The cable branch box facilitates the maintenance and repair of the lines.

In order to facilitate the maintenance and inspection of the lines, improve the flexibility of operation modes, and reduce the downtime of the lines, the cable branch box can connect the load switch with related cable joint accessories, becoming a cable branch box with a switch. This switch can directly cut off the load current, enhancing power supply reliability. With full edge, full sealing, and full working conditions, it allows for regional power outages for maintenance without affecting the operation of the main network, and can replace some ring network cabinets, thereby reducing project costs.

What benefits can using a cable branch box bring us?

The cable branch box is a type of cable engineering equipment that has been widely used in distribution network systems in recent years. Its main features include bi-directional doors and the use of wall sleeves as busbar connections. It has obvious advantages such as short length, clear wiring, and no need for large-span three-core cable interconnections. The selected cable connector complies with DIN47636, and a 630A bolt-rated fixed splicing cable joint is generally used.

The branching and connection of cable junction boxes.

The arrival of the electrical era has made our world brighter. With the development of distribution network wiring, if the independent load capacity is small but concentrated, cable branch boxes can be used to connect multiple branches of cables.

The box-type substation has improved work efficiency.

Box-type substations, which are widely used currently, consume a large amount of electrical energy after long periods of operation, leading to a decrease in efficiency. The newly developed reactive power compensation technology can save reactive power, thereby reducing energy consumption and improving efficiency.

Fire protection requirements for box-type substations

The busbars of the box-type substation are enclosed with insulating materials. According to regulations, when the height of uninsulated bare conductors above the ground is greater than 2.3m, protective devices of at least IP2X level should be installed. The height of the box-type substation generally does not exceed 2.5m. In addition, the equipment inside the box-type substation is installed compactly and densely, with a small distance between the remaining operating and protection passages, requiring the use of fully enclosed busbars.
