375 Air Insulated Ring Network Cabinet

We manufacture, export and supply 375 Air Insulated Ring Network Cabinet in Cangzhou, Hebei, China. The main designer after two years, is committed to air insulation, simple structure and low cost as the goal, the use of mature technology, set the wisdom of the collective wisdom of domestic experts designed cabinet width 375mm rated current 630A-1250A, breaking current 20KA- 25KA, a vacuum switch with a visible fracture. Replacement of sulfur hexafluoride load switch to reduce the amount of epoxy resin to improve the segment capacity and transfer of current is our goal.
