GN19-12C type disconnect switch is an indoor wall-mounted high-voltage distribution device widely used in 50Hz AC power systems, rated voltage 12kV. It is mainly used for switching circuits under no-load conditions to achieve reliable isolation between electrical equipment and power supply. It supports three-phase parallel installation or wall installation in special scenarios
GW4 series disconnect switches are outdoor high-voltage switchgears widely used in power systems, mainly for voltage isolation and safety protection in electrical equipment maintenance.
Isolation switch GW1 is a switching device mainly used for 15kV transmission lines, designed for “power supply isolation, switching, connection and disconnection of small current circuits”, without arc suppression function.
