Full SF6 Gas Insulation for Unmatched Reliability
The entire main circuit is sealed in a high-integrity SF6 gas chamber, providing 100% insulation against external environmental factors. Integrated pressure gauges continuously monitor gas density, ensuring consistent insulation performance and early warning of potential leaks, guaranteeing long-term stable operation.
5-Proof Mechanical Interlock for Maximum Operator Safety
Compliant with IEC 62271-200 international standards, the TSC-V 12kV RMU features a fully interlocked operating mechanism to prevent dangerous misoperations, including:
Compact Modular Design for Space Savings
With a footprint 30-50% smaller than conventional air-insulated switchgear, this compact gas insulated switchgear is perfect for space-constrained applications such as compact substations, underground power distribution rooms, and prefabricated substations. Its modular unit design allows flexible configuration to meet customized project requirements, and it is one of the core products in our domestic brand medium voltage switchgear product line.
Intelligent Monitoring & User-Friendly Operation
Equipped with advanced intelligent measurement and control instruments, the switchgear enables real-time monitoring of current, voltage, power, and fault status. The user-friendly front panel with clear ON/OFF status indicators, push buttons, and operation handles ensures simple, safe operation for both on-site and remote control scenarios.
