Link fitting is used to connect insulators to the towers and conductors.The forged hardware is mainly made of heat treated steel.This steel is especially suitable for forging and its good performance, especially ductility, is due to the heat treatment process.
This is of particular value if dynamic loads, for instance through ice shedding or oscillations, are likely.In particular cases, where at very low temperatures dynamic stresses could occur, hardware made of special steels is available.
