Cable Branch Box
Product Overview
European cable branch box is widely used in recent years in the power distribution system cable engineering equipment, its main features are two-way open door, the use of through-wall casing as a connecting busbar, with a small length, the cable arrangement is clear, three-core cables do not need to cross the advantages of a large span. The cable glands used are in accordance with DIN 7636. Generally, the rated current 630A bolted connection type cable glands are used.
Functional Characteristics
Fully insulated and sealed structure, no need for insulation distance, reliable guarantee of personal safety.
Dust-proof, flood-resistant, corrosion-resistant, maintenance-free, can be used outdoors as well as diffuse in water, applicable to any harsh environment.
Compact structure, small volume, easy installation, beautiful appearance, suitable for urban power grid renovation projects.
Flexible inlet and outlet lines, can be configured according to the need for multiple branch inlet and outlet lines to meet a variety of wiring requirements.
It can be equipped with charged display, short-circuit indicator and lightning arrester to improve the reliability and safety of power supply.
