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 |

| 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. |
