Description
GW9-12-15KV (W) type outdoor high-voltage disconnector is suitable for power systems with AC 50Hz and rated working voltage of 10KV to cut off and close single-phase or three-phase circuits with no load and voltage.
GW9-12-15KV (W) series outdoor high-voltage isolating switch is a high-voltage switchgear with unipolar structure. It is used for opening and closing circuits when there is voltage and no load in the outdoor 12 kV line network. Equipped with fixed hooks and self-locking devices, flexible and reliable, and operated with insulating hook rods. Among them, the anti-pollution outdoor high-voltage isolating switch can meet the requirements of users in severely polluted areas.
