RDFW series high -pressure cable branch box

The RDFW series cable branches are outdoor high -voltage electrical equipment with a rated voltage of 12kV/50Hz and a rated current of 630A, which are used for connections and distribution in power and cable and urban power supply systems. This product has the characteristics of high security factor, diversified combination, and wide range of scope, which can meet the user's design requirements and the solution of customer design schemes, and provide technical solutions that satisfy customers.

Structural features

The RDFW series branch box uses high -performance load switch with internal inflatable SF6 insulating gases and accessible shielding silicone rubber cable joints. It has a strong capacity and air load load and air load cable current. Configure the corresponding minefarers and ground fault indicators according to the user's requirements. This series is equipped with a load switch or a vacuum circuit breaker on each ring network. Any branch circuit must be freely exited and put into operation, and other ring network circuits are not affected. The fuse can also be installed on   the load switch. When a short -circuit failure occurs in a branch circuit, the fuse on the load circuit quickly disconnects the fault loop, and the off -load switch of the load switch is divided. In this way, the power supply continuity of the branch circuit is guaranteed.
