-free electrified parts, small volume, compact structure, and convenient operation, etc. The product adopts 3.0mm thick stainless steel plate, which can effectively prevent rust and corrosion caused by moisture and salt spray. The air box adopts 3.0mm thick stainless steel plate, which can effectively prevent rust and corrosion caused by moisture and salt fog; 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., which maximizes the protection of personal and equipment safety. The cabinet is not affected by the external environment and has a very high resistance to harsh environmental performance.
