DFW10-12 SF6 Hexaflouride Load Switch Cable Branch Box
Product Introduction
Overview:
DFW10-12SF6 Hexaflouride Load switch Cable Branch Box is using three-station SF6 load switch assembly, clever left and right out of the line, the smallest structural design, the strongest cable configuration function, access to up to 8 Road.
The splitter box retains the advantages of the traditional splitter box Point, but also has some advantages of ring network cabinet, is the ideal city network transformation equipment. Small size, maintenance-free, technical economy is good, high reliability, easy to install easy to use.
Cable with SF6 load switch The distribution box is characterized in that there are three compartments in the box, one of which is enclosed in a compartment, and the enclosed compartment is 路filled with microcharged sulfur hexafluoride gas, in which a group of load switches and load switches are operated The mechanism is located in the operation-driven compartment, the cable compartment has cable pile and cable terminal, cable terminal and load switch connection.
Structure:
The load switch in the compartmentally sealed load switch compartment is the movable contact of the turntable Type load switch, each load switch fixed on the axis of the symmetrical fan around the axis has three layers. The cable in the cable compartment is a three-phase cable, and each of the three cable ends is arranged in parallel with each other in parallel. The cable ends are directly connected to the cable pile lines, and the three cable stacks are parallel to each other. The enclosed compartment has a relief pipe.
