Single Phase Disconnecting Porcelain Isolate Switch

Model GW9-27/600

An electrical device that, when no current is present, reliably disconnects certain areas of a high-voltage electrical network. The configuration of transformer substations and switching points can be made simpler by using isolating switches, either by themselves or in conjunction with high-speed short-circuiting devices. Additionally, high-voltage circuit breakers can be removed, saving money.
