Product Details of DFW Series
1. Product Introduction
DFW series outdoor high-voltage cable branch box is the core power distribution equipment for 10kV/35kV distribution network cabling projects. It adopts a fully insulated, fully sealed and modular structure, compatible with European/American cable joints, and can realize cable T-connection, ring network, radial power supply and multi-circuit branching. The product has no exposed live parts, high protection level and maintenance-free operation, and is widely used in urban network transformation, residential communities, parks, municipal and industrial and mining power distribution. It replaces traditional overhead branching, improving power supply reliability and line safety.

3. Main Features
Fully Insulated and Sealed, Safe and Reliable
No exposed live parts, touchable without electric shock, eliminating the risk of personal electric shock; sealed, moisture-proof, dust-proof and corrosion-resistant, capable of operation in water.
Compact Structure, Small Footprint
Small size, light weight, easy installation, suitable for narrow spaces and pole-mounted/floor-mounted/underground installation.
Flexible Branching, Strong Networking Capability
Supports multi-circuit incoming and outgoing lines, easily realizing ring network, dual power supply and multi-circuit branching, simplifying the distribution network topology.
Maintenance-Free, Long Service Life
Fully sealed and oil-free, no daily inspection and maintenance required, adaptable to harsh environments and stable operation for a long time.
Easy Fault Troubleshooting, Efficient Operation and Maintenance
Can be equipped with fault indicators to quickly locate short-circuit/ground faults, reduce power outage range and shorten repair time.
High Cost Performance, Cost Reduction and Efficiency Improvement
Reduces cable and equipment investment, with fast construction and short construction period; the comprehensive cost is better than the ring main unit scheme.
4. Application Scenarios
• Urban power grid cabling transformation, residential communities, commercial complexes
• Industrial and mining power distribution such as industrial parks, mines, chemical industry and metallurgy
• Municipal roads, subways, airports, stations, hospitals, schools
• Outdoor/underground/box substation supporting cable branching and ring network power supply
• Rural power grid upgrading, old line transformation, temporary power supply projects
