Product description
This series of cable branch boxes are suitable for outdoor distribution networks with AC 50Hz, rated voltage 12kV,
and cable inlet and outlet lines. They are widely used in industrial parks, residential quarters, commercial centers,
mining areas, airports, railways, ports, power stations, and other power distribution networks. , Especially suitable
for urban power grid transformation projects. have:
1. Fully insulated, fully sealed and maintenance-free. Reliable personal safety protection.
2. Simplify the urban cable network system and save investment.
3. Outdoor type, dust-proof, moisture-proof, anti-flood, corrosion-resistant, strong environmental adaptability,
flexible combination, access lines from two to eight, can meet various connections
Line requirements.
4. Small size, compact structure, beautiful appearance, simple installation, maintenance-free; and there is a live
display, can be equipped with a short-circuit indicator, and can be equipped with a lightning arrester.
5. Small footprint, low height, beautiful appearance, can be coordinated with the surrounding environment; flexible
and diverse wiring schemes, installation and operation are extremely convenient.
6. The 200A cable head can be plugged and unplugged under load and has the function of an isolating switch. It
can be installed with a short-circuit fault indicator to quickly determine the fault location.
7. Any combination of load switches or circuit breakers and cable joints can be used to improve the flexibility of line
operation, maintenance and overhaul, reduce line power outage time, and improve power supply reliability. It can
replace part of the ring network cabinet or opening and closing station, reducing the overall cost of the system.
