DFW 10kV Series European High Voltage Cable Junction Box

Overview of DFW High Voltage Cable Junction Box

The DFW series European high voltage cable junction box is a core device in modern power distribution systems. Designed for node connections in 10kV, 24kV, and 35kV cable networks, this junction box serves as the primary solution for tapping and routing cables after they exit switchgear or ring main units.

Engineered with imported high-insulation rubber and optional SF₆-insulated load switches, the DFW cable branch box guarantees safe, sealed, and reliable operation. Its structure is fully enclosed and maintenance-free, with IP33 protection level, capable of withstanding harsh outdoor conditions including flooding in underground environments.

This product is widely used in urban distribution networks and various demanding industrial applications, including mining, petrochemical, automotive, cement, steel, and commercial centers.

Product Features

• Compact Design: Minimal footprint, simplified installation, and no routine maintenance required.
• Corrosion-Resistant Enclosure: Fabricated from 2mm galvanized or stainless steel with anti-corrosion coating for long-term durability (≥30 years lifespan).
• All-Weather Protection: Operates reliably under extreme temperatures, flooding, high humidity, dust, and wind.
• Fully Sealed and Insulated: High-voltage live components use silicone rubber or EPDM pre-molded connectors, ensuring complete safety and eliminating the need for insulation distance.
• Flexible Configuration: Supports up to seven outgoing cable ways and ring network setup via SF₆ load switches.
• Switchable Connectors: 200A connectors can be plugged and unplugged under load, functioning like a switch.
• Quick Fault Detection: Optional fault indicators enable rapid circuit troubleshooting.
• Cost-Efficient: Low initial investment, reduced cable length, and space-saving—ideal for dense urban and retrofit projects.

Applications

PINEELE’s DFW high voltage cable junction boxes are extensively used in:

• Urban medium voltage power distribution networks
