Structure feature:
GW9-12(W) disconnect switch is single type
1. This series switch have normal and anti-pollute two difference models, it composed of frame,support insulator,  with power part and operating mechanism.
2. Each pole have two pieces blade, there is press spring near press, there is a support structure on the blade, it can be locked after closing, so it will not be closing by itself under any condition, under normal or short-circuit condition, it can ensure the reliable performance of dynamic and thermic stability

Normal Service Conditions:
1 The altitude does not exceed 1000m.
2 The ambient air temperature: Maximum+40°C:Minimum: General Area-30°C, Paramos-40°C.
3 The wind pressure does not exceed 700Pa.
4 The earthquake intensity does not exceed 8 degrees.
5 The working situation without frequent violent vibration.
6 The installation site of ordinary type isolator should be kept away from gas, smoke chemical deposition, salt-spray-fog, dust and other and corrosive maters that affect seriously insulation and conuction capability of the isolator.
7 Pollution-proof type isolator is applies to severe filthy conduction area
8 It shouldn't be any explosive matters and matters causing fire.

Product Description
FN5-12 Series High Vacuum Indoor Load Break Switch
It is designed and developed by our own company by bringing in international advanced technology, considering our own country's specific power supply. It performances meet IEC420 AC H. V. Load Switch with Fuse(1990 Edition) and GB3804 3-63kV AC H. V. Load Switch after strict test and long - time operating. Compared to the product of the kind in the foreign country, its technical parameter has reached the international level with the featrues of small volume and light weight. Can be used in package substation and ring network cebin. It is used widely in 12kV distribution network to protect the equipment against working wihout phase. 
The success of the product fills the domestic gap, with functions of switchisolating and earthing. 
Use
It is used in the network of 50Hz rated voltage 6-12kV for breaking load, over-load and short-circuit current. It is equipped with CS6-I type handle operating mechanism. It is for the CS handle mechanism. 
Service condition
1. The altitude does not exceed 1000m. 
2. The ambient air temperature: Max.: +40. Min.: -10. 
3. The relatire humidity of air diaily average ≤ 90%, monthly average ≤ 95% (temperature: 25 ). 
4. The ambient air should not be obviously polluted by corrosivity and the flammability gas. Etc. 
5. The working site is without frequent violent.
