China Gw9 Series Polymer High Voltage Disconnect Switch Outdoor with Insulator, Find details about China Disconnect Switch, Isolation Switch from Gw9 Series Polymer High Voltage Disconnect Switch Outdoor with Insulator
GW9 type outdoor high-voltage isolating/disconnect switch
Description:
The"GW9-10G" type of outdoor high voltage isolator switch is the high voltage switch equipment of single-phase AC50Hz. The product is suitable for power system with rated voltage 10kV to make or break power supply under circumstances of voltage and no-load. The isolator is adopted isolated(disconnector) rod to operate.
| 1. Scientific design and innovative structure |
| 2. Contacting points distribute on two planes, small operating moment, and release pressure to small and easy adjustment |
| 3. Improved driving and conducting part |
| 4. Column moving contact that can decrease operating strength and ensure reliability of circuit conduction |

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