FIELD: electrical engineering.
SUBSTANCE: invention relates to the development of complex insulating shielding casings. Complex two-layer insulating screening sheath (braid) for electromagnetic and electrostatic screening of wires was developed, cables and harnesses, used in the installation of airborne cable networks of aircraft in aeronautical and space technology. Insulating shielding sheath is made of two-layer, where the inner layer is made of a thermo-resistant polyimide yarn entwined with a metallic thread, and the outer layer is made of a thermo-fireproof polyimide yarn.
EFFECT: shell has a low specific gravity, manufacturability in the manufacture and installation, high mechanical characteristics, resistant to radiation and other radiation, liquid fuel, oil products, oils, acids, organic solvents, microbiological effects.
