The type of cable distribution boxAddtime：2015/3/27 

1. common type  common type no switching equipment, wire connected together on the electrical, the same potential, suitable for tap or branch connection. Usually used to line number plus outlet called branches. Such as three branch cable branch box, its every phase have three equipotential connection point can be used as a second or two into a. Cable box containing U, V, W three-phase three-phase circuit, the same structure, aligned together.

2. advanced type < the advanced type contains switching equipment, is the common type of tap, the role of the branch and up power supply circuit control, conversion and change the operation mode. The switch fracture generally separates the cable circuit into the inlet and outlet side, and the potential can be different. Switching equipment itself has a larger volume, so the shape and the size of the advanced type is relatively large, generally high 1.4 to 1.8m, the depth is about 0.9 ~ 1.0 m and a length according to the number of switching devices and, between 1.0 to 2.4m. Body shape is similar to an outdoor box type transformer, box shell has a plurality of movable door, the gate is for switch equipment operation, some are for cable connection device installation and construction or maintenance of.
