High voltage pin type insulators

High voltage pin type insulators are one part of overhead distribution lines, and they are directly related to the safe and stable operation of the grid. This article mainly talks about insulators’ important role in overhead distribution lines.

High voltage pin type insulators

The function of high voltage pin type insulators
◆ Support the conductors
◆ Live parts and earth insulation

For ensuring the insulator quality, the insulators are manufactured with some requirements
◆ Standards Insulation resistance
◆ Mechanical and electrical resistance
◆ Weather resistance
◆ Heat resistance
◆ Good self-cleaning properties, self-cleaning ability
◆ Suitable for arid, dry areas, sand and large climatic conditions

High voltage pin type insulators can be divided into
◆ Porcelain pin insulator
◆ Polymer pin insulators
◆ Glass pin insulator

As one of insulator manufacturers in China, Orient mainly produces porcelain insulators and polymer insulators including high voltage pin type insulators, transmission and distribution power line insulators.
