At present, there are few backup protection measures for power lines when the wire clamp breaks and the wire falls off. Most of the existing solutions are to strengthen the mechanical properties by adding top-hinged tension clamps. Comparative document CN115954822A-Parts for alleviating stress concentration of tension clamps and tension clamps, by setting the parts for alleviating stress concentration of tension clamps of the present invention, a smooth transition is achieved at the outlet of the steel anchor or the outlet of the wire clamp to reduce the stress concentration coefficient, thereby alleviating the stress concentration at the place, so as to effectively avoid the breakage of the steel core, aluminum strands, etc. under the same load, avoid accidents, and effectively reduce the frequency of tension clamp breakage accidents during line operation. The comparative document and the existing mechanical reinforcement only increase the strength of the crimping tube, and the wire will be disconnected after the crimping tube breaks.
