Cables are generally composed of several wires or groups of wires (each group containing at least two wires) twisted together, with each group insulated from one another and often twisted around a central core, the whole assembly covered with a highly insulating sheath providing fire resistance and electrostatic shielding. This product is suitable for signal transmission in electronic computer networks and automation control systems, and for connecting high-precision detection devices and instruments requiring high anti-interference performance, under nominal AC voltages of up to 300/500V or DC voltages of up to 1000V.
