a> The disconnector switch adopted three-position design, which theoretically avoid the maloperation completely. bx Using the contact design which is advantageous to the grounding connection, so that the grounding closing speed reached >4.2m/s. c, - High-performance disc spring from Mubea Germany guarantee the stability of contact pressure d. - The transmission gap of Spindle driven rotation isolation is small, which ensures reliable ground distance and isolating distance a. Simple circuit design, uniform electric field distribution structure, no need for more complex insulation, spacious gas box space which meets the good heat convection b. b. Use recyclable and reusable environmental thermoplastic materials with high mechanical strength and good heat-resistance. Replace epoxy casting vacuum interrupter skeleton with one-injection molding three-phase integral vacuum interrupter frame. The design is featuring simple structure, uniform electric field strength, outstanding insulation performance, high production efficiency, less adjustment, easy assembly and many other advantages. a, The motor, auxiliary switch, release, travel switch of main switch mechanism can be replaced at any time, so that the products are convenient to be repaired bx Double spring precision transmission design with function of reclosing c, In order to meet the latest procurement standards of State Grid, the main switching mechanism is equipped with automatic counting function d, All transmission parts are made of high-quality steel and quenched steels
