Cables are typically formed by twisting several wires or groups of wires (each group containing at least two wires). The wire groups are insulated from each other and commonly twisted around a central core, with the entire assembly covered by a highly insulated sheath that provides flame-retardant and electrostatic shielding properties. This product is primarily used for connections in power installations, lighting, electrical appliances, instruments, telecommunications equipment, and other apparatus with a nominal alternating current voltage not exceeding 450/750V.
