Abstract

The invention discloses an ultra-high temperature resistant low-noise cable, comprising a plurality of strands of pure nickel stranded conductors which are wrapped in the same pure nickel wire woven main shielding layer, wherein a composite outer protecting layer is wrapped outside the pure nickel wire woven main shielding layer; a semiconducting composite inner shielding layer, a composite insulating layer, a semiconducting composite outer shielding layer and a pure nickel wire woven sub-shielding layer are sequentially wrapped outside each strand of pure nickel stranded conductor. The ultra-high temperature resistant low-noise cable solves the problem that the low-noise cable has no ultra-high temperature resistance property in the prior art, solves the contradiction between low noise and high-temperature resistance requirement of the cable by the material selection, cable structure and proper process design, and provides a low-noise cable which can be used at 1000 DEG C for a long term.

Description

technical field [0001] The invention relates to a low-noise cable, in particular to a low-noise cable that can work in an ultra-high temperature environment of 1000°C for a long time. Background technique [0002] Under the action of external factors such as bending, vibration, impact, temperature change, etc., the cable itself will generate a certain amount of electrostatic signal (or called cable structure noise), and cables with cable structure noise less than 5mV are usually called low-noise cables. Low-noise cables are required for the measurement of tiny signals in many fields such as industrial measurement and control, medicine, and national defense. At present, the more common low-noise cables include polyethylene insulated low-noise cables, F46 insulated low-noise cables, radiation-resistant low-noise cables, low-capacitance low-noise cables, watertight low-noise cables, etc., but there is a lack of ultra-high temperature-resistant low-noise cables .
