Suspension clamps for overhead lines are made from aluminum alloy, cotter-pin is made of stainless steel, other parts are made from hot-dip galvanized steel.
According to suspension clamps design, Suspension clamps for overhead lines can be divided into
◆ Suspension clamps (trunnion type)
◆ Top clamp for post insulator
◆ Suspension clamp for twin jumper conductors
◆ Suspension clamps for 500kV
◆ Suspension clamps (Elen’s type)
◆ Double suspension clamp for vertical arrange
◆ Armour-grip suspension clamp etc.
