- Humidity: Daily average humidity ≤95% , resistant to rain and short-term waterlogging
- Incoming and outgoing circuits: 2 Circuit~ 8 Flexible circuit configuration (one input to multiple outputs, multiple inputs to multiple outputs)
Common external dimensions (mm)
2 circuits: 800×700×1020; 4 circuits: 1040×700×1020; 6 circuits: 1390×700×1020. Enclosure material: cold-rolled steel sheet with powder coating / 304 stainless steel.
Application scenarios:
- Urban Distribution Network Cable Renovation : Urban road cable networks, undergrounding of overhead lines in urban areas, and municipal cable branch connection nodes
- Distribution for Residential and Commercial Buildings : Residential communities, office buildings, shopping malls, and mixed-use complexes 10kV Cable Branch Distribution
- Used in conjunction with a packaged substation. : Cable collection at the front end of European‑style pad-mounted substations; centralized incoming and outgoing wiring for multiple substations.
- Public infrastructure projects : High-speed rail stations, airports, hospitals, tunnels, and underground utility tunnels—high-voltage cable transitions
- Industrial and mining facilities, new energy power stations : Branch and tap connections for collector circuits in industrial parks, photovoltaic power plants, and wind farms
- Road lighting, scenic area power distribution : Urban street lighting trunk lines, outdoor high-voltage distribution branch points in cultural and tourism parks
Product Advantages:
- Fully insulated and fully sealed, with a high safety factor. Adopting the European style T The type features a touch‑safe, pre‑molded silicone rubber connector with no exposed live parts, ensuring that accidental contact will not result in electric shock. The enclosure is rain‑ and dust‑proof, and the connector is waterproof, capable of withstanding brief immersion.
- Maintenance-free design, low O&M costs After outdoor installation, no periodic maintenance or cleaning is required; the cable joint’s sealing structure is stable, ensuring a long service life under normal operating conditions. ≥20 Year.
- Flexible wiring scheme and easy scalability. Support 2~8 Any combination of incoming and outgoing lines can be equipped with… SF6 Load switches, surge arresters, and short-circuit fault indicators enable rapid identification of line fault locations.
- Compact footprint, easy installation Direct burial outdoors / It can be installed on the ground and does not require a dedicated switchgear room, significantly reducing civil‑engineering costs compared with conventional switchgear cabinets.
- Strong resistance to harsh environments The stainless steel enclosure is resistant to coastal salt spray and corrosive gases in industrial areas, and it avoids gas liquefaction even in low-temperature environments, ensuring stable operation in both extremely cold and rainy regions.
- High construction efficiency Plug‑in cable joints enable rapid on‑site connection, eliminating the need for on‑site cast‑in‑place insulation and significantly shortening the cable termination construction schedule.
