Product Overview
Operating as a highly reliable and zero-emission node in power distribution, this sf6 free gis (Gas-Insulated Switchgear alternative) features a highly flexible modular design. All primary high-voltage conductive parts are completely sealed within a solid insulating medium, achieving an outstanding IP67 protection grade. This fully touchable, sf6 free structure completely solves the risks associated with gas leakage and greenhouse gas emissions, guaranteeing stable operation even in extreme environments.
sf6 free switchgear Features & Benefits
- 100% Eco-Friendly (SF6 Free): Completely abandons SF6 gas in favor of solid insulation (epoxy resin) and environmentally friendly materials, ensuring zero pollution and zero gas leakage risks.
- Ultimate Safety (IP67): The primary circuit is fully encapsulated and fully insulated, featuring an IP67 protection grade and a safe, touchable exterior structure to protect personnel.
- High Reliability: Utilizes vacuum arc extinguishing technology combined with premium epoxy resin casting, ensuring stable switching operations under extreme loads.
- Compact & Modular Design: The cabinet is incredibly space-saving with standard module widths of 400mm and 500mm, allowing for flexible combinations and easy grid expansion.
- Intelligent Integration: Designed to seamlessly integrate with smart grid automation systems, featuring visible isolation fractures for enhanced operational monitoring.
