Lightning Arrester & Porcelain Insulator

Porcelain Arresters and Insulators, 6 kV to 66 kV

This section groups the high-voltage side of the Doto range: porcelain surge arresters that clamp lightning and switching overvoltages on distribution lines, and pin, post and suspension insulators from 6 kV to 66 kV that support and isolate live conductors. Creepage profiles are selected for polluted and coastal environments, and metal fittings are hot-dip galvanised.

Voltage class, creepage distance and mechanical load are the three numbers that define the right part. Send the system voltage, pollution level and conductor load and we will match the insulator or arrester and quote with test certificates.
