Line post insulator 20kv

Line post insulator 20kv is one of outdoor insulators, and can be divided into porcelain insulator and polymer insulator used for distribution power lines.

Line post insulator 20kv

According to insulator application, the basic functions for outdoor insulators
◆ Mechanical support conductors or bus wires
◆ Insulation with structural elements

If the outdoor insulators lost their performance, the main reasons are
◆ Insulator body breakdown
◆ The surface of insulators is flashover

Line post insulator 20kv is one of line post insulator, according to insulator end fittings, the types of these insulators
◆ Tie top insulators
◆ Clamp top insulators
◆ Gain base type insulators

Nowadays, porcelain insulators should be coated RTV silicone rubber coatings or other polymer materials coating to increase creepage distance. The features of these insulators
◆ Providing long service life
◆ Good hydrophobicity performance
◆ Big creepage distance to improve anti-polluted resistance

Line post insulator 20kv is made from high strength porcelain used on the distribution overhead lines. The insulators made from polymer can be used in any polluted areas.
