Specifications
General
GW4A-40.5 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.
