Strain clamp uses for transmission line construction and it was used to tension conductors and earth wires. And strain clamp was installed to tension tower or tension pole, the conductors bears tensile strength. So mostly the strength or failing load of strain clamp is higher than suspension clamp.

Bolted type strain clamps:

Material: galvanized ductile iron, aluminum alloy,
Suit to conductor: aluminum, al-alloy, ACSR, AAC, AAAC, steel cable with or without armor rods
Strength: 20kN, 40kN, 70kN, 80kN, 90kN, 120kN, 160kN, 210KN, 300KN
bolts: 2 bolts, 3 bolts, 4 bolts, 5 bolts
