Product name:
GW -12/24/40.5 Outdoor HV Disconnect Switch
Summary
GW -12/24/40.5-630-20(25) outdoor AC high voltage disconnect switch (disconnec t switch f or short) is used to open and close circuit with voltage but no-load 50/60Hz, 12/24/40.5kV power system, The anti-pollution type can be used in the serious pollution area. Three pole linkage, good synchronous performance. IEC62271-103: High voltage switches.
NOTE: The model of the 24kV Outdoor HV Disconnect Switch is GWHY2-24.
