Product description:
the main designer after two years, committed to the air insulation, simple structure and low cost as the goal, the use of mature technology, set the collective wisdom of domestic experts cleverly designed cabinet width 375mm rated current 630A-1250A, breaking current 20KA- 25KA, with a visible fracture of the vacuum switchgear. Replace the sulfur hexafluoride load switch, reduce the amount of epoxy resin, improve the ability to segment and transfer current is our goal.
