Insulator for electric transmission and distribution lines, with improved resistance to flexural stresses |
摘要 |
<p>A hollow insulator for electric transmission and/or distribution lines, comprising an insulating tube made of composite material which is coupled, at least at an end portion thereof, to a metal flange; the coupling between the metal flange and the insulating tube is provided by a plurality of connection means adapted to transfer to the flange flexural stresses due to flexural moments applied to the tube, said connection means working substantially under shearing stress. <IMAGE></p> |
