Insulator classes

Overhead line string insulators are divided into two classes according to their design.
Class A: an insulator or insulator unit in which the length of the shortest puncture path through solid insulating material is at least equal to half the arcing distance. An example of a class A insulator is a long rod insulator with external fittings.
Class B:an insulator or insulator unit in which the length of the shortest puncture path through solid insulating material is less than half the arcing distance. An example of a class B insulator is a cap and pin insulator.

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.

Pin insulator

A rigid insulator consisting of an insulating component intended to be mounted rigidly on a supporting structure by means of a pin passing up inside the insulator. The insulating component may consist of one or more pieces of insulating material permanently connected together. The fixing of the insulating component to the pin can either be separable or permanent (pin insulator with integral pin).
