Polymer Line Post Insulators By M/s Rashtriya Electrical & Engg. Corpo.

We are one step ahead from our competitors in Making, Exporting and Supplying of Polymer Line Post Insulators in Ghaziabad, Uttar Pradesh, India. Reliability is the most important property of an insulator whether it is a polymeric (composite) insulator or ceramic one. The reliability of an insulator depends upon its electrical and Polymer Line Post Insulators mechanical strengths. With the advent of modern manufacturing, mechanical molding and fixture technique, the mechanical strength is quite reliable. However the electrical strength over decades is not fully guaranteed. The modern style polymeric insulators were introduced about 25 years ago with most recent version about 13 years ago. The reason for this was not failure of ceramic insulators, but the other benefits such as 90% weight reduction, better pollution performance and low associated costs of polymeric insulators over ceramic ones. Experience of outdoor insulation started from the introduction of telegraphic lines. The pin and cap type insulators have been used since the last quarter of the 18th century. These insulators are very reliable. Glass and porcelain insulators were the only type available before the introduction of newer polymeric insulators.
