As preferably, described the first anchor ear comprises symmetrically arranged two M shape clips and matching used two first connection risers and two the first studs, a described M shape clip is comprised of two horizontal free ends and arc coupling part, the horizontal free end of a described M shape clip and the corresponding first end that connects riser thereof are bolted to connection with corresponding cross-arm vertical panel respectively, described the first studs passes a cross-arm vertical panel of homonymy successively, one first connects riser end, the horizontal free end of one the one M shape clip, another horizontal free end of a same M shape clip, after another the first connection riser end and another cross-arm vertical panel, its two is tightened fixing by nut.This anchor ear is owing to connecting the restriction of the nut at riser and studs and two ends thereof for M shape clip position, M shape clip is not yielding under load-bearing state yet, support relatively good, even after the distortion of M shape clip, the framework being surrounded by connection riser and studs also can form support on electric pole.
As preferably, described the second anchor ear is comprised of symmetrically arranged two the 2nd M shape clips, matching used two second connection risers and two the second studs, and the bottom, one second that described the second studs passes an inclined support bar of homonymy successively connects one end of riser, another horizontal free end of the horizontal free end of one the 2nd M shape clip, same the 2nd M shape clip, another second connection one end of riser and Hou Qi two, bottom of another inclined support bar are tightened fixing by nut.Simple in structure, easy for installation.
As preferably, the manufacture method of described cross-arm is as follows: the glass fibre of dipping vinyl ester resin, under the effect of haulage gear pulling force, by mould shape, and is fixed in mould, from taking out and be cut into and require after length through cutting machine mould, at the anti-aging coating of product surface brushing.
Compared with prior art, the cross-arm that the invention has the advantages that, adopts fiberglass to make, the light intensity of quality is high, corrosion-resistant, good insulation preformance, and useful life is longer, and the glass fiber reinforced plastic insulator of being made by winding process is non-friable; Two, below the first anchor ear, add the second anchor ear being connected with cross-arm two ends by inclined support bar, increased support strength, thereby reduce potential safety hazard, and after the first anchor ear corrosion damages, also have together and support and ensure, certain repairing time can be provided.
