Main Performance

XTAX series high-performance ultra-flexible transmission line is irradiated cross-linked ethylene tetraethylene copolymer (ETFE) insulation, high stranded silver-plated copper conductor for the conductor, so that the transmission line has a small outer diameter, light weight, flame retardant, aging resistance, mechanical strength, resistance to chemical erosion, and soft, easy to use and so on, can be well in line with the aerospace and airborne equipment on the requirements of the space and weight, to provide safety and reliability. Mechanical and chemical properties. Its performance is mainly manifested in:
1， small outer diameter, light weight: XTAX series transmission line conductor using ultra-fine multi-stranded grain, stranded outer diameter is small, the insulation and sheath thickness is designed to thin, so that the transmission line or harness of the outer diameter of the line is reduced by a lot, the weight than other ETFE structure conductor to reduce the weight of 10% to 20%.
2，combustibility: XTAX series transmission line insulation and sheath combustibility in line with the provisions of GJB773A, 30s after the fire, wire insulation should be self-extinguishing in 3s, the cable sheath should be self-extinguishing in 30s, the flame flame extension should be no more than 76mm.
3, resistance to chemical erosion: XTAX series of transmission line insulation and the sheath layer is not subject to the aircraft liquid corrosion, including: aqueous solutions, acids and alkalis, fuel oils, lubricants, cleaning products. Fuel oil, lubricating oil, detergent, coolant and antifreeze, high temperature and high humidity remain unaffected.
4， high and low temperature resistance: XTAX series transmission line by irradiation crosslinking of the insulation layer and sheath layer increases the polymer material high temperature resistance characteristics, temperature resistance of 200 ℃, and can be sustained through the 300 ℃, 7h accelerated aging test, this temperature is much higher than the melting temperature of the ETFE (270 ℃), these characteristics of the life of the characteristics and the characteristics of the melt does not make the transmission line has a very good thermal stability. At the same time, XTAX series transmission lines also have very good low-temperature resistance, maintaining good flexibility at temperatures as low as -65℃, and maintaining the same characteristics at temperatures lower than that.
5，excellent resistance to outer space radiation performance: XTAX series transmission line due to the insulation and sheath of fluorinated copolymers for crosslinking, the wire has a good oxygen stability, resistance to ionizing radiation in outer space, in the exposure of 5×10⁸ Rad (Si) radiation and still remain soft.
6， mechanical strength, excellent anti-cracking performance: the transmission line on the longitudinal question cut into and rub a very strong resistance to resistance, anti-cracking performance is extremely excellent is incomparable to other wires, which is the aircraft, spacecraft and airborne equipment need to be considered one of the important indicators.
7, high reliability: XTAX series transmission lines in harsh environments to provide high reliability services, which is mainly reflected in the ability to withstand the test of integrated environmental conditions, they include high temperature, high humidity, strong sunlight, dry heat, cold, sand, rain, low air pressure, mold, salt spray, oil mist, chemicals
nuclear neutron and r-ray radiation, vibration, impact, bending, friction, twisting and winding and other direct and indirect effects.
8, easy to operate: XTAX series transmission line has a very easy to operate characteristics, very easy to use automated equipment marking or manual marking, very easy to strip the wire, hanging tin and terminals, you can use the printing and inkjet printing is not ready for the group marking. The insulators do not melt or shrink easily when the wire is soldered, making it easy to handle.

Product Construction
The insulation of XTAX series high-performance ultra-flexible transmission lines is divided into single-layer insulation and double-layer insulation. Single-layer insulation structure is most suitable for the need to save space and reduce the weight of the place; double-layer insulation structure is in line with the requirements of its strength in order to prevent the installation of mechanical damage caused by damage to the design, the inner layer of insulation and the outer layer of insulation with a different color distinction.
