In order to support this lateral load, strain insulators are used.

Strain insulators were first used in telegraph systems in the mid 19th century.

The invention of the strain insulator was a critical factor in allowing higher voltages to be used.

Strain insulators are typically used outdoors in overhead wiring.

The strain insulators are attached to the crossarms.

The earliest pin insulators predate the strain insulator and were deployed before about 1830.

In addition to transferring the roof load to the columns these girders also have the 'V' strain insulators attached to them.

A dead-end tower uses horizontal strain insulators and where the conductors mechanically terminate.

By contrast to a strain insulator, the pin insulator is directly connected to the supporting pole.

In practice, for radio antennas, guy-wires, overhead power lines and most other loads, the strain insulator is usually in physical tension.

For low voltage lines (less than 11 kV), shackle insulators are used as strain insulators.

Dead-end structures support the full weight of the conductor and also all the tension in it, and also use strain insulators.

Ideally, it is a straight wire strung as high as possible between trees or buildings, the ends insulated from supports with strain insulators.

Shackle insulator - In early days, the shackle insulators were used as strain insulators.

To prevent this, each guy wire is divided by strain insulators into multiple sections, each segment non-resonant at the transmitted wavelength.

Strain insulator - A dead end or anchor pole or tower is used where a straight section of line ends, or angles off in another direction.

The strain insulator is used to relieve the line of excessive tension, which happens when there is dead end of the line or sharp curve.

Strain structures resist net tension in the conductors and the conductors attach to the structure through strain insulators.

Strain insulators must be strong enough mechanically to support the full weight of the span of conductor, as well as loads due to ice accumulation, and wind.

Sequences of two or more strainer pylons are uncommon in a powerline because strainers require twice as many strain insulators as ordinary pylons.

Electric power transmission uses hree types of overhead insulator: pin insulator, suspension insulator, and strain insulator.

An in-line dead-end tower will have two sets of strain insulators supporting the lines in either direction, with the lines connected by a jumper between the two segments.

The strain insulator is the same as a suspension insulator but it is used horizontally, whereas the suspension insulator is used vertically.

A strain insulator is an electrical insulator that is designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable.
