This text is machine translated.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 in the inside of the conductor becomes lower with increasing frequency than that at the outer surface. The inner cross-section area of a conductor through which high-frequency alternating current is flowing practically does not do any transmission function. The network cable - CCA is thus a really economical and weight-reduced alternative to the conventional full-copper line and this at equivalent power and transmission characteristcs.
