Abstract
The present utility model relates to a GWIB high temperature resistant cable. The cable is characterized in that two polyimide composite tape PTFE/PI/PTFE inner insulation layers lapped by a wrapping machine are arranged outside a nickel-clad copper alloy wire conductor stranded by an electric wire stranding machine, a high temperature resistant alkali-free glass fiber external insulation layer braided by a braiding machine is arranged outside the inner insulation layers, a wrapping layer lapped by a mica tape is arranged outside the external insulation layer, and a high temperature resistant alkali-free glass fiber braiding cover layer braided by a braiding machine is arranged outside the wrapping layer. In the cable, the wrapping and sintering technology is adopted in insulation; combined insulation is adopted; the electrical performance, the mechanical performance and the environment resistant performance are good, the cable can endure a high temperature of 400 DEG C, and the cable is high temperature resistant, low temperature resistant, mycete proof, salt spray proof, moist heat proof, small in external diameter, light in weight and soft.
Description
Technical field:
The utility model relates to the GWIB high temperature-resistant cable, can be used as to wait around the aircraft engine to connect under the high temperature particular surroundings and use cable, mainly be applicable to it is the signal and the power transfer of Aeronautics and Astronautics field key position electronic devices and components.
Background technology:
The domestic and international market is that the various high temperature electric wire cables of insulation are the most general with fluoroplastics; Especially be the electric wire product of insulation, sheath material with XETFE, be widely used in aerospace field, but owing to receive the restriction of XETFE material itself; With this material is the cable of insulation, sheath; Its long-term work temperature can only reach 200 ℃, can not satisfy the more requirement of high-temperature work environment, and aircraft industry needs a kind of new product to fill up this vacancy.We select for use the PTFE/PI/PTFE composite material as interior insulation, with the external insulation layer of the high temperature resistant alkali-free glass fibre of braiding machine braiding, through special processing technologys such as oversintering and coatings, have developed the GWIB high temperature-resistant cable.
Summary of the invention:
That the utility model proposes is GWIB high temperature-resistant cable and preparation technology thereof, is that the specific (special) requirements to cable designs according to the characteristics of aircraft engine environment for use and equipment.Satiable cable work data demand.Can be used as to wait around the aircraft engine to connect under the high temperature particular surroundings and use cable, be applicable to it is the signal and the power transfer of Aeronautics and Astronautics field key position electronic devices and components.
The technical solution of the utility model: its structure is that the periphery with the stranded nickel-clad copper alloy wire conductor of electric wire cable strand machine is with wrapped two layers of polyimide composite band (PTFE/PI/PTFE) inner insulating layer of wrapped machine; The periphery of this inner insulating layer is the high temperature resistant alkali-free glass fibre external insulation layer with the braiding machine braiding; The periphery of this external insulation layer is with the wrapped lapping layer of mica tape, and the periphery of this lapping layer is the high temperature resistant alkali-free glass fibre woven protective layer with the braiding machine braiding.
The utlity model has following advantage: (1) insulation is adopted and is utilized wrapped and sintering process, adopts combined insulation, guarantees that cable has good electric property and mechanical performance.(2) external diameter is little, in light weight: reduce to lay the space, be convenient to install.(3) allowing working temperature for a long time is-55 ℃～+ 400 ℃.(4) high-temperature test: cable is at high temperature (400 ± 5 ℃), and 1h forwards low temperature (55 ± 3 ℃) to, 1h then in 5min.So circulation is continuous, totally 25 cycles.After the test, core and core, core and shielding, power frequency 50Hz, 500V, 1min does not puncture.(5) low-temperature test: cable is at low temperature-55 ℃, under the 20h environment.After the test, lead core and core, core and shielding, power frequency 50Hz, 500V, 1min does not puncture.(6) fire-retardant: the electric wire material therefor is fire-retardant, controls spreading of fire.(7) anti-interference: as to adopt the stainless steel wire woven shield.
The cable work data are following:
1) the long-term permission working temperature of cable :-55 ℃～+ 400 ℃;
2) to allow bending radius be 6 times of the outside diameter of cable to the minimum during cable laying.
This new product is high temperature resistant 400 ℃, have high temperature resistant, low temperature resistant, mould proof, anti-salt fog, anti-damp and hot, characteristics such as external diameter is little, in light weight, softness.
