Epoxy Resin Casing Insulation Maintenance Method

Pay attention to the installation details of epoxy bushing to prevent the top seal from failing. The top seal of epoxy resin bushing is generally divided into epoxy resin cast bushing itself and epoxy bushing manufacturer lead seal. Nowadays, most substations have elastic corrugated plates on the top of the main transformer oil storage cabinet, which work together with the compression spring to adjust the temperature change. When the maintenance personnel assemble the elastic corrugated plate, the sealing gasket on the oil storage cabinet must match the sealing ring between the nut on the conduit to prevent the corrugated plate from cracking. The epoxy bushing for transformer lead is generally a cable-through structure, and the seal between the top terminal block and the conductive head must be strict, otherwise rainwater will penetrate into the transformer along the casing conductive head, the top terminal block and the cable along the conduit.
