Product Details
Product description
VS1 type VCB consist of operating mechanism and arc-extinguish chambers in front-back arrangement, its main conductive circuit is floor model structure. The vacuum arc-extinguish chamber is fixed in a vertical cannular insulation column made of epoxy resin by APG technology, therefore with high anti-creepage function. Such structure design greatly reduces the accumulation of dusts on the surface of vacuum arc- extinguish chamber, it not only can prevent the vacuum extinguish chamber from outside influences, but also can ensure to present high resistance state against the voltage effect even in warm-wet climate or heavy pollution environment.
