Wherein：1- conductors；2- inner insulating layers；3- external insulation layers.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to external insulation layer 3 that Fig. 1-2, a kind of Aero-Space single condctor, including ecto-entad be arranged in order, interior
Insulating barrier 2 and conductor 1；The external insulation layer 3, the cross section of inner insulating layer 2 are annular shape；The conductor 1 is using soft special thin
Silver-gilt copper wire or nickel plating copper wire are made through multicore bundle strand Wiring technology, and bundle strand pitch multiples are not more than 20 times, it is ensured that conductor 1 is close
Without wire jumper；The inner insulating layer 2 is made of polytetrafluoroethylmaterial material；The external insulation layer 3 is made of polyimide material；
Using double-layer thin wall insulating barrier, the external insulation layer 3, inner insulating layer 2 extrude technology, high temperature sintering technique system using high temperature
Into, one inner insulating layer 2 is extruded using high temperature extrusion equipment on the surface of conductor 1, interior insulation 2 uses high temperature sintering technique after extruding,
One external insulation layer 3 is extruded using high temperature extrusion equipment in the outside of inner insulating layer 2, external insulation layer 3 uses sintering technology after being molded,
Two insulating barriers use high temperature extrusion equipment, are extruded in the outside of the conductor 1 at center, solidify through high temperature sintering, form Aero-Space
It is its flexible, close structure, in light weight with single condctor, and with excellent mechanical performance, high flame resistance, high cracking resistance
Performance, superpower high and low temperature resistance, the high-lubricity of remarkable radiation resistance and double-decker；The inner insulating layer 2
Thickness be 0.06mm, the thickness of the external insulation layer 3 is 0.12mm.
Leader cable of the present utility model has the following advantages that：
The Aero-Space single condctor has excellent mechanical performance, using inside and outside double-layer thin wall insulating barrier, alleviates
Slow-witted the deficiencies of, should easily shrinking, ftractureing defect that traditional single insulating layer is brought, can preferably be balanced using double-layer thin wall insulation
The stress of product, reduces mechanical friction and makes power in wire work, so as to effectively prevent that electrical property declines caused by abrasion
And compensate for polyimides not hydrolysis the defects of, it is still unaffected in the case of hot and humid；Fire resistance is good, gathers
Acid imide is self-extinguishment flame retardancy polymer, and pole is not easy to light, and smoke rate is low, and its density is light, small volume, can preferably coordinate height
