FIELD: electricity.SUBSTANCE: apparatus consists of two parts, the fixed part of which has a housing with guides for mounting to the fixed part of the structure, and a movable part which is formed by longitudinally movable elements, to the fixed part of the structure. The longitudinally movable part is pair-connected arm supports for free longitudinal movement on guides of the housing which are provided with mounting attachments for the bundled cable. The looped bundled cable is laid while bending in one plane. The pair-connected arm supports for free longitudinal movement are placed equidistant from each other since they are separated by spring elements. The pair-connected arm supports, which freely slide on the guide tubes of the apparatus, have at least two mounting attachments for bundled cables each, for example, for an outer and an inner bundle, wherein mounting attachments on each ear of the arm supports can freely rotate about axes that are perpendicular to parallel bending planes of the bundles that are spaced apart on the height; bending zones of the bundled cables are limited by a minimum allowable bending radius and do not have moments of overlapping (touching) each other.EFFECT: high reliability, longer service life and fire safety.10 cl, 2 dwg |
