Application
GW9-12 Series Outdoor Single-pole Isolating Switch can be used in high voltage transmission and distribution line of 50Hz and 12Ky for making and breaking the single phase or three-phase line with zero-load and voltage.
Normal Working Conditions
1. Upper limit of ambient air temp, is +40ºC , lower limit is -300C for general regions and -40'C for high and cold regions;
2. The height above sea level not exceeding 2000m;
3. Wind pressure not exceeding 700 Pa (equivalent t0 34m/s);
4. Earthquake: 3.1 d;
5. Place without and inflammable or explosive danger, conductive, chemical corrosion or severe vibration;
6. The ice covering not exceeding 10mm;
7. Air pollution degree: III .
Structural Features
The isolating switch is composed of base, bar type isolator, conducting strip, and fuse hook.
The conducting strip is mounted with fuse hook. After switchingin, it will self-lock, and not automati-cally switch out under the deadweight or electric actuaing force. The isolating force. The isolating switch is designed to be single-pole structure and can stiwchin/out by using hook bar and separately control each phase of 3-phase circuit.
The switches with HRC fusemeet with the following data:
