What is the main purpose of an insulator?
Electrical insulators are used to hold conductors in position, separating them from one another and from surrounding structures. They form a barrier between energized parts of an electric circuit and confine the flow of current to wires or other conducting paths as desired.

Are glass insulators still used?
During the 1960s, 1970s and 1980s many of these lines were dismantled as technology advanced. Today, a few lines using glass insulators are still in service, but are only a tiny percentage compared to the heyday of open wire communication.

What is an example of insulation?
Insulation definition The act of insulating or the state of being insulated. The definition of insulation is material used to trap air and sound. Fiberglass put into the walls of a house and into the attic in order to keep warm air in and cold air out during the winter months is an example of insulation.

What are three good conductors?
Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
How much is a glass insulator worth?
On average, these glass insulators tend to sell for around $20, though there are special instances where insulators can sell for significantly more than that. Generally, the insulators that sell for more are rare, either because of their manufacturer or their color.
How do you date glass insulators?
Variations and Exceptions: There are some variations, but they generally can be deduced from the above patterns. In all cases, counting the dots and adding them to the mold year code produces the date the insulator was actually produced. Some variations include just a 38 or 39 on the front skirt (for 1938 or 1939).
What type of insulator is 33KV?
Stay insulators are also known as strain insulators and are generally used up to 33 kV line.
How many insulators are in a kV?
We generally use two parts pin insulators for 33KV, and three parts pin insulator for 66KV systems.
