For connecting lightweight electrical devices (such as radios, table lamps, clocks, etc.) with very low mechanical stress in households, as permitted by the relevant device regulations. The cable can also be used as a speaker cable. Notably, the conductor diameter of 6 mm² is suitable for connecting HiFi speakers. The cable is not suitable for connecting cooking and heating devices or for outdoor use. CCA refers to bi-metallic single and multi-stranded wires/cables with a copper-clad aluminum core for high-frequency applications. The so-called skin effect, or current displacement, is a physical phenomenon caused by higher frequency alternating currents. The current density inside the conductor decreases with increasing frequency compared to that at the outer surface. Special feature: flat design, flexible.
