Glass insulators have been initially produced in the 1850’s for use with telegraph lines. The glass insulator was screwed onto a wooden hook, which was attached to buildings or the power pole, and then the reside electric wire was wrapped around it. The critical aspect of using glass insulators is that the wire doesn’t touch anything else.

But nowadays, if I walk about Yreka, there is hardly any glass at all, normally for telecommunications they use cables, which never have to have insulators. Power line glass insulators have passed tests in the international laboratories. You never see a lot of insulators in the air anymore, except at railroads , and they’re mainly Hemingray 42.

The presence of this hybrid coating resulted in two main benefits: firstly the concentration of the icicles and their lengths were both decreased, and the flashover voltage increased in comparison to the insulators with a typical silicone rubber coating.

In 1850 organizations such as Hemingray, Bookfield and Whitall Tatum began making glass insulators for telegraph lines, telephone and energy transmission lines later on. Their sole objective was to insulate the wire from the wood, cause for which supplies such as glass, porcelain or composite polymer materials had been chosen.

Because practically all railroads (that had been constructed in or prior to the 1950s) originally had communication lines strung alongside them (primarily telegraph, but also in some circumstances phone), railroad buffs (rail fans” or trainspotters”) in some cases turn out to be interested in glass insulators due to the fact they had been such a prevalent sight along old railroad rights-of-way.

Glass insulators had been first developed in the 1850’s for use with telegraph lines. Due to the fact virtually all railroads (that had been constructed in or ahead of the 1950s) originally had communication lines strung alongside them (mainly telegraph, but also in some cases telephone), railroad buffs (rail fans” оr trainspotters”) at times come to be interested in glass insulators considering the fact that they were such a common sight along old railroad rights-of-way.

Suspension insulators also known as Strain insulators, are utilized for the rated voltage of 35~500kV AC energy system in widespread and dirty places, overhead transmission and distribution lines and substations with a frequency not exceeding 100Hz for drape and tensile strength.
