Insulated point rod joints mechanical tests on a new type of insulated point rod joint, and a comparison with the mechanical strength of the present standard insulated point rod joint (E-015)

A new type and the present standard type of insulated point rod joint are shown in Fig. 1. It will be seen that all mechanical loads transmitted through the new type of joint are taken through the Solid Permall coupling. This report describes tensile and bending tests to failure carried...
