Description

The phenomenon of lightning can potentially cause damage to power transmission lines. The damages inflicted upon these lines can be undesirable and costly, as replacing the conductors imposes a substantial financial burden on responsible companies. To prevent such damages, one can employ a steel static shield wire an overhead electrical wire designed to protect power transmission lines from lightning strikes. Static shield wires conduct the current through aerial ground wires and channel it to the ground, preventing harm to the transmission lines. Ground wires placed above transmission lines can contribute to prolonging the system's lifespan. Depending on the design of the transmission lines and prevailing weather conditions, shield wires may have different structures. Enhancing the corrosion resistance of shield wires is achieved by incorporating aluminium-clad steel wires, which offer superior protection against corrosion when compared to galvanized wires. The preference for using aluminium-clad steel wires is particularly pronounced in coastal and humid regions, as well as in urban and industrial areas with higher pollution levels.

To prevent damage from intense transient currents such as lightning strikes and short circuits, the use of steel static shields that function as aerial electrical wires is highly effective. These shields, which are connected to the shield wires, conduct unwanted electrical currents and safely ground them, thereby preventing damage to power transmission lines. Installing these grounding wires above transmission lines not only helps protect the network but also extends the lifespan of the power transmission system. Depending on the design of the transmission lines and environmental conditions, shield wires can have diverse structures. One advanced type of these wires is aluminum-cladded shield wires (AW). Due to their aluminum coating, these wires possess significantly higher corrosion resistance compared to galvanized wires. This characteristic makes AW shield wires an ideal choice for use in coastal and humid areas, as well as in polluted urban and industrial environments. In these regions, where corrosion is exacerbated by environmental conditions, using AW shield wires can significantly enhance the lifespan and efficiency of transmission lines while preventing costly failures.
