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.
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.
Safe Maintenance & Inspection Design
The lower cable compartment is fitted with transparent observation windows, allowing visual inspection of cable connections and grounding status without opening the cabinet. High-voltage DANGER warning labels and mechanical interlocks enforce strict operational safety protocols, ensuring compliance with global electrical safety standards.
