The DFW-12 Cable Branch Box is a medium-voltage outdoor power distribution device designed for 12kV cable networks. It functions as a node for branching and connecting multiple power cables, providing reliable cable connection and isolation solutions in looped or radial power systems.
Product Advantages
Flexible Cable Management
Supports various wiring configurations including radial, ring network, and T-branch systems.Enhances the adaptability of distribution networks and simplifies future expansions or modifications.
Space-Saving Design
Compact dimensions allow installation in confined outdoor locations such as sidewalks or alleyways.Enables high-density network distribution without large substations or extensive civil works.
Enhanced Safety Protection
Fully enclosed structure ensures that live parts are shielded from direct contact.Equipped with surge arresters and grounding systems to prevent damage from voltage spikes and faults.
Easy Maintenance
Clear layout of cable terminals and compartments facilitates inspection and replacement.Components are arranged for easy access without the need for complex tools or disassembly.
Product Features
Durable Enclosure
Outer casing is made from stainless steel or weather-resistant composite materials.Provides resistance to corrosion, UV radiation, and harsh environmental conditions.
Modular Interface Design
Features standardized plug-in type cable connectors with touch-proof construction.Compatible with various cable sizes and types, improving versatility in network deployment.
Multiple Cable Access Points
Typically offers 4 to 8 cable entry terminals, depending on the model and configuration.Allows multiple circuits to be connected and isolated independently.
