三、户外高压隔离开关
Out-doors high voltage disconnector
说明（Explanation）：
GW9-12型户外高压职责离开关是单相交流50HZ高压开关设备，用于10KV的电力系统中，作为有电压无负载的情况下接通或分断电源使用。
本隔离开关用绝缘棒进行操作。
The “GW9-12”type of outdoor high voltage isolator switch is the high voltage switch ewuip ment of single phase AC 50HZ,The product is suitable for power system sithrated 10KV to make or break power supply under circumstances of with voltage and nomload.
The isolator is adopts isolated hook rod to operate.
正常使用条件（Normal service conditions）:
