How geometric strand arrangement, tight lay length tolerances, and consistent annealing mitigate skin effect and reduce AC losses in inverter duty cables and modern EV chargers.
Mitigating Skin Effect & Proximity Losses
In modern electrical systems—including variable frequency drives (VFD), solar string inverters, and high-power EV charging stations—alternating current does not distribute uniformly across a solid conductor. Due to self-induced magnetic fields, current concentrates near the outer boundary (skin effect).
By transitioning from heavy solid conductors to precisely bunched fine tinned copper strands:
Total Surface Area Increases: The effective conductive periphery expands significantly, lowering effective AC impedance.
Mechanical Flexibility Improves: Bunched wire easily navigates tight conduit bends and vibration-prone industrial robotic tracks without fatigue fractures.
Uniform Lay Length: Tekla Energy's double-twist high-speed bunchers deliver consistent pitch, eliminating loose strands and outer diameter spikes.Explore Our Bunched Wire Portfolio
