Abstract
The invention relates to a high-temperature-resistant low-noise cable, comprising: an armored cable, a first high-temperature plug and a second high-temperature plug, and the armored cable is composed of a high-temperature resistant wire, an outer mineral insulating layer, and a high-temperature plug from the inside to the outside. The alloy casing, the braided steel wire protective layer, and the high temperature resistant wire are respectively fixedly connected to the first high temperature plug and the second high temperature plug. The invention adopts many high-temperature-resistant materials, each part adopts sintering technology to form a whole, and there is no mutual friction between the parts, so that the cable can work in a high-temperature environment, and the noise is reduced.
Description
technical field [0001] The invention belongs to high-temperature signal transmission technology, and in particular relates to a high-temperature-resistant and low-noise cable. Background technique [0002] The measurement of aircraft engine parameters requires the participation of sensors such as high temperature pressure and vibration, so that the sensor signal transmission cable is often in a harsh environment with high temperature. Traditional organic insulated cables cannot work normally in high temperature environments, and are often accompanied by noise when working. Therefore, the aeroengine Parametric measurements require sensor signal transmission cables that can withstand high temperatures. Contents of the invention [0003] The invention provides a high-temperature-resistant and low-noise cable. The cable uses silicon oxide with a high melting point as the insulating material, and the outer armored sleeve is made of a high-temperature alloy material. Solve the ...
