I. Overview
This product is widely used for cable tapping in 10kV power systems. Its connection method is simple, flexible, convenient, safe and reliable. The cabinet is made of stainless steel plate, which is sturdy and durable. The live part is a fully insulated and fully sealed structure. If anti drying and touchable cable heads are used, they can also withstand flood invasion, greatly improving power supply reliability. This product is widely used in urban industrial communities, residential areas, and renovation projects, which can greatly save electrical equipment and cable investment and improve power supply reliability.
II. Product Structure Features
This product adopts a high-performance sulfur hexafluoride load switch with SF6 insulation gas and a touchable shielded imported synthetic rubber cable joint. It has strong breaking ability for active load and no-load cable current, as well as short-circuit current closing ability. It can also be equipped with lightning arrester and grounding fault indicator according to user requirements.
Each ring network cable in this series of products is equipped with a load switch or Vacuum circuit breaker. Any branch circuit can be freely withdrawn and put into operation, and other ring network circuits are not affected. Fuses can also be attached to the load switch. When a short circuit fault occurs in a branch circuit, the fuse on the branch circuit can quickly disconnect the faulty circuit and strike the release of the load switch to open it, isolating the faulty circuit and ensuring the continuity of power supply for non faulty branch circuits.

DFW-SF6 High Voltage Cable distribution box for Reliable 35kV Power Distribution Solutions
At Jihui Electric Group Co., Ltd., we design and manufacture reliable medium and low voltage power transmission and distribution equipment for modern electrical networks. Our DFW-SF6 High Voltage Cable Distribution Box is one of our key products developed for safe, stable, and efficient cable connection applications in power distribution systems up to 35kV.
With years of experience in electrical equipment manufacturing, we understand that every power project requires equipment that can operate safely under demanding conditions. Our SF6 high voltage cable distribution box combines advanced insulation technology, strong mechanical structure, and flexible configuration options to meet the needs of power companies, engineering contractors, industrial users, and renewable energy projects.
Located in Yueqing Economic Development Zone, China, we focus on research, manufacturing, quality control, and customer service. Our production systems follow ISO9001 quality management standards, ISO14001 environmental management requirements, and ISO45001 occupational health and safety practices. We provide complete power distribution solutions, including Cable accessories, ring main units, Prefabricated Substations, combination transformers, SF6 load switches, and Vacuum circuit breakers.
The DFW-SF6 High Voltage Cable Distribution Box is a compact electrical distribution device designed for medium and high voltage cable connection, branching, and control applications. It is mainly used in power distribution networks where safe cable management, reliable insulation, and long-term operation are required.
Unlike traditional cable distribution equipment, our SF6 Gas Insulated Cable Distribution Box uses SF6 gas as an insulation medium inside the sealed enclosure. This design helps reduce the influence of external conditions such as humidity, dust, pollution, and temperature changes. As a result, the equipment can maintain stable electrical performance even in complex outdoor environments.
Our DFW-SF6 cable distribution box is widely used in urban power grids, industrial plants, renewable energy facilities, commercial buildings, transportation infrastructure, and other projects requiring dependable medium voltage power distribution.
The working principle of our SF6 Gas Insulated Cable Distribution Box is based on the excellent insulation characteristics of sulfur hexafluoride gas. Inside the sealed metal enclosure, SF6 gas provides electrical insulation between conductive components, helping prevent unwanted electrical discharge and improving system safety.
When high voltage cables enter the distribution box, internal connection components safely distribute electrical energy to different outgoing circuits. Depending on project requirements, the equipment can be configured with cable connectors, grounding switches, load switches, and other protection components.
During normal operation, electrical current flows through the internal conductive path. When abnormal conditions occur, such as short circuits or maintenance requirements, protection devices can isolate the circuit to improve equipment safety and reduce downtime.
Step 1: Incoming high voltage cables connect with the internal cable terminals.
Step 2: Electrical energy is transferred through insulated conductive components.
Step 3: SF6 gas provides stable insulation protection inside the sealed chamber.
Step 4: Outgoing circuits distribute power safely to different loads or equipment.
Step 5: Protection devices help isolate faults and maintain network reliability.
This simple but reliable design allows our equipment to provide long service life with less maintenance compared with many traditional open-type distribution solutions.
The biggest advantage of our SF6 insulated cable distribution box is its reliable insulation performance. SF6 gas has strong dielectric strength, which allows the equipment to maintain stable operation in high voltage environments.
This insulation method also helps reduce the size of the equipment. Compared with conventional air-insulated solutions, our SF6 cable distribution box can achieve a more compact structure while maintaining excellent electrical safety.
Modern cities and industrial projects often face limited installation space. Our DFW-SF6 High Voltage Cable Distribution Box features a compact structure, making it suitable for locations where space efficiency is important.
The smaller footprint helps customers optimize equipment layout, reduce installation difficulty, and improve project flexibility. It is especially suitable for urban distribution networks and commercial areas with strict space requirements.
Power distribution equipment often works in outdoor environments where it faces rain, dust, temperature changes, and pollution. Our outdoor SF6 cable distribution box is designed with a sealed enclosure structure to improve environmental protection performance.
The enclosure design helps prevent moisture and external particles from affecting internal electrical components. This allows the equipment to maintain reliable operation in different climate conditions.
Every power project has different technical requirements. We provide flexible product configurations according to customer specifications, including cable connection methods, rated voltage levels, switching requirements, and installation conditions.
Whether the project is a new power network installation or an upgrade of an existing system, we can provide suitable medium voltage cable distribution solutions.
Safety is always one of our main design goals. Our DFW-SF6 High Voltage Cable Distribution Box is developed with practical maintenance considerations. Clear internal structures and reliable protection components help engineers complete inspection and service work more efficiently.
By improving operational safety and reducing unexpected failures, our equipment helps customers achieve more stable power supply performance.
Based on our manufacturing experience and customer application feedback, SF6 insulated cable distribution equipment provides several advantages compared with traditional air-insulated solutions.
