Description
Bushing for outdoor applications for SF6 insulated devices.
It is built with an epoxy resin core that gives mechanical stability and guarantees a good insulation level. Outside is coated with silicone rubber with high weathering resistance.
This insulator is supplied with an EPDM o-ring gasket and a nuts and washers set made of nickel-plated brass for the outdoor cable connection.
It is fixed to the tank through six OT58 brass fittings and, upon request, with an aluminium flange that improves the stability.
This insulator is available also with a side capacitive output for voltage presence signaling.
