Summary
The cable distribution box is a excellent product to solve the problem of too massive brunches. It has the feature of fully insulated and fully sealing, which can decrease the fault ratio in the power supply line.
The distribution is simple, convenience and flexible. In some situations, it can replace the ring main unit. It also can be put into water and underground which suit to the place of business center, industry garden, cities and so on.According to the structure and the kind of cable connector, it can be divided as: American cable distribution box, European cable distribution box and distribution box with switch.
