Rockwill HGIS-252R type Hybrid switchgear is a compact switchgear assembled and high-voltage tested switchyard for rapid installation and energization.
The same technology with ABB PASS M0H high-voltage hybrid switchgear family PASS (Plug and Switch System).

HGIS-252R type Hybrid switchgear encloses all functions of a complete switchyard in a single subassembly designed for connections to the high voltage network with an H configuration. On one side, it uses traditional air-insulated connections between equipment; on the other side, it encloses the selected bay functions in a single-phase gas-insulated housing:

- Gas Circuit breaker
--Combined disconnector and earthing switches
-Voltage transformers and Voltage sensors
-Current Transformers
-Motor drive option
-Fast earthing switch option
-Plug in cables option

HGIS-252R type Hybrid switchgea is completely factory assembled and tested, ready for rapid installation and energization.
