The 630A 12/24kV Deadbreak Bushing are designed for Cable Branch Cabinet with Sf6 Switch. Separable connectors, such as 630A T-II deadbreak connectors can be used with these bushing. These bushing are made by Epoxy Resin. With the skirt make the Deadbreak Rotatable Feedthru Bushing can be used better.
Tests conducted in accordance with IEC60502-4 and IEC60137.
