The model and meaning of DFW series outdoor cable branch box.
Features:

Complete insulation, complete seal, maintenance free.
Simplify urban cable network system, saving investment.
Outdoor type, anti-dust, moisture proof, anti-flood, resistant to corrosion, strong environmental applicability, flexible combination and meeting various connection requirements.
Small volume, compact structure, beautiful appearance, easy installation. Equipped with display, short-circuit indicator and arrester can also be added.
Small occupation, low in height, coordinate with surroundings, flexible connection program, convenient installation and operation.
2000 A cable end can be pl ed & unpl ed with load. Meanwhile, it has the function of disconnecting switch and it can be equipped with short-circuit fault indicator to locate the fault point quickly.
It improves the flexibility of line operation, maintenance & overhaul, reduces line outage time and improves power supply reliability by the arbitrary combination of load switch with cable end or the combination of circuit breaker with cable end. It can replace part ring main units (RMUs) and switching stations, which can reduce the comprehensive cost of system.
