About

Guy strain type porcelains are used in low and medium voltage lines. They are designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable. Guy strains 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, or where a wire attaches to a pole or tower, to transmit the pull of the wire to the support while insulating it.

GAMMA guy strain type insulators are designed, manufactured and tested according to ANSI standard (C29.4) using wet shaping processes. These insulators work under compression efforts instead of tension.

Insulator's surface is covered with a waterproof glaze coat, which allows the porcelain to stay free from dust and dirt caused by environmental contamination. Gray, white or brown glazing is available according to customer requirements.
