Product Introduction
SF6 Switch Cable Distribution Box:
It adopts three-station SF6 load switch assembly, clever left and right inlet and outlet settings, minimal structural design, strongest cable configuration function, and the inlet and outlet lines can be up to 8 ways. The tap changer not only retains the advantages of traditional tap changer, but also has some of the advantages of ring network cabinet, which is the ideal equipment for urban network transformation. Small size, maintenance-free, good technical economy, high reliability, simple installation and easy to use. The cable transfer box with SF6 load switch is characterized by: three compartments in the box, one of which is closed, the closed compartment is filled with micro-pressurized sulfur hexafluoride gas, which has more than one set of load switches, the operating mechanism of the load switches is located in the operation drive compartment, the cable compartment has a cable staking line and cable terminals, the cable terminals are connected with the load switches. The load switch inside the compartment-enclosed load switch compartment is a turntable dynamic-static contact type load switch, and there are three layers of symmetrical sectoral surfaces fixed to the winding shaft on the rotating shaft of each load switch. The cables in the cable compartment are three-phase, three cable terminals in each group are distributed diagonally below each other in parallel sequence, each cable terminal is vertically connected to the cable staking line, and the three cable staking lines are connected to each other.
