ABSTRACT:
A suspension clamp (10) has a stirrup part (12) with an upper end adapted for pivotal connection to a string of insulators (S) of a transmission tower. A clamping part (14) is accommodated within the stirrup part (12) for clamping onto the overhead conductor (L) supported by the towers. A releasable connection (34) is provided between the stirrup part (12) and the clamping part (14) for releasing the clamping part (14) from the stirrup part (12) whenever a predetermined excessive longitudinal force is exerted by the overhead conductor (L). The stirrup part (12) holds the line together with the clamping part (14) suspended once the clamping part (14) has been released from the stirrup part (12).
