Aforesaid aircraft engine observing and controlling cable, is characterized in that: the count of described pure nickel wire woven separated-shielding layer and pure nickel wire braided overall-shielding layer is all greater than 80%.
The invention has the beneficial effects as follows: by adopting ultrathin synthetic mica, fine pure nickel monofilament, high temperature oxidation resisting silica fibre silk and high-temperature resistant coating; Identical tension loosening, finely strandedly sew ad hoc structure and the technique such as line, FEP sheath, make cable of the present invention have following advantage:
1, long-term operating temperature ratings scope is :-60 ~ 500 DEG C;
2, the short-term flame characteristics of resistance to ultrahigh-temperature: resistance to 1100 ± 100 DEG C of flames are jetted 30 minutes;
3, meet high-temperature region and low-temperature space to the various different particular/special requirement of cable simultaneously, drastically increase the reliability of institute's connection line;
4, excellent electric durability energy;
5, excellent core-screen capacitance characteristic;
6, the earth resistance of cable shielding is adjustable;
7, during long term storage without the need to carrying out special protection against the tide, anti-wet process.

In figure: 1, pure nickel conductor, 2, synthetic mica, 3, silicon oxide fibre braid, 4, high-temperaure coating, 5, pure nickel wire woven separated-shielding layer, 6, pure nickel wire braided overall-shielding layer, 7, FEP sheath, 8, pure nickel monofilament is stranded sews line.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
A kind of aircraft engine observing and controlling cable, comprise multiply pure nickel conductor 1, described multiply pure nickel conductor 1 is all wrapped in same pure nickel wire braided overall-shielding layer 6, described pure nickel wire braided overall-shielding layer 6 is outer is also enclosed with FEP sheath 7, described each pure nickel conductor 1 is outer is enclosed with synthetic mica 2 and silicon oxide fibre braid 3 all successively, described silicon oxide fibre braid 3 is wrapped with high-temperaure coating 4, and described high-temperaure coating 4 is outer also includes pure nickel wire woven separated-shielding layer 5.
Described pure nickel conductor 1 adopts Minimal Tension twisting process, and making it becomes the multiple twisted wire core of multiply pure nickel, ensures that stranded conductor has corresponding pliability and rounding property; Described synthetic mica 2 is the wrapped ultrathin synthetic mica of identical tension, and thickness is 0.08mm ~ 0.10mm, and synthetic mica 2 is wrapped in outside pure nickel conductor 1, described silicon oxide fibre braid 3 adopt Tex be 30 ~ 60 high temperature oxidation resisting silica fibre silk, low-tension braiding form; Ultrathin synthetic mica 2, silicon oxide fibre braid 3 and high-temperaure coating 4 ensure that the Stability Analysis of Structures of this cable, meet simultaneously the setting of external diameter, electric strength and transmission electric capacity respective requirement, solve the contradiction that between three, mutual restriction not easily balances, cable is made to have the characteristic (1100 ± 100 DEG C of flames are jetted 30 minutes, and cable still can normally work) of the short-term flame of resistance to ultrahigh-temperature; Pure nickel wire braided overall-shielding layer 6 simultaneously, employing diameter is that the pure nickel wire high-tension braiding of 0.08mm ~ 0.12mm forms, and count is greater than 80%.Ensure that cable general structure stablizes rounding, and the earth resistance shielded during cable high/low temperature meets the requirement of setting, dramatically reduces the weight of whole cable simultaneously; The application of FEP sheath 7, achieving high-temperature region cable is connected (when reality uses with the connectorless of low-temperature space cable, the FEP sheath of high-temperature region cable part is removed), both make former height warm area device work into unit cable by two cables by the connection of coupling and directly connect height warm area device work, improve the fail safe of this observing and controlling cable connection line and reliability in addition low-temperature space cable also there is excellent protection against the tide, moisture-proof characteristic, also reduce the weight of whole cable assembly simultaneously.Thus without the need to the protection against the tide of special protection, a damp proof difficult problem when also solving this high reliability cable long term storage.
Described high-temperaure coating 4 is outer also includes pure nickel wire woven separated-shielding layer 5, described pure nickel wire woven separated-shielding layer 5 adopt diameter be 0.08mm ~ 0.12mm pure nickel wire high-tension braiding form, count is greater than 80%, when ensure that cable high/low temperature, cable structure is stablized, every characteristic all meets the requirement of setting, also plays the effect alleviating cable weight simultaneously.
The gap location formed between the gap location that described pure nickel wire braided overall-shielding layer 6 and each pure nickel wire woven separated-shielding layer 5 are formed and each pure nickel wire woven separated-shielding layer 5 is equipped with that pure nickel monofilament is stranded sews line 8, described pure nickel monofilament is stranded sews the pure nickel wire low stress twisted synthesizing cable that line 8 is 0.08mm ~ 0.12mm, ensure that the stable rounding of the construction of cable, also achieve cable ground connection adjustability and accordance.
In sum, a kind of aircraft engine observing and controlling cable provided by the invention, solved the contradiction of restriction mutually between the high temperature resistant requirement of cable, outer diameter of cable setting, operating voltage requirement and transporting requirement by material selection, cable structure and suitable technological design, a kind of aircraft engine observing and controlling high reliability observing and controlling cable is provided.
