High voltage line pin type porcelain insulator: High-voltage line pin porcelain insulators are mainly used for insulating and supporting conductors in overhead transmission lines. According to the rated voltage, it is divided into five grades: 6, 10, 15, 20 and 35kV. The pin insulator is composed of porcelain and steel feet (or screw sleeves), and the porcelain and steel feet (or screw sleeves) are connected with Portland cement cement as a whole. The surface of the porcelain is white or brown, and the surface of the steel foot is hot-dip galvanized.
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).
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.
