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.
For the purposes of the parts of IEC60383. Overhead line insulators are divided into the four following types:
—line post insulators
—string insulator units, divided into two sub-types:
Cap and pin insulators
Long rod insulators
Insulators for overhead electric traction lines.
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.
The product standards include International Electrotechnical Commission, American Standard, German Standard, British Standard, Australian Standard and Japanese Standard.
