Insulator types

For the purposes of the parts of IEC60383. Overhead line insulators are divided into the four following types:
—pin insulators
—line post insulators
—string insulator units, divided into two sub-types:
Cap and pin insulators
Long rod insulators
Insulators for overhead electric traction lines.

Insulating material

The insulating material of overhead line insulators coved by this parts are:
—ceramic material, porcelain
—annealed glass, being glass in which mechanical stresses have been relaxed by thermal treatment.
—toughened glass, being glass in which controlled, mechanical stress have been included by thermal treatment.

Insulator string

One or more connected string insulator units intended to give flexible support to overhead line conductor and stressed mainly in tension.
