Abstract
In a unit for mounting a primary insulator for power lines onto a pin, a threaded element has an inner diameter which decreases along the length of the threaded element from its top to bottom. The threaded element surrounds a portion of the pin, forming a gap defined by the outer peripheral surface of the pin and the inner diameter of the threaded element. An adhesive resinous material, such as epoxy, is permitted to cure within the gap and forms a strong bond with the pin, which may be metal or fiberglass. An interference fit, or interlock, is formed between the threaded element and the adhesive resinous material. The threaded element may be plastic, and a lubricating powder may be dispersed throughout the threaded element.
