HIGH FREQUENCY SYMMETRIC CABLE FOR AVIATION AND SPACE TECHNOLOGY

摘要

The claimed utility model relates to cable technology, namely, to the design of high-frequency balanced cables with an extended temperature range for aerospace technology. A high-frequency symmetrical cable for aerospace engineering, includes multi-wire conductors, each of which consists of twisted metal wires and is coated with fluoroplastic insulation. In this case, insulated conductive conductors are twisted in pairs together with cordels, and each pair is enclosed in an individual screen. Moreover, individually shielded pairs, in turn, are twisted around the central cornel from fluoroplastic to the core, enclosed in a common screen, made in the form of a braid of metal wire. A fluoroplastic sheath is superimposed on top of the common screen. The diameter of each cordele in a pair of twisted conductive conductors is 0.7-0.9 of the diameter of one insulated conductive core. The individual screen of each pair is made of laminated aluminum foil superimposed in the form of a winding in the direction opposite to the direction of twisting of the isolated cores in pairs. In this case, the twisting of the pairs into the core is performed in the direction opposite to the direction of twisting of the isolated conductive cores into pairs. Increases radial resistance and stability of cable electrical parameters. 10 s.p. f-ly.
