Abstract:
1. An anti-cascading suspension clamp arrangement comprising a vertical string of suspension insulators depending downwardly from an overhead transmission tower, and an anti-cascading suspension clamp having a first part pivotally connected to a lower end of the vertical string of suspension insulators, a second part adapted to clamp onto an overhead conductor to be suspended from the string of insulators, a releasable connection between said first part and said second part for releasing said second part from said first part whenever a predetermined excessive longitudinal force is exerted by the overhead conductor, thereby preventing damage to the tower and the insulator, and a conductor catching portion provided at a lower end of said first part for preventing the overhead conductor together with the second part of the suspension clamp from falling to the ground after said second part has been released from said first part.
