Description
GW16 series disconnector adopts single-column single-arm vertical telescopic structure, which is mainly composed of base, insulator, conductive system, operating mechanism, etc. The disconnector is operated by CJ11 motor operating mechanism for opening and closing. The attached ground switch is mainly composed of ground switch system and operating mechanism, and each group of ground switches is operated by a CJ11 motor operating mechanism for opening and closing.
Main Features
Simple and compact structure, small footprint.
Strong product flow capacity, long mechanical life.
Optimized spring design, light and smooth operation.
High seismic performance, can resist nine degrees of earthquake intensity.
The layout is flexible, convenient for users to choose.
