DW26-15 series outdoor high voltage AC isolation switch, is a single phase hook rod operated isolation switch, the knife has a self-locking device. The isolation switch is suitable for the isolation of 12kV and 15kV overhead lines, and can be opened and closed under no-load operation. It is widely used with circuit breakers or load switches and provides safe visible fractures for the lines.
The isolation switch complies with GB 1985-2014 "High voltage AC isolation switch and ground switch", DL/T 486-2010 "High voltage AC isolation switch and ground switch" and other technical standards.
