Description
Technical field
The utility model relates to a kind of Aero-Space polytetrafluoroethylene and inorfil combination cable.
Background technology
At present; the tunnel dielectric layer of Aero-Space mainly adopts and extrudes FEP polytetrafluoroethylene; therefore the security performance such as vibration resistance, shock resistance, tensile strength of wire will be improved; additionally layer protective layer need be added outward at the former process structure of wire; add volume and the weight of wire, do not meet the requirement of space flight and aviation product to miniaturization, lightness, high reliability future development.
Utility model content
The purpose of this utility model is exactly to solve the problem, provide that the volume required for aviation in a kind of day is little, lightweight, vibration resistance, shock resistance, tensile strength is high, security reliability is high Aero-Space polytetrafluoroethylene and inorfil combination cable.
To achieve these goals, the utility model adopts following technical scheme: a kind of Aero-Space polytetrafluoroethylene and inorfil combination cable, comprise body, described body has multiply multicore stranded conductor, by multiply, silver-plated or nickel-clad copper skein silk closes and forms per share multicore stranded conductor, PTFE and inorfil combined insulation layer are set outside described multicore stranded conductor, outside described insulating barrier, sheath is set, described sheath is nickel plating or silver-gilt copper wire screen, or PTFE green tape sheath, or the nickel plating of inside and outside setting or silver-gilt copper wire screen and PTFE green tape sheath.
Further, described multicore stranded conductor is three strands.
Further, the thickness of described insulating barrier is 0.15 ~ 0.16mm.
Further, the outer surface of described sheath arranges along cable axis direction and prevents turning round recess or preventing turning round colour band.
Further, the described anti-cross section turning round recess is arcuation.
Compared with prior art, the utility model has following beneficial effect:
(1) external diameter is little, lightweight: conductor adopts that multiply monofilament is stranded in the same way to be formed, compact conformation, stable, the conductor diameter of same cross-sectional is reduced many; Insulating barrier adopts PTFE(polytetrafluoroethylene)/inorfil combined insulation, make the reduction of this product outer insulation diameter, weight saving.
(2) humidity and chemical solvent dipping: polytetrafluoroethylmaterial material itself has excellent humidity and chemical solvent dipping, adopts inorfil combined insulation more to improve humidity and the chemical solvent saturating machine of wire.
(3) high-and low-temperature resistance: 250 DEG C, silver-plated copper core, 260 DEG C, nickel-clad copper core, still keeps under being not less than the condition of-65 DEG C or around property in ambient temperature.
(4) safe and reliable: because insulating barrier have employed polytetrafluoroethylene/inorfil combined insulation, improve the vibration resistance of this kind of electric wire, shock resistance, tensile strength, withstands corona performance, anti-insulation cracking performance.
