20kV / 230kV / 245kV HGIS-252R Gas-Insulated Hybrid Switchgear
Voltage range: 72.5kV, 126kV, 145kV, 170kV up to 252kV
Rockwill HGIS-252R Hybrid Switchgear is a compact, factory-assembled and high-voltage tested switchgear unit, engineered for rapid on-site installation and energization. It adopts the identical core technology as the ABB PASS M0H, a member of ABB’s high-voltage hybrid switchgear PASS (Plug and Switch System) family.
The HGIS-252R Hybrid Switchgear integrates all functionalities of a complete switchyard into a single subassembly, designed with an H-configuration for high-voltage network connections. It features traditional air-insulated interequipment connections on one side, while enclosing selected bay functionalities in single-phase gas-insulated enclosures on the other, including:
- Gas circuit breaker
- Combined disconnector and earthing switch
- Voltage transformers & voltage sensors
- Current transformers
- Motor drive (optional)
- Fast earthing switch (optional)
- Plug-in cables (optional)
The Rockwill HGIS-252R is fully factory-assembled and tested, ready for rapid on-site installation and energization upon delivery.
