Suspension clamps are used to hang conductor or ground wire through insulators or link fitting to tower arms or substation structures. The clamps are made of malleable iron or amuminium alloy.

The suspension clamp angle of suspension clamps is not less than 25°,the radius of curvature is not less than the dia of installed leads by 8-10, and the percentage of the grip on different kinds of leads to the calculating capability of snap show in following table.

As the suspension clamps are used to AAC and ACSR,the conductor may be wound by aluminium tapes or preformed armour rods for protecting these  taps or rods are included  in the diameter of suitable conductor.
