What Happens If The Suspension Clamp Doesn't Have Enough Grip?

When the gripping force of suspension clamp for lt ab cable is insufficient, relative slippage will occur between the wire and suspension clamp. Insufficient clamping force reduces the gripping effect, causing the conductor to slightly shift or slide significantly along the surface of fiber suspension clamp under load. This phenomenon, known as clamp slippage in bridge cable structures, has been confirmed by relevant mechanical analyses to alter the cable force distribution.

After conductor slippage, the original force balance is disrupted. For transmission lines, this can lead to sag control imbalance, affecting the conductor tension distribution and consequently altering the stress state of the towers or insulators. Prolonged exposure to this unstable state can cause localized stress concentration, increasing the risk of component fatigue.
