A strain insulator is an electrical insulator that is designed to work in mechanical tension, to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring
Strain insulators on high-voltage power lines
Low-voltage "egg"-type strain insulator, used in utility-pole guy cables to prevent any voltage on the guy caused by an electrical fault on the pole from reaching the lower sections accessible to the public
High-voltage strain insulators used on 66 kV, 230 kV and 115 kV AC lines. The number of insulator skirts varies with voltage and atmospheric conditions.
Pyrex-glass strain insulator used for radio antennas
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors suspended by tower
Strain insulator
…strain), to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring, to support radio antennas and overhead power lines. A strain insulator may be inserted between two lengths of wire to isolate them electrically from each other while maintaining a mechanical connection…
