<strong>General</strong> characteristics<br />
The PTC bushings can be used as a fixed part in medium voltage<br />
inlet for oil or SF6 insulated devices, such as transformers or switchgears.<br />
They are equipped with a connection for the reading of low voltage by a light signal box.<br />
Application<br />
For indoor application, suitable for vertical or horizontal installation.<br />
