The Role Of Pre-stranded Wire In The Power Grid

Tension concentration is a common mechanical phenomenon at critical connection points of overhead conductors. armor rods conductor extends the tension within the cable over a larger area through its ring-shaped wrapping form, thereby dispersing concentrated loads and improving the line stress profile from a mechanical perspective. This mechanical distribution effect is particularly important in the design of tension clamp assemblies because line operation is significantly affected by environmental factors.

The production history of armor rod preformed can be traced back to the mid-20th century, the formative period of power line accessory technology. It initially emerged to address localized stress and physical damage to bare conductors. As power grids expand and technology evolves, the preformed armour rod product line has also developed various models to adapt to different cable specifications and operating conditions.
