Abstract
The invention discloses a weathering resistant steel power transmission iron tower which comprises an iron tower body, the iron tower body comprises a plurality of pieces of weathering resistant steel which are fixedly connected, a plurality of wire fixing boxes are evenly installed on the iron tower body, and a power transmission line is detachably installed in each wire fixing box. The bottom end and the two ends of each wire fixing box are jointly provided with connecting holes matched with a power transmission line, two semi-annular clamping plates matched with the power transmission line are symmetrically and movably installed in each wire fixing box, and a two-way threaded rod is rotationally installed in each wire fixing box. The power transmission line is connected into the wire fixing box from the bottom end of the connecting hole, a rotary disc can be fixed after the power transmission line is fixed, the power transmission line can be conveniently fixed, the fixing stability is high, and therefore the situation that the power transmission line falls off from the weathering-resistant steel power transmission iron tower to cause safety accidents can be avoided, and the safety performance of the weathering steel power transmission tower is improved.
Description
