SF6 High Voltage Cable Branch Box With Switch

General Information

This product adopts a high-performance sulfur hexafluoride load switch with built-in SF6 insulating gas and a touch-shielded imported synthetic rubber cable joint. It has strong breaking ability of active load and no-load cable current and closing ability of short-circuit current. And can be equipped with lightning arresters and ground fault indicators according to user requirements.

Each ring network line in this series of products is equipped with a load switch or vacuum circuit breaker. Any branch circuit can be withdrawn and put into operation freely, and other ring network circuits will not be affected.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 fault circuit and hit the release of the load switch to open it. The fault circuit is isolated, thus ensuring the safety of the non-fault branch circuit. Supply continuity.

This product is widely used in 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 strong and durable. The live parts are fully insulated and fully sealed. If the flood-proof touchable cable head is used, it can also withstand floods and greatly improve the reliability of power supply. This product is widely used in distribution networks in urban industrial areas, residential areas, commercial centers, mining areas, airports, railways, wind power stations, switch offices and large enterprises such as steel, petroleum, chemicals, cement, etc., as well as other occasions. It is especially suitable for urban roads. The power grid transformation project can greatly save investment in electrical equipment and cables and improve power supply reliability.

Cable Branch Box With Vacuum Load Switch (Vacuum Circuit Breaker)

It is assembled using domestic high-quality vacuum load switches (vacuum circuit breakers), cleverly separated left and right incoming and outgoing lines, minimal structural design, and strongest cable configuration function, with up to 8 incoming and outgoing lines. This branch box not only retains the advantages of the traditional branch box, but also has some advantages of the ring main unit. It is an ideal equipment for urban network transformation. Small size, maintenance-free, good technical economy, high reliability, simple installation and convenient use.

The characteristics of the cable branch box with vacuum load switch are: there are three compartments in the box, one of which is sealed. The operating mechanism of the load switch is located directly in front of the branch box and can be operated manually or electrically. There are cable pile lines in the cable compartment. And the cable terminal, the cable terminal is connected to the load switch. The cable compartment can be protected by a fuse if the design requires it. The design is diversified and can realize functions such as telemetry, remote control, and remote signaling.
