Metalpartitioned single busbar system for all applications – with raised cable terminations for very simple cable installation.
ZX1.2 switchgear offers all solutions with combined protection and control devices or pure protection devices. The gas insulation with SF6 increases operator safety, as inadvertent contact with live parts is impossible.

ZX1.2 switchgear consists of metal-partitioned circuit breaker and busbar gas compartment for single busbar applications with customer friendly aspects like a very high cable fixing point. The cables are accessible from the rear. All switching devices can be remote controlled and as an option mechanically interlocked.
It combines progressive and future-oriented concepts and technologies, which include a high flexibility for measuring systems combined with digital bay control technologies or conventional devices as well as plug-in technology at all ends for easy installation.
The extremely long service life of gas-insulated switchgear is optimally achieved by the use of the insulating gas sulphur hexafluoride, an inert gas which not only insulates but also protects all the high voltage components throughout the entire switchgear life.
Either signal detection by sensors or instrument transformers together with a direct bus to station automation system or conventionally by wire to the control center is available.
ZX1.2 switchgear are factory assembled and tested sealed pressure switchgear as defined by the current IEC standard.
A GIS fully protected against environmental influences with arc-proof cubicles and vacuum circuit breakers in a compact housing, suitable for all requirements.
