The conductor connector in the cable branch box adopts crimping method, which is convenient for installation and flexible for incoming and outgoing lines. There can be up to 6-8 incoming and outgoing lines in the application, which can realize multi-channel power transmission in the community, providing technical support for deepening the load center, shortening the power supply radius and reducing the line loss. At the same time, the cable branch box can be equipped with power indicator, fault indicator, silicon rubber fully insulated plug-in arrester, mechanical programmable lock, grounding switch, etc., to ensure the safety of operation, maintenance and management. With the power supply of cable network ring network, SF6 and other ring network load switches can be configured. Under the condition of not affecting the operation of the main network, the local power outage maintenance requirements can be met, and the regional outage maintenance and the scope of power failure can be reduced. At the same time, the ring network cable branch box can realize the power supply of the ring network, laying a foundation for the future adjustment of 10kV line network structure.
Product structure features and performance:
It is fully sealed, fully protected, pollution resistant and corrosion resistant, and can meet the outdoor operation conditions all day and can adapt to different working environment.
Cable branch box belongs to the floor type box, which is small in volume and small in area. If some of the boxes occupy an area of 0.65m2 and SF6 switch, the floor area is only 1.45m2; the appearance of the cable branch box is beautiful and will not cause damage to the appearance of the town.
The conductor connector in the branch box adopts crimping mode, which is convenient to install, flexible in and out of the line. In the application, there can be up to 6-8 branch incoming and outgoing lines. It can realize multi-channel power transmission in the cell, which provides technical guarantee for deepening the load center, shortening the power supply radius and reducing the line loss. At the same time, the cable branch box can be equipped with power indicator, fault indicator, silicon rubber fully insulated plug-in arrester, mechanical programmable lock, grounding switch, etc., to ensure the safety of operation, maintenance and management.
With the power supply of cable network ring network, SF6 and other ring network load switches can be configured. Under the condition of not affecting the operation of the main network, the local power outage maintenance requirements can be met, and the regional outage maintenance and the scope of power failure can be reduced. At the same time, the ring network cable branch box can realize the power supply of the ring network, laying a foundation for the future adjustment of 10kV line network structure.
Installation, use and precautions:
At present, there are many kinds of 10kV outdoor cable branch boxes in China. Therefore, the installation and construction of 10kV cable branch boxes become very important. Whether the operation method of the installation and connection process of cable branch box and cable joint is correct, whether the installation process of cable head is familiar, the sequence of the combination of internal components and cable joint parts of cable branch box, whether to operate according to the installation specification provided by the manufacturer, etc., will directly affect the service life and normal operation of cable branch box.
Before the operation of cable branch box, it is necessary to check whether the grounding wire of each branch cable is connected and fastened with the grounding terminal of the box. At the same time, the case shell must be directly connected with the ground grid or have obvious grounding point.
After the installation of cable branch box, the components of cable must be tested together according to the relevant test standards and conditions.
