Abstract
Ceramic elements which can be clamped together by means of a tension rod so as to form a cross-arm assembly for a utility pole. The elements are provided with recesses which receive electrical conductors, with clips being provided so as to retain the conductors within the recesses. The elements thus provide physical support for the conductors and also form the insulating medium for the conductors.
Claims9
A utility pole assembly, said assembly comprising:
- a utility pole, a cross-arm, a bracket connecting the cross-arm to the pole and a pair of stays which extend from the pole to spaced locations on the cross-arm, said cross-arm comprising a plurality of ceramic elements each including a bore therethrough, said elements being arranged so that their bores are aligned, said cross-arm including spacing means located between adjacent elements, each spacing means having openings therethrough, said cross-arm further including a tension member which passes through said bores and said openings and clamps said elements together, and wherein each element comprises a body having a top portion with conductor support means for supporting an electrical conductor which in use extends transversely relative to the cross-arm, said bracket having an opening therein which is generally complementary in shape to the body so that the cross-arm can extend therethrough and be firmly clamped by the bracket to the pole.
