Performance Of Pre-twisted Wire Under Icing Conditions

As ice thickness gradually increases, the steel wires within the spiral structure can distribute localized loads through mutual support and their own deformation, reducing material fatigue accumulation caused by a single stress point. This is one reason why armor rod preformed is widely used in the design of tension clamps and other accessories. Furthermore, preformed armour rod is often used in conjunction with galvanized or aluminum-clad steel materials, whose surface treatments help maintain the stability of metallic properties in low-temperature and humid environments.

When ice accumulation on the upper part of the line causes additional bending and tensile loads, the stranded structure of armor rods can buffer stress transmission within a certain range. This reduces stress concentration caused by ice adhesion, which helps extend the service life of the overall fittings.
