Glass fibre-reinforced plastics tension rod for insulator - anchored in end fitting of insulator for transmission of tensile forces to all glass fibres
Glass fibre-reinforced plastics tension rod for insulator - anchored in end fitting of insulator for transmission of tensile forces to all glass fibres
Insulator tension rod is made of glass-fibre-reinforced plastics, pref. a thermosetting plastic material, and its end is anchored in an end fitting of the insulator by heating the end until the plastics bond between fibres is weakened; the end is then conically expanded in all directions and anchored in the fitting by filling the gaps with a curable synthetic resin. The drawing shows a view of the expanded tension rod with conical pin, with two variants of the end fitting, on the left conically adapted to the rod, and on the right cylindrical with cementing grooves.
