For connecting lightweight electrical devices (radio devices, table lamps, clocks, etc.) under 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-core cables with a copper-clad aluminum core for higher frequency applications. Specification explanation: The so-called skin effect, also known as 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: CCA conductor, flexible, flat design.
