Product Description
This series of cable branch boxes is suitable for outdoor distribution networks with AC 50Hz, rated voltage 12 kV, and cable inlet and outlet lines.
It is widely used in industrial areas, residential communities, commercial centers, mining areas, airports, railways, port areas, power stations, and other distribution networks, especially suitable for urban power grid renovation projects. Features include:
- Fully insulated, fully sealed, maintenance-free, providing reliable personal safety protection;
- Simplifies urban cable network systems and saves investment;
- Outdoor type, dustproof, moisture-proof, flood-resistant, corrosion-resistant, with strong environmental adaptability and flexible configuration. Incoming and outgoing lines range from two to eight circuits, meeting various wiring requirements;
- Compact size, tight structure, elegant appearance, easy installation, maintenance-free, equipped with live display, optional short-circuit indicator, and lightning arrester;
- Small footprint, low profile, aesthetically pleasing design, blends well with the surrounding environment: flexible and diverse wiring schemes, extremely convenient for installation and operation;
- The 200A cable connector supports load-break operation and functions as an isolating switch. A short-circuit fault indicator can be installed to quickly locate faults;
- Flexible combinations of load switches or circuit breakers with cable connectors improve the flexibility of line operation, maintenance, and repair, reduce power outage duration, enhance power supply reliability, replace some ring network cabinets and switchgear stations, and reduce overall system costs.
Installation, Use, Maintenance, Order
When placing an order, the user must provide the following information:

Frequently Asked Questions
Q
Does your company hold any relevant international quality certifications?
Yes, our factory is ISO 9001 Quality Management System certified. Our products comply with international standards such as IEC (International Electrotechnical Commission) and CE. We can also apply for certifications specific to other countries upon customer request.
Q
What is your factory's production capacity? What is the annual output?
We operate a modern production base with advanced production lines. Our annual production capacity exceeds 10,000 units. We manufacture oil-immersed and dry-type transformers ranging from 30KVA to 20MVA.
Q
How do you ensure product quality?
Our quality assurance spans the entire process:
Source Control: Strict supplier screening and incoming inspection of raw materials.
Process Control: Quality control points established at critical production stages.
Final Inspection: Each transformer undergoes rigorous factory testing before shipment, with test reports provided.
Q
What types of transformers do you primarily manufacture?
We mainly produce:
Oil-immersed transformers: Suitable for outdoor, power plant, and large industrial projects, offering a wide power range and high cost-effectiveness.
Dry-type transformers: Ideal for indoor, commercial buildings, hospitals, data centers, and other locations with high fire safety requirements.
Q
What are the primary materials for transformers? Are windings copper or aluminum?
We offer both materials:
Copper windings: Higher conductivity, better efficiency, smaller size, high mechanical strength, longer lifespan, but higher cost.
Aluminum windings: A lighter weight option that provides cost-effective advantages for specified systems.
Q
What are the main application areas of the DFW-10/630 cable branch box?
It is widely applied in outdoor power distribution networks (AC 50Hz, 12 kV) across industrial zones, residential neighborhoods, commercial hubs, stations, and railways. It is particularly designed to upgrade urban power grids with its fully insulated, sealed, and maintenance-free features.
