Glass Bonded Mica Bushing Insulators

Bushing mica insulators can withstand 400 °C for very long time and even higher temperatures for short periods.

The conductive bar, integral with the insulating body, is normally supplied in silver-plated copper in order to guarantee maximum conductivity; on request it is also produced with other materials.

CTI index for evaluation of the resistance to tracking is higher than 600, means the maximum level considered by EN standards.
