12kv Outdoor High Voltage Isolating Switch Disconnecting AC Switch
- Type:
- High-voltage
- Origin:
- Zhejiang, China
Overview:
The isolating switch is of a unipolar type, and the three poles can be connected by a connecting rod into a three-pole type that can be linked. It is equipped with CS11 or CS8-6D manual mechanism. CS17 is used for the isolating switch with double grounding device. (The electric mechanism can be equipped as needed).
The isolation switch has reasonable structure and flexible operation: it can be used for single pole or three poles, and the installation is convenient: the touch knife is opened, and the insulation is safe and reliable. It can also be grounded or double grounded according to user needs.
