PGSbushing air-SF

FEATURES t la

It is composed of two parts: A, red epoxy bushing cons tutes the core of the insulator with solid mechanical strength and suitable for SF6 use. B, silicone rubber cover gran ng great insula ng performances in highly polluted environments. Resin bushing “A” can be used alone thanks to its EN 50181 C connec on. It has to be connected with the silicon cover “B” or with cable termina on before pu ng into opera the electrical equipment Resin bushing is supplied with an EPDM O-ring gasket and plas c safety cap for C connec cone, while B part is supplied with a small bag of silicone grease and nuts/washers set made of nickel-plated copper for the outdoor cable connec on. It has to be to the tank through six OT58 brass fittings and, upon request, with an aluminium ange that improves stability. Opera ng temperature from -25°C to +100°C.
