The primary role for insulators for permenant fencing is to securely hold the fence line without power leaking from post to ground. A well designed insulator will hold the line securely so that it will not wear the tape, rope or wire when buffeted around by the elements or will allow the line to freely pass through without the impedance of sharp edges.
