The RGIS Type C-GIS is a compact gas-insulated switchgear designed for medium-voltage systems. Integrating a vacuum circuit breaker, a three-position disconnector, and an intelligent control unit, it delivers high reliability and cost-effectiveness as its core advantages. Rated for 12 kV / 24 kV / 40.5 kV indoor distribution applications, it provides safe and efficient power distribution for critical loads.
Compact and space-saving: Modular design optimizes floor space utilization; pre-assembled enclosure for easy installation and transport; supports expansion on both sides.
Safe and reliable: Fully sealed stainless steel gas compartment; three-position disconnector with mechanical interlocks; multi-chamber partitioning with pressure relief channels-multiple layers of protection eliminate safety risks.
Intelligent and easy to maintain: Integrated measurement, protection, and control unit with automation capability; clean, user-friendly interface; compliant with both international and domestic standards.
Cost-effective: High-reliability vacuum interrupter with extended maintenance intervals; one-stop customization service balancing performance and lifecycle cost.
