The skin effect and proximity effect are two phenomena that increase the effective resistance of a conductor, leading to greater power loss, particularly in AC transmission.

• Skin Effect: This is the tendency of alternating current (AC) to flow primarily near the surface, or "skin," of a conductor, rather than being evenly distributed throughout its cross-section. This reduces the effective cross-sectional area available for current flow, thus increasing the conductor's resistance and resistive losses. The effect becomes more pronounced at higher frequencies.

• Proximity Effect: This occurs when the alternating magnetic fields from nearby conductors in a cable or tower distort the current distribution in each other. This pushes the current to concentrate on the sides of the conductors closest to each other, further increasing the resistance and heat generation.

As a manufacturer of OHTL stringing equipment, we understand the importance of conductor design and spacing to mitigate these effects. Our tools help ensure proper conductor tension and spacing, which are critical factors in reducing the impact of proximity effect.
