TruComponents 656432 Stranded LiY-Z 2x1mm² Red/Blk 20m

CCA describes bi-metallic single and multi-wired lines/cables that are copper-plated with an aluminium core for high-frequency usage areas. Specification explanation: The "skin-effect", also known as current displacement, is a physical phenomenon caused by high-frequency alternating currents. The current density inside the conductor reduces compared to that at the outer surface as the frequency increases.
