Introduction

GW9-24 (W) series Outdoor H.V. disconnect switch is single pole structure, which is used for opening or closing circuits under the voltage but no-load condition in 24kV outdoor electrical system. It has fixed draw hook and self-locking device, and effect operation with insulating hook-stick. Further more, Anti-pollution type switch can effectively solve flash due to pollution during the operation of disconnect switch so as to satisfy the requirement of users in badly polluted area.

 

Working Conditions

1.Altitude above sea level: 1000~3000m;
2.Ambient temperature:  -25 ~+40℃;
3.Earthquake intensity: ≤8 degree;
4.Occasions without frequent and severe vibration, without matters which will badly influence the insulation and conductivity of disconnect switch, such as gas, steam, chemical sediment, salt fog, dust, and the other explosive and corrosion matters;
5.Anti-pollution type switch is suitable for heavy polluted area but without matters which will incur fire and explosion.
