The skin effect is a property of AC transmission where the current tends to flow through the outer surface ("skin") of the conductor rather than being evenly distributed throughout its cross-section. This is due to the varying magnetic fields produced by the alternating current.

This effect significantly increases the effective AC resistance of the conductor, leading to higher I2R (Joule effect) losses and a reduction in transmission efficiency. The skin effect is more pronounced at higher frequencies and with larger conductor diameters.

To combat this, the industry is increasingly adopting advanced conductors, which are engineered with composite cores to allow for more uniform current distribution and higher capacity. Our company provides the specialized tools and equipment required for the safe and precise stringing and maintenance of these modern conductors, helping to improve the overall efficiency and lifespan of the transmission line.
