Air-insulated switchgear

We make wall bushings for both indoor and outdoor applications. If necessary, the bushings are clad with a silicone rubber casing, allowing them to be used in moist indoor spaces without additional protection.

EW / SEW
are oil-free switchgear bushings whose solid active part is made of resin-impregnated paper. The products have a condenser control and dry filling. The air side housing is made of either porcelain (EW) or silicone composite insulators (SEW) – on both sides or one side. When required, an active part without a housing is available for indoor operation. The bushings are designed for rated voltages of 52 to 800 kV and rated currents up to 4000 A.
