Outdoor Gas Circuit Breaker

Introducing our advanced Outdoor Gas Circuit Breaker series, engineered for high-voltage switching reliability in substations and industrial power systems. This SF6 gas-insulated breaker ensures arc-quenching efficiency and minimal maintenance, suitable for demanding outdoor environments. For various voltage ratings, our product line also features the 66KV SF6 Circuit Breaker, delivering stable performance for medium-voltage grids. The 66KV Gas Insulated Circuit Breaker offers compact design and excellent dielectric strength. When outdoor resilience is paramount, the 66KV Outdoor SF6 Circuit Breaker withstands harsh weather conditions. For heavy-duty applications, the Tank Type SF6 Breaker provides robust fault interruption with live-tank construction. All these breakers share advanced gas insulation technology, ensuring safety and longevity.

The Outdoor Gas Circuit Breaker is designed with a cutting-edge puffer mechanism and optimized interrupter geometry, achieving rapid arc extinction under fault currents up to 40 kA. It supports frequent switching operations with a mechanical endurance exceeding 10,000 CO cycles and is available with optional integrated digital monitoring sensors for condition-based maintenance. The following table summarizes the main ratings and technical specifications.

Key features include:

• Sealed SF6 gas system with low leakage rate (less than 0.5% per year)
• Live tank design for easy CT integration and reduced footprint
• Motorized spring mechanism enabling remote and local operation
• Compliance with IEC 62271-100 and ANSI standards
• Corrosion-resistant galvanized steel structure for coastal environments
