Abstract
An insulator having a torque-resistant or torque-prevailing crimped insulator end fitting; including a method of crimping the insulator end fitting so as to be resistant to torque tending to loosen mounting bolt connections of the insulator. A fiberglass core is located in the insulator and protrudes from the opposite ends of the insulator, and has end fittings seated thereon in close interference engagement, by mounting the insulator through intermediary of the end fittings being attached to power devices by threaded bolts extending from the devices being engaged in the tapped bolt holes. Radially inwardly directed crimping forces are applied to the cylindrical wall structure of the end fittings intermediate the locations of the bosses having the bolts tightened within the threaded bolt holes, and thereby produce a bolt-locking deformation of the bolt holes.
