Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] An aircraft engine measurement and control cable, comprising a plurality of strands of pure nickel conductors 1, the plurality of strands of pure nickel conductors 1 are all wrapped in the same pure nickel wire braided overall shielding layer 6, and the outer layer of the pure nickel wire braided overall shielding layer 6 is It is also wrapped with a FEP sheath 7, and each of the pure nickel conductors 1 is wrapped with a synthetic mica 2 and a silicon oxide fiber braided layer 3 in turn, and the silicon oxide fiber braided layer 3 is wrapped with a high temperature resistant coating 4, so The high temperature resistant coating 4 also includes a pure nickel wire braided sub-shielding layer 5.

[0024] The pure nickel conductor 1 adopts a micro-tension stranding process to make it a multi-strand pure nickel multi-strand wire core, ensuring that the stranding cond...

Abstract

The invention discloses a measurement and control cable for an aircraft engine. The measurement and control cable comprises multistrand pure nickel conductors which are packaged in a same pure nickel wire woven main shielding layer. The pure nickel wire woven main shielding layer is wrapped with a FEP sheath. Outside the pure nickel conductors are coated with synthetic mica, a silicon oxide fiber braiding layer, a high-temperature resistant coating, and a pure nickel wire woven branch shielding layer in turn. The measurement and control cable solves a problem that a cable in the prior art can not realize high performance, light weight, high reliability, high-temperature resistance, etc. at the same time. Through selecting materials and designing cable structure, interactive contradictions among cable high-temperature resistant requirement, cable external diameter setting, working voltage requirement, and transmission requirement are solved and the high reliable measurement and control cable used for aircraft engine measurement and control is provided.

Description

technical field [0001] The invention relates to a high-reliability measurement and control cable, in particular to a high-reliability measurement and control cable that can be used for aircraft engines. Background technique [0002] The development of military and civil aircraft has suddenly put forward higher and newer requirements for new engines. Engines with new performance and high requirements must have high-reliability measurement and control cables that can meet harsh operating conditions. High-performance, high-reliability, lightweight, and high-temperature-resistant measurement and control cables are one of the key components of the new aero-engine, which directly determines the successful application of the new aero-engine. [0003] The fundamental difference between this type of measurement and control cable and the existing cables lies in high performance, light weight, high reliability, and high temperature resistance. However, the development of cables that m...
