Cabinet dimensions (per unit)
- C Load switchgear: Width 350mm × Deep 880mm × High 1480mm
- F Fuse combination cabinet: Width 350mm × Deep 880mm × High 1480mm
- V Circuit breaker cabinet: Width 500mm × Deep 880mm × High 1480mm Cable entry/exit method: cables enter and exit from the bottom; wall‑mounted installation supported.
Operating environment
Ambient temperature: -40°C to +40°C; altitude ≤ 1,000 m; custom options available for higher altitudes; resistant to humid, salt‑fog, dusty, and condensation‑prone environments.
Application scenarios:
- Urban Distribution Network Project : Urban cable renovation, municipal switchgear stations, cable branching, and urban road distribution networks
- Box-type substation accessories : European style / American‑style prefabricated pad-mounted transformer: high‑voltage incoming and outgoing lines, and core protection unit.
- New energy industry : Centralized photovoltaic power plants, wind farm collection line segmentation, and grid-connection protection cabinets
- Major infrastructure projects : Subway stations, tunnels, high-speed rail stations, airports, hospitals, data centers, and distribution rooms in commercial complexes
- Industrial and mining area : Internal power distribution in high-dust, corrosive, and humid industrial areas such as chemical plants, metallurgical facilities, mines, and oilfields.
- Harsh outdoor operating conditions : Coastal salt-spray areas, high-humidity basements, extremely cold regions, and locations subject to short-term water immersion conditions
Product Advantages:
- Fully sealed and fully insulated, maintenance-free operation. A charged conductor is entirely enclosed within 304 Inside the stainless steel welded gas tank, SF6 Gas insulation effectively isolates moisture, dust, and small animals, eliminating the need for gas replenishment, cleaning, or maintenance during operation.
- High level of security protection Air box IP67 Sealed protection, fully equipped Five-Prevention Mechanical Interlock , preventing energized closing, erroneous grounding operations, and electric shock from opening the door; it features a built-in pressure-relief channel, ensuring that internal faults do not cause arc flash to escape outward.
- Modular free-assembly Divided into C (load switch), F (fuse assembly), V (Circuit breaker) Three standard modules, which can be freely combined and expanded to meet the requirements of two‑remote operation. / Three-remote intelligentization FTU , Temperature measurement module installation and upgrade.
- Compact in size, reducing civil engineering costs. The minimum width of a single unit is only 350mm , compared with traditional air-insulated ring main units, the footprint is reduced by 40% It can be installed in both compact switchgear rooms and outdoor enclosures.
- Extremely adaptable to the environment SF6 The insulation performance is unaffected by low temperatures and high-altitude atmospheric pressure variations. -40℃ It can operate stably over the long term in extremely cold, coastal salt‑mist, and underground humid environments.
- Optional primary–secondary integration Integrates electronic instrument transformers and intelligent protection terminals to enable remote signaling, remote measurement, and remote control functions for distribution automation, thereby supporting smart grid modernization.
