ZX1.2 gas-insulated switchgear (IEC)

Safe, reliable and easy to use single busbar switchgear

ZX1.2 is part of ABBs successful ZX family of gas-insulated indoor switchgears for primary distribution level. The three-phase encapsulated, arc-resistant switchgear is equipped with separate gas-filled busbar and circuit breaker compartments.

The stainless steel gas tanks protect all high voltage parts inside permanently from soiling, humidity, entry of foreign bodies and other environmental influences resulting in a very reliable and practically maintenance-free switchgear. All switching devices are motor-operated and can be controlled remotely.

All panels are routine-tested and gas-filled in the factory. The use of plug-in busbar connections enables safe, fast and easy installation without the need for special tools.
