<strong>General</strong> characteristics<br />
Post <strong>insulators</strong> made of epoxy <strong>resin</strong> (EP UL94V0) or<br />
polyesther reinforced with fiberglass (UP FG), suitable for<br />
indoor application with internal metal fitting. These <strong>insulators</strong><br />
are particularly suitable to be used as single supports for<br />
bus-bars, fuses <strong>and</strong> for other equipment.<br />
Application<br />
For indoor applications with working condition at max.<br />
operating temperature of 160 ºC (epoxy <strong>resin</strong> - EP UL94V0)<br />
<strong>and</strong> 130 ºC (polyesther - UP FG)<br />
Working voltage<br />
From 0,4 up to 2 kV<br />
