KYN28A-12 (GZS1-12Z) armored metal middle closed switching equipment

It is the new type of products developed on the basis of advanced technology from abroad and it can replace the out of dated metal closed switching equipment. The product has the following advantages: the shell is made of the aluminum zinc plate which was multi bending by CNC machine tool and formed by the assemble bolts and therefore has high mechanical strength, and effectively guarantees the beauty and tidy of the products. The door applies the spray coating and has high resistance of impulse shock and corrosion. The product has P4X protection level. The main switch cabinet can be equipped with the ZN63 vacuum circuit breaker, C3 series fixed load switch cabinet, and it can get on net with the staff with the help of communication interface to remote control and telemetry. The bare conductor insulation distance is more than 125mm, and the composite insulation is more than 60mm no matter whatever breaker applies. The breaker is long life, high parameter, maintenance-free and small size.
