CGVB-05 Vertical Break Disconnector up to 550 kV

GE’s CGVB-05 vertical break disconnector is designed to reduce phase spacing to a minimum. The jaw end of the switch is supported by one fixed insulator. The hinge end consists of two insulators, one fixed, the other rotates to open and close the switch. The double movement of the aluminum blade ensures high short circuit rating and excellent ice breaking capabilities. The CGVB-05 is designed to be maintenance free with factory sealed bearing housings and counter balancing springs. If you are interested in porcelain insulator,composite insulator for the disconnector breaker, please no hesitate to contact changsha rich company for reasonable price: www.hncmec.com
