High Voltage Cable Branch Box

Product Details of DFW-12

1. Product Overview

DFW-12 series outdoor high-voltage cable branch box is key power distribution equipment for 10kV distribution network cable projects. It is mainly used for cable T-connection, tapping, ring-network switching and multi-branch power supply.

Adopting fully insulated, fully sealed structure with no exposed live parts, it is compatible with European-type cable connectors. It features high safety, compact structure, maintenance-free operation and flexible networking. It is widely used in urban power grids, residential quarters, industrial parks, municipal engineering, mines and industrial and mining enterprises, effectively replacing traditional overhead line branches and greatly improving power supply safety and reliability.

3. Product Advantages

1. Fully insulated and fully sealed, high safety level

   No exposed live parts, touch-safe and anti-electric shock, eliminating potential personal safety risks. The fully sealed structure is waterproof, dustproof, anti-condensation and corrosion-resistant, ensuring stable long-term operation in harsh outdoor environments.

2. Compact structure, small footprint and easy installation

   Small size and light weight, supporting pole-mounted, floor-mounted and underground installation. Simple construction and short construction period, especially suitable for narrow sites and renovation projects.

3. Flexible branching, strong networking capability

   Supports multi-circuit incoming and outgoing lines, easily realizing ring-network power supply, dual-power switching and multi-branch distribution, simplifying the distribution network structure and improving power supply flexibility.

4. Maintenance-free, stable operation and long service life

   Fully insulated and oil-free design, requiring no daily inspection and maintenance. Good aging resistance and corrosion resistance, long service life and low operation and maintenance cost.

5. Fast fault location, high operation and maintenance efficiency

   Can be equipped with fault indicators to quickly locate short-circuit and grounding faults, reduce power outage range and shorten repair time, ensuring continuous power supply.

6. High cost-performance, lower investment

   Lower cost, faster construction and less material consumption compared with traditional ring main units, significantly reducing investment for power grid renovation and projects.

4. Application Scenarios

• Urban power grid cabling renovation and old community reconstruction

• Residential quarters, commercial complexes and office buildings

• Industrial parks, mines, chemical, metallurgy and other industrial power supply

• Municipal roads, subways, airports, stations, hospitals, schools

• Matching for box-type substations, cable branching and ring-network power supply

• Rural power grid upgrading, temporary power supply and line reconstruction
