Product description

Summary
    KWDF10 series high-voltage cable branch box (also known as outdoor cable branch box) is outdoor high-voltage electrical equipment with rated voltage of 12kV or 24kV and rated current of 630A, which is used for connection and tapping of power cab

Structural Features
    This product is internally equipped with sulfur hexafluoride load switch and touchable shielded silicone cable connector, which has strong opening capacity of active load and no-load cable current and closing capacity of short circuit current, and can be equipped with lightning arrester and ground fault indicator according to user requirements. Each ring network cable in this series is equipped with a load switch or vacuum circuit breaker. Any branch circuit can exit and put into operation freely, and other loop network circuits will not be affected. A fuse can also be attached to the load switch. When a branch circuit has a short circuit fault, the fuse on the branch circuit can quickly disconnect the fault circuit, hit the release of the load switch to open it, and the fault circuit is isolated, thus ensuring the power supply continuity of the non-fault branch hoist.

The Product Meets The Standard
GB3804-2004 3.63kV-40.5kV high-voltage AC load switch

GB311.1-1997 Insulation Coordination of High Voltage Transmission and Transformation Equipment

GB11033.2-1989 Basic technical requirements for power cable accessories with rated voltage of 26/35kV and below

GB4208-2008 Degrees of Protection Provided by Enclosures

GB11032-2000 AC gapless metal oxide arrester



Adaptation Place
    This product is widely used for cable tapping in 10kV or 20kV power systems. Its connection mode is simple, flexible, convenient, safe and reliable. The cabinet body is made of 2mm stainless steel plate, which is solid and durable. The live part can be fully insulated and sealed. If the flood-proof touchable cable head is used, it can also resist the flood and greatly improve the power supply reliability. This product is widely used in urban industrial communities, residential communities, commercial centers, mining areas, airports, railways, wind power stations, switching on and off all large enterprises such as steel, petroleum, chemical, cement and other occasions, as well as distribution networks. It is especially suitable for urban road power grid reconstruction projects, which can greatly save investment in electrical equipment and cables, and improve power supply reliability.
