Case

GW5 (GT10)-126D/1600-40 outdoor AC high-voltage isolation switch is a type of GW5-126 switch that Tianan aimed at other companies, which has defects such as large operating force, broken bevel gear teeth, severe corrosion of metal materials, and out of control of the opening position. Developed after major improvements, it is a mature product recommended by the company for high-voltage distribution networks.
GW5 (GT10)-126D/1600-40 horizontal single-port outdoor AC high voltage isolating switch is suitable for power systems with AC frequency of 50Hz and rated voltage of 110kV. It is used for switching high-voltage lines under no-load conditions, and for electrically isolating electrical equipment such as high-voltage busbars, circuit breakers and other electrical equipment under maintenance from live high-voltage lines. It can also be used to switch small capacitive or inductive currents.
