Concentric cable is a cable consisting of two or more concentric conductors, in particular one of the neutral wires coiled around the inner conductor. The allowable bending radius of concentric cables shall be: a single-core cable shall not be less than 20 times the outer diameter of the cable; The multi-core cable shall not be less than 15 times the outer diameter of the cable. The reactance of the concentric conductor is much lower than that of the fourth conductor of the common four-core cable in the zero-sequence working state, which is conducive to the sensitive action of the short-circuit automatic protection device, thus ensuring the safe operation of cable-related equipment. Cable has strong anti – electromagnetic interference and anti – lightning characteristics. Concentric cable has low and uniform positive (inverse) sequence and zero sequence impedance, which is beneficial to improve power supply quality.
