1. Product overview
This product is using sulfur hexafluoride load switch or vacuum switch as a control switch (can also not be installed), using touchable shielding silicone rubber cable connector, with strong load and no-load cable current breaking ability and short circuit current closing ability, and can be equipped with lightning arrester and ground fault indicator according to user requirements.
Load switches or vacuum short-circuits can be installed on each ring network connection line in this product, and any branch circuit can be freely exited and put into operation, while other ring network circuits are not affected. A fuse can also be installed on the load switch to quickly disconnect the fault circuit, and hit the trip of the load switch to open it, and the fault circuit is isolated, so as to ensure the continuity of power supply of the circuit of the fault branch.
2. Product use
DFW-12 cable distribution box is widely used in relay distribution and power distribution of power system. It is an important electrical equipment for outdoor cable collection and distribution, and the distribution box is divided into ordinary cable distribution box and cable distribution box with switch. It can also be divided into ordinary type and flood protection type according to the sealing level. It is widely used in cities and areas where industrial and mining enterprises are concentrated. It is the first choice product to realize the cable transformation of urban power grid and realize fast power supply of ring network.
