Cabinet external dimensions
- Load switch C Unit: Width 400mm× Deep 887mm× High 1450mm
- Circuit breaker V Unit: Width 500mm× Deep 887mm× High 1450mm
- Cable entry/exit method: cables enter and exit from the bottom; wall‑mounted installation supported.
Application scenarios:
- Urban Distribution Network Project : Urban cableization upgrade, switchgear stations, cable distribution boxes, and residential community substations
- Box-type substation accessories : Prefabricated packaged substation with internal high-voltage incoming and outgoing lines, and transformer protection and control unit
- Public infrastructure : Power supply for subways, tunnels, airports, hospitals, high-speed rail stations, sports venues, and data centers
- Industrial and mining area : Power distribution systems for high-dust, corrosive, and humid operating conditions in chemical plants, metallurgical facilities, mines, and similar environments
- New energy power station : Sectionalization and grid-connection protection for collector lines of wind and photovoltaic power plants
- Special harsh environment : High-altitude areas, permafrost regions, coastal salt-spray corrosion zones, and explosion-proof industrial facilities
Product Advantages:
- Environmentally friendly and non-toxic SF₆ : All high-voltage primary components are made of epoxy resin. APG The device features an integral hermetic seal, eliminates the use of sulfur hexafluoride gas, ensures zero leakage and no greenhouse gas emissions, and requires no periodic gas‑recharge inspections.
- Fully insulated, fully sealed, and maintenance-free The energized conductor is entirely encapsulated in epoxy resin, effectively isolating it from dust, condensation, moisture, and salt spray, thereby requiring virtually no routine inspection or maintenance during operation.
- Safety, explosion-proof, and fault‑propagation prevention : Three-phase independent solid-sealed modules; a single-phase fault will not cause breakdown to propagate to other phases; vacuum arc-extinguishing chamber + The insulating sleeve features double-layer protection and is explosion-proof.
- Extremely adaptable to various environments. : Low temperatures do not cause gas liquefaction, and high altitudes do not result in deformation due to pressure differentials. -45℃ It can operate reliably in extremely cold environments.
- Modular assembly ： C (load switch), V (circuit breaker), F (Fuse combination) Three standard modules, freely assembled and expanded on-site, with intelligent upgrades in the later stage. FTU The temperature-sensing module can be directly retrofitted and upgraded.
- Compact footprint : The cabinet width is as narrow as 400mm Compared with conventional air‑insulated switchgear, its footprint is significantly reduced, thereby lowering civil‑engineering costs for the distribution room.
- Improve the mechanical interlock : Mechanical interlocks are mandatory among the switch, grounding device, and cabinet door to prevent misoperations, opening the door under voltage, and other personal safety incidents.
