| Description : | An electrical insulator made of clear glass with a green tint. The top is dome shaped with two protruding groves encircling the diameter. The underneath the bottom of the insulator, there is a series of small ball-like decoration around the diameter. The inside of the insulator is hollow with spiral grooves for screwing. On the outside of the insulator there are two inscriptions which can be found near the bottom. The first reads "DOMINION - 42" and the second is the letter "D" inside of a diamond shape. |
| Commentaires : | Insulators made in Canada were manufactured by the Diamond or Dominion Glass Company. The Dominion Glass Co. was established circa 1886 by the Barsalou family of Montreal. However, the company itself only became incorporated on October 22, 1894. Although the Dominion Glass Co. is most well known for their production of mason and fruit jars, during the late 1920's they also began to make glass insulators used to protect utility poles from the electrical current within the wires. All insulators were made in their Wallaceburg, Ontario plant except for during a short period of time when an influx of demand for their supplies required the Dominion Glass Co. to manufacture glass insulators in their Redcliff, Alberta plant. The insulator model entitled No.42 was first manufactured in February of 1927 and continued it's production well into the 1960s. However, those with drip points along the mouth at the bottom are those that were manufactured prior to the late 1940s. The use of insulators on utility poles was discontinued during the late 1970s when improved technology made them obsolete. However, since their discontinuation, they have become a popular collectors item with coloured glass insulators being the most highly valued. |
| Fonctions : | Glass insulators where first introduced in the mid to late 1800's as a means to protect wooden electrical poles from the electrical current that was carried through the electrical cables. They could be found at the very top of electrical poles were the cables met the pole. |
