Suspension clamps
Suspension Clamps
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 aluminium alloy.
The suspending angle of suspension clamps is not less than 25° , the radius of curvature is not less than 8 times of the conductors diameter, and the percentage of the grip strength for different conductor will not less than the rated broken strength as show in the table
The meaning of the letter& arabic figure in the catalogue are shown as follow.
X(C)-suspension clamp G-fixed S-double clamp U-u bolt J-strengthened H-aluminium alloy F-anti-corona type K-overhead type T-envelope type A-Bowl head hanging board
B-With U-shaped hanging plate X-dropping type
The slip strength of suspension clamp to rated tensile strength of conductors is shown in the table.
As the suspension clamps are used to AAC and ACS and ACSR , the conductor may be wrapped by aluminium tapes or preformed armor rods to protect conductor ,these taps or rods are calculated in the diameter of conductor.
