GW7F series disconnector is the three colums,double break,horizontally reverse type structure,applied to the electrical system of rated frequency 50Hz or 60Hz, used in HV lines transfer in free of load condition and electric disconnection for maintenance of HV busbar,circuit breaker and live HV lines,etc.
GW7F Series HV AC disconnector is composed of three poles. Each pole is 3 columns structure, consisting of pedestal, pillar insulator, main blade, static contact-head of main blade, etc. Three pillar insulators separately are vertically installed on pedestal. The main blade is installed on the top of middle pillar insulator. Other 2 static contact-head are installed on the top of side pillar insulator. When main blade on the top of middle pillar insulator
horizontally rotates for 70 degree, moving contact will insert into static contact then reverse for 45 degree, which makes static contact-fingers clamp the moving contact to finish one blade closing operation. For opening blade operation, vice versa.
