This is true that the insulators utilised in overhead transmission lines are colored in brown but they are colored only in brown , this is not accurate . There are several other colors also offered like green and blue . The choice of colour of the insulators is purely based on the choice of the owner of energy program .
Generally within Vintage glass insulators Collectors Weekly , a smaller CD quantity represents a smaller sized insulator. glass electrical insulators annum detailed breakdown of these CD designs can be found in this section. Note that lightning rod and radio strain insulators are not incorporated in this CD numbering program.
In 1850 businesses such as Hemingray, Bookfield and Whitall Tatum began making glass insulators for telegraph lines, phone and energy transmission lines later on. This contrasts with other supplies, semiconductors and conductors, which conduct electric current a lot more simply.
For new construction they will only at times use glass on the high power pylons. In other nations, it is different, they truly use glass, but we use porcelain in America. I consider it’s less expensive to manufacturer and mechanically they are a small stronger. The transition to porcelain began in the 1950s and by 1970 they were pretty a lot carried out.
They’d go out and do a job and there’d be an old pole with antique insulators on them. They’d swap out the old ones with the new ones and to everyone else, the old have been just junk.

Ian Macky Explains the Colors and History of Insulators
Why are insulators Brown in Colour?
Why do insulators come in so many colors? In general, insulators were not made in specific colors for any reason. The natural materials that were used to make glass, including sand and glass cullet, tended to make light aqua to aqua colored insulators. Some batches were more green, others more blue.
- Typically the guys who uncover the old ones do a lot of research on where poles used to be and they’ll spend many years digging about.
- When corona discharge occurs, the air in a region about a higher-voltage conductor can break down and ionise without having a catastrophic enhance in present.
- The conductor is suspended at the bottom finish of this string even though the leading end is secured to the cross-arm of the tower.
- Glass insulators for wiring began to be manufactured in the mid 1800s in response to the technology of the time.
