FITTING, INSULATOR AND COMPOSITE CROSS ARM COMPRISING SAME, AND TRANSMISSION TOWER

WIPO Patent Application WO/2017/167133

A1

A fitting (101, 201, 301, 403, 404), an insulator (102, 202, 302, 402) and a composite cross arm (140, 240, 340, 440) comprising same, and a transmission tower (150, 250, 350, 450). The fitting is connected to an end of the insulator and comprises a head portion (110, 210, 310), a fixed portion (120, 220, 320), and a rotating portion (130, 230, and 330). The fixed portion is fixedly connected to the end of the insulator. The head portion is configured to be connected to an external device, is rotatably connected to the fixed portion by means of the rotating portion, and is capable of rotating around the axis of the insulator by 360º. The fitting has no limitations in direction, and during mounting of the insulator, the head portion of the fitting can be rotated arbitrarily according to angle requirements of a connection part of an external device, so that following matching can be implemented during connection to ensure successful mounting; moreover, stress concentration on the fitting can be effectively avoided, such that fatigue and stress damage degrees of the fitting can be reduced and the service life is effectively prolonged.
