XGU series trunnion type malleable iron suspension clamp/ electric pole clamp is mainly used for overhead electric line, suspending conductor on the insulator or lightning conductor on the lamp tower through connecting fittings. It is made up of aluminum alloy, with minium loss of magnetic hysteresis & eddy current as well as light weight & convenient installation. It has accessed to the criteria of energy-saving & consumption reduction for Chinese state grid reconstruction. When it used for aluminum-stranded wire & ACSR, the priority shall be wrapped aluminum armor tape or armor rods on the conductor for protecting the conductor.
The suspension clamp is used to fix conductors to insulator strings or hang lightning conductors on straightline towers. Moreover, it also can be used for transposition towers to support transposition conductors and for tension towers or angle poles to fix the jumper wires.
As the suspension clamps are used to ACSR, the conductor may be wounded by aluminium tapes or preformed armour rods for protecting protecting these taps or rods are included in the diameter of suitable conductor.
The meanings of letters and numbers in the model in the table are:
X – suspension clamp; G – fixed;  U-U bolt; Number – applicable wire combination number;Additional word  A – Hanging board with magnetic head;B – with U  Clevis
Ground double hanging point pre twisted suspension clamp
The Clamp body and keepers are made of aluminium alloy
The Cotter-pins are made of stainless steel,
The other parts are  hot-dip galvanized.
(1) The overhanging Angle of the suspension clamp is not less than 25°.
(2) The radius of curvature of the overhanging wire clip shall not be less than 8 times of the diameter of the installed wire.
(3) The gripping force of the suspension wire clip on different wires and the percentage of rated tensile resistance of wires
