35kV Copper Busbar-linked Cable Branch Box (for Wind Power Applications)

The 35kV copper‑busbar cable branching box (for wind power applications) is a high‑voltage distribution device engineered for 35kV wind farms and grid modernization projects. Suitable for outdoor, indoor, or underground installation, it operates reliably in temperatures from –10℃ to +40℃ and relative humidity up to 95%, with excellent dust, moisture, corrosion, and seismic resistance. The box uses prefabricated copper busbars and plug‑in cable accessories to branch one incoming circuit into multiple outgoing circuits, greatly simplifying wiring and maintenance.

Featuring fully insulated, sealed, and waterproof construction with a maintenance‑free design and “five‑prevention” interlock mechanism, it ensures long‑term stable operation. The DFW‑35/630 series offers selectable rated currents of 200A, 400A, 630A, 1000A, and 1250A, and can be equipped with live‑line indicators, fault indicators, or surge arresters for monitoring and protection. Its compact size and flexible modules make it an ideal solution for wind farms, prefabricated substations, and ring‑network power units.

Outdoor type (also available in indoor type) with fully sealed design; “five-proof” safety and maintenance-free, providing reliable personal protection.

Environmentally friendly outdoor cable branch box with high-voltage live-line indicator, simplifying urban cable network systems and saving investment.

Outdoor design that is dustproof, moisture-proof, flood-resistant, and corrosion-resistant, with strong environmental adaptability and flexible configurations—from single incoming/outgoing lines to multiple circuits—to meet diverse wiring requirements.

Small footprint, compact structure, and elegant appearance; easy installation, convenient switching of operational modes, and flexible protection settings. Equipped with a live-line indicator, optionally with a short-circuit indicator and a surge arrester.

Minimal footprint and low profile with an attractive exterior that harmonizes with the surroundings; highly flexible wiring schemes and extremely convenient installation and operation.
