Product Introduction
The ring main unit assembles several functional units and connecting busbars in the same dry air sealed air box, without exposed live parts. It has the advantages of full insulation, full sealing, maintenance free live parts, small volume, compact structure, and easy operation. The air box is made of 3.0mm thick stainless steel plate, which can effectively prevent rust caused by moisture and salt spray; The product has passed the breaking and closing tests, dynamic thermal stability tests, zero gauge pressure tests, internal combustion arc tests, sealing tests, mechanical tests, electromagnetic compatibility tests, etc., to maximize personal and equipment safety. This cabinet is not affected by external environments and has extremely high resistance to harsh environments.
