Abstract

The invention discloses a marine-resistant light cable structure for a ship-borne engine, and solves the problem that the existing cable structure is difficult to meet the requirements of corrosion resistance indexes such as acid atmosphere resistance, acid salt fog resistance and mould resistance. The cable structure comprises a wire, a polytetrafluoroethylene film, a wave-proof sleeve, a heat-shrinkable sleeve, a mold shrinkable sleeve and a tail accessory. The structure has the characteristics of high temperature resistance, vibration resistance, marine environment resistance, electromagnetic shielding, light weight and the like, and is suitable for line connection among an annunciator, a sensor and a controller on an aero-engine, so that the cable can work for a long time in marine andcomplex electromagnetic environments, the weight is reduced, and the advantages of lower oil consumption and higher power are brought to an airplane.

Description

technical field [0001] The invention belongs to the technical field of ocean-resistant cable protection, and in particular provides an ocean-resistant light cable structure for a shipboard engine. Background technique [0002] Naval products, especially those supporting carrier-based aircraft, are more corrosive in the ocean environment. The electrical connectors used in ordinary engine cable products are general-purpose products, which are difficult to meet the requirements of corrosion resistance performance indicators such as acid atmosphere, acid salt spray and mold. When salt mist entraining sea salt particles settles on exposed metal surfaces, due to sea salt (especially NaCl and MgCl 2 ) is easy to absorb water and deliquescence, and it is easy to form micro-batteries and macro-batteries on the metal surface to increase the corrosion activity, destroy the passivation film on the metal surface, and promote the formation of pitting corrosion and crevice corrosion. Once...
