T-type cross-arm for preventing nest of magpie in electric pole

摘要

The present design relates to preventing home gyeongwan gold T-wangeum band to the pole.; The subject innovation is, install to correspond to both sides of the normal of the pole 100, the one side wangeum band 10 'by having a' T-shaped wangeum band 10 (10 with) the fitting hole 12, 12 'on each side inner attaching the arc-shaped contact plate 11 on the said wangeum band 10 (10 ') outside the center of the outer surface of the space enclosed rectangular holder 20 (20' form a) integrally, and the length is long fixing bolt 30 (30 ') the wangeum band 10 (10') both the coupling hole 12, 12 'on each of the nut 40 to the coupling, for fixing the other hand, the fixing bolt (30 penetrate the ) (30 ') at both ends it has a conventional gyeongwan gold 200, the distance holder (20, 20') of the contact face into the nut (40 'to be) fixed to the structure.; The subject innovation is the distance holder is provided by the wangeum band of the pair are configured integrally to easily expand the width of each side gyeongwan cracked essentially to prevent that the blackcurrant to build houses for formatting gyeongwan gold.; In other words, the present design is that the structure is simple and easy to install a magpie caused more than an expensive distribution equipment due to the Shrike habitat by providing habitat protection and to prevent various track accidents This disruption caused power supply in advance, on the other hand, also it has benefits such as to reduce the economic loss of human and material according to to recover it.
