Common Defects In Crimping Of Tension Clamps

Area A is the crimping part between the bolted type strain clamp aluminum tube and the steel anchor.
It mainly observes whether the aluminum tube is well crimped with the steel anchor groove.
Area B is the non-pressing area of ​​the dead end strain clamp aluminum tube.
It mainly observes whether the relative positions of the aluminum tube and the steel anchor tube in area B correspond to each other, and whether the steel anchor tube has burrs or deformation.
Area C is the crimping part between the bolted dead end clamp aluminum tube and the aluminum strand.
It mainly observes whether the steel core in area C is lantern-shaped or bulging.
The quality defects of the crimping of bolt-type tension clamps are qualitatively divided into two categories:
Process defects and functional defects.
The two categories of different defects are further refined and classified,
and ranked from small to large according to the influence on the tension between the conductor and the clamp.
