Embodiment Construction

[0019] According to the accompanying drawings, the conductor is a compact stranded conductor, which is concentrically stranded on a wire and cable stranding machine with multiple strands of silver-plated copper monofilament or copper alloy monofilament, and is extruded through a mold after stranding;

[0020] The insulating layer is made of cross-linked-ethylene tetrafluoroethylene copolymer cross-linked material, and the ultra-thin cross-linked-ethylene tetrafluoroethylene copolymer cross-linked material is extruded on a high-temperature extruder by selecting a suitable extruded tube die, and is electronically Accelerator irradiation cross-linking;

[0021] The shielding layer is made of silver-plated copper wire, which is wound in one direction on a braiding machine or winding machine;

[0022] The sheath layer is made of cross-linked-ethylene tetrafluoroethylene copolymer cross-linked material, and the ultra-thin cross-linked-ethylene tetrafluoroethylene copolymer cross-lin...

Abstract

The invention provides an ultra-light low-frequency wire or cable for aerospace use. The ultra-light low-frequency wire or cable for aerospace use is characterized by comprising a single core or multiple cores, wherein each core comprises a compressed light conductor which is formed by twisting multiple silver-plated copper monofilaments or silver-plated copper alloy monofilaments; an ultrathin insulating layer which is extruded by a crosslinking-tetrafluoroethylene ethylene copolymer material through high-temperature extrusion equipment and is crosslinked by irradiation through an electron accelerator is arranged on the periphery of each conductor; a shielding layer which is unidirectionally wound by multiple silver-plated copper wires is arranged on the periphery of each insulating layer; and a light sheath layer which is extruded by a crosslinking-tetrafluoroethylene ethylene copolymer through high-temperature extrusion equipment and is crosslinked by irradiation through the electron accelerator is arranged on the periphery of the shielding layer. The ultra-light low-frequency wire or cable has the advantages that by the light conductors, the ultrathin insulating layers and sheath layer and the unidirectionally wound shielding layer, the ultra-light low-frequency wire or cable has the characteristics of light weight and small outer diameter, simultaneously has the advantages of extreme low temperature resistance, high temperature resistance, irradiation resistance, vacuum atom oxygen resistance, high insulating cutting strength, vacuum air escape resistance and the like, is low in content of harmful gases generated by insulated and non-metal materials combustion and escape, and is suitable for signal transmission, control transmission and energy transmission between electrons and electric appliances, in a low-frequency environment, on a spacecraft, a space station and other aerospace equipment in an aerospace environment.

Description

technical field [0001] The invention proposes a C55 series ultra-light low-frequency wire and cable for aerospace, which is suitable for signal transmission, control transmission and energy transmission between electrons and electrical appliances in a low-frequency environment on spacecraft, space stations and other aerospace equipment. It has excellent mechanical properties, electrical properties and aerospace environment resistance (radiation resistance, vacuum atomic oxygen resistance, etc.), and can be used for a long time in the range of -100 to +200 °C. Background technique [0002] With the highly integrated and complex functions of aerospace equipment, it is required that the weight of the wire and cable network can continue to be reduced in order to reduce the weight of the entire aerospace equipment. But the C55 conventional wire currently used cannot meet the demand for smaller weight. The existing products are based on GJB / 773A-2000 "Fluoropolymer Insulated Wire...
