gis substation Transmitter for Ultra High Voltage

gis substation Transmitter for Ultra High Voltage

GIS have compact structure, longer lifespan and low maintenance cost. Of the two major types of GIS, high voltage and medium voltage, the former accounts for major market share as high voltage gas insulated switchgears are efficient to transmit electricity at high voltage, extra high voltage, and ultra-high voltage level.
