Product Overview
The high-voltage cable branch box is a critical node device in 10kV distribution network systems, primarily responsible for the branching, connection, and conversion of cable lines. As an essential component of urban distribution network cable retrofit projects, this product effectively addresses the complexity of traditional overhead line branching and the large footprint associated with conventional setups, providing reliable assurance for the safe and stable operation of the distribution network.
Structural Features
This product adopts a fully insulated and fully sealed structural design. The core components typically utilize high-quality silicone rubber or epoxy resin castings to ensure stable internal insulation performance. There are no exposed live parts inside the enclosure, which significantly enhances operational safety and effectively prevents electric shock to personnel and short-circuit accidents caused by small animals.
Main Functions
The high-voltage cable branch box is primarily used to realize the branching and connection of multi-circuit cables, meeting the multi-directional power supply requirements of the distribution network. The equipment can be optionally configured with a short-circuit fault indication function to facilitate rapid fault location and minimize outage time. Additionally, the product design supports live-line working, eliminating the need for a full system shutdown during line maintenance or modification, thereby significantly improving power supply reliability.

Ordering Information
Dear Customer, to ensure that the 12kV high-voltage cable branch boxes (DFW Series) you order precisely match your project requirements and are delivered smoothly, please provide the following detailed technical information and requirements before placing your order:
Core Electrical Parameters and Drawings
●Primary Electrical System Diagram: Please provide a detailed main circuit wiring scheme (primary system diagram), clearly specifying the number of incoming/outgoing feeder circuits, the number of spare circuits, and the cable nominal cross-sections (e.g., 35mm² ~ 300mm², etc.).
●Basic Model and Quantity: Specify the exact model, number of branches, rated voltage, rated current, and order quantity for the required products.
●Switchgear and Protection Configuration:
- Whether SF₆ load switches or vacuum circuit breakers are required, and specify their models and quantities.
- If electric operating mechanisms are selected, please specify the operating power supply voltage (e.g., DC 110V/220V or AC 220V).
- Specify secondary protection function requirements and configuration needs for other automation devices (such as telemetering, telesignaling, short-circuit fault indicators, surge arresters, etc.).
Structural and Appearance Requirements
●Enclosure Material and Color: Specify the enclosure material (e.g., high-quality cold-rolled steel plate, 304 stainless steel, or SMC composite material, etc.) and the surface coating color (default is environmentally-friendly green or military green if no special requirement is specified).
●Special Environment Customization: If the equipment is to be installed in special environments such as high altitude (>1000m), high salt spray, heavy pollution, or extreme temperatures (e.g., below -25°C), please provide a detailed description at the time of ordering so that reinforced insulation or anti-corrosion design can be applied.
Commercial and Project Information
●Basic Project Information: Provide your company name, project name, approximate project address, and expected delivery timeline.
●Contact Information: Provide the name and phone number of the technical contact person and the commercial liaison person so that our engineering team can communicate with you promptly to confirm technical details.
●Accessories and Spare Parts: If there are any special spare parts or accessory requirements, please list the names and quantities together.
Tip: Since high-voltage equipment is mostly custom-produced, the final quotation, technical parameters, and delivery schedule for specific products shall be subject to the technical agreement and commercial contract signed by both parties. Thank you for choosing our products!
