High Voltage Insulator

Introduction

The purpose of the insulator or insulation is to insulate the electrically charged part of any equipment or machine from another charged part or uncharged metal part. At lower utilization voltage the insulation also completely covers the live conductor and acts as a barrier and keeps the live conductors unreachable from human being or animals. In case of the high voltage overhead transmission and distribution the transmission towers or poles support the lines, and Insulators are used to insulate the live conductor from the transmission towers. The insulators used in transmission and distribution system are also required to carry large tensional or compressive load.

Composite insulators have

Composite insulators have

Early years of the insulator used for telegraph poles, with the development of technology, and slowly developed in the high-pressure wire to connect one end of the tower hung a lot of disk-shaped insulator, which is to increase the creepage distance, usually made ​​of glass or ceramic , called insulators. Insulator in the overhead transmission line plays two fundamental roles, namely, support wires and prevent current back to the ground, these two roles must be guaranteed, insulators should not be due to environmental conditions and electrical load changes caused by various electrical and mechanical stress and failure, otherwise the insulator does not have a significant effect, it will damage the whole line use and operational life.

A Pin Insulator

Pin insulator

Pin insulator

A Pin insulator consists of a non-conducting material such as Porcelain, Glass, Plastic, Polymer, or Wood that is formed into a shape that will isolate a wire from a physical support (or “pin”) on a telegraph, utility pole or other structure, provide a means to hold the insulator to the pin, and provide a means to secure the conductor to the insulator. By contrast to a strain insulator, the pin insulator is directly connected to the supporting pole. The earliest pin insulators predate the strain insulator and were deployed before about 1830. Pin insulators continue in production with manufacturers worldwide.

Porcelain Insulators

Porcelain Insulator

Porcelain Insulator

A Insulator made by hard paste of Porcelain is also known as true porcelain insulator. Out of all the wide varieties of ceramics & true porcelain is the hardest, the most durable – which is one of the reasons porcelain insulator are largely replaced glass insulators, beginning in the nineteenth century – porcelain was first created in China, and to this day that country is the source of most superior porcelain products, such as electrical porcelain insulator. In fact, the world’s largest manufacturer of electrical Porcelain insulator is located in Dalian, China.
