Isolator High Voltage Disconnect Switch145kV For Breaking Or Connecting HV Lines

145kV Outdoor Isolator Hv Disconnect Switch For Breaking Or Connecting HV Lines


GW4A-126 D(W) isolating switches are kinds of outdoor HV electricity transmission equipments at three phase AC frequency of 50Hz/60Hz. It is used for breaking or connecting HV lines under no loads so that the power lines can be changed and connected and the way the electricity runs is changed. In addition, it can be used to exerise safe electrical insulation for such HV electric apparatuses as bus and breaker.
This product has two insulators with horizontal center breaks. It is openable in the middle and accessible to the grounding switch on one side or two sides. The isolating switch adopts CS14G or CS11 manual operating mechanism ro CJ2 motor based operating mechnism to realize the tri-pole linkage. The grounding switch adopts CS14G manual operating mechanism to actualize tri-pole linkage.
