Product Highlights
Space-Efficient Design: Compact cabinet structure optimized for tight spaces, significantly reducing the required substation footprint.
Eco-Friendly Insulation: Uses dry air as the insulation medium—zero SF6 gas, no greenhouse effect, and perfectly safe for high-altitude or sensitive areas.
Maintenance-Free Reliability: A fully sealed primary circuit design protects components from dust, humidity, and corrosive elements, ensuring years of trouble-free operation.
Operational Safety: Features standard mechanical interlocks (Load Switch ↔ Earthing Switch ↔ Cabinet Door) to prevent misoperation, ensuring total operator safety.
Modular Configuration: Highly flexible design; easily expandable and configurable with manual/electric load switches, vacuum circuit breakers, or fuse combinations to meet specific project needs.
Typical Applications
- Urban and rural distribution networks.
- Commercial complexes, industrial parks, and residential communities.
- Schools, hospitals, and critical municipal infrastructure.
