10KV High Voltage Cable Branch Box

10KV high voltage cable branch box

Descriptions

10KV high voltage cable branch box is a kind of power equipment, which is mainly used in the urban power grid, especially when the independent load distribution is concentrated, it can realize the connection of multiple branches of the cable. It has the function of cable tapping and transferring, through the trunk large cable outlet, and then use the branch box near the load to divide the trunk cable into a number of small area cables, from the small area of the cable access to the load. This wiring method is widely used in street lamp power supply, small user power supply and other scenarios.

In the 10kV power supply system of high-speed railway, 10KV high voltage cable branch box also plays an important role, which can realize the intermediate connection and branch connection of the cable when the power supply is long-distance, so as to ensure the reliability of power supply.

Product structure Characteristics

The main advantages of 10KV high voltage cable branch box include fully enclosed, fully protected, pollution resistant, corrosion resistant, and can adapt to all-weather operating conditions and different working environments.

It is small in size, occupies a small area, and has a beautiful appearance, which will not damage the appearance of the township. The conductor connector in the branch box is crimped to facilitate the entry and exit of the equipment.

In the application, the branch box can have up to 6~8 branch inlet and outlet lines, which can complete the multi-channel power supply of the community, and provide technical support for shortening the power supply radius and reducing line loss. In addition, the cable branch box can be equipped with a variety of protection devices, such as power indicators, fault indicators, silicone rubber fully insulated piercing arresters, etc., to ensure safe operation.

With the cable network ring network power supply, it can be equipped with SF6 and other ring network load switches to meet the requirements of partial power outage maintenance, complete regional power outage maintenance, narrow the power outage plan, and do not affect the operation of the main network.

How to Choose a cable branch box

When choosing a cable branch box, its material, structural characteristics and application precautions should be considered. For example, the cable branch box made of silicone rubber material has the advantages of good sealing performance, moisture-proof, waterproof, anti-aging, etc., and is non-toxic, which is beneficial to environmental protection. The difference between live touchable and live non-touchable cable glands should also be considered when choosing, as well as their reliability and economy in actual operation. When installing and using the cable branch box, it is necessary to pay attention to check whether the grounding wire of each branch cable is connected with the grounding terminal of the box body, and the box shell needs to be directly connected with the ground grid or have an obvious connection address. After the installation is completed, the cable assembly should be tested in accordance with the specified experimental standards and conditions to ensure safe and reliable operation.
