Yuanky GW9 type outdoor high‑voltage disconnecting switch adopts single‑break vertical opened structure, each single‑pole unit is independently fitted on base frame, composed of post insulator, main conductive circuit and self‑locking device. It applies knife‑type contact structure to realize circuit breaking and making, compression springs are equipped on both sides of contact strips to obtain reliable contact pressure by adjusting spring height. The switch can be operated with insulated hook stick, and built‑in self‑locking mechanism keeps stable working status. This disconnector supports multiple installation ways such as post, wall, ceiling, cross‑beam and metal rack, installers shall keep contact blades downward when opening position. It covers rated voltage 10kV,15kV,24kV with multiple rated current specifications and long mechanical service life up to 2000 times for outdoor power distribution application.
