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. They are used in overhead electrical wiring, to support radio antennas, overhead power lines and electric fence.
The insulator is made of Polypropylene(PP), Polypropylene Co-polymer (PPCP) and Polycarbonate (PC) plastics to guarantee a long lifespan. Fitted onto a first or last post for tensioning wires in order to keep the fence tight. Plastic insulator for wooden posts, suitable for cord, wire or corner hooks.
