| Place of Origin:Wenzhou Zhejiang China |
| Brand Name: SHENGSU |
| Model Number: GW4-252 |
| Rated frequency: 50/60Hz |
| Rated current: 2000A |
The complete disconnecting switch consists of GW4-252(D)(W) type disconnecting switch body, CS14G or CS17G type manual operating mechanism,transmission accessories, etc. it can also be equipped with CJ6 type and other electric mechanisms.
The disconnecting switch is double-post horizontal opening type. Each single pole part is composed of base, post insulator, an outlet seat and a contact.The two post insulators are installed parallel to each other on the bearings at both ends of the base and are perpendicular to the base.The main conductive parts are respectively installed above the two insulators and rotate about 90° with the post insulators. The bearing seat of the disconnecting switch is designed as a fully sealed structure, which can prevent the jam caused by dust, moisture, and harmful gas entering the bearing seat,the bearing seat is equipped with thrust ball bearings and radial ball bearings to separate the gravity and level of the disconnecting switch.

Using the environment conditions
a. The altitude does not exceed 1000m.
b. The ambient air temperature: Maximum+40°C; Minimum: -30°C,Paramos-40°C.
c. The wind pressure does not exceed 700Pa. (corresponding to 34m/s wind speed).
d. The earthquake intensity does not exceed 8 degreese.
e. The working situation hasn't frequent violent vibration.
f. The installation site of ordinory type isolator should be kept away from gas, smoke chemical deposition, salt-spray fog, dust and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator.
g. Pollution-proof type isolalor is applying to severe filthy conduction area; however, it shouldn't be any explosive matters and matters causing fire.
