FIELD: cable line engineering; solving problem of cable line immunity to external electromagnetic noise.
SUBSTANCE: proposed method for noise suppression in cable lines includes electrical interconnection of two cable conductors on one end directly or through resistors , addition of signals from their other ends, and at least partial disposition, principally symmetrical, of figures formed by one pair of conductors including conductors proper and space between them in space between other pair of conductors. Circuits of interconnected conductors are balanced, for instance, with respect to their resistance. Cable has two pairs of conductors, each pair is directly or mediately parallel-connected and figure formed by one pair of conductors that includes conductors proper and space between them is at least partially disposed in space between other pair of conductors, principally symmetrically. Cable manufacturing process includes insulation of conductors and their relative fastening in space; each pair of four conductors is directly or mediately parallel-connected and disposed in space so that figure formed by one pair of conductors incorporating conductors proper and space between them is at least partially disposed in space between other pair of conductors, principally symmetrically.
EFFECT: reduced fraction of electromagnetic noise in signal transferred over cable lines.
