Thermotolerant corrosion-resistant flexibility-resistant cable

Abstract

The invention relates to a thermotolerant corrosion-resistant flexibility-resistant cable belonging to the technical field of special cables and comprising a cable core, a shielding layer and an outer sheath, wherein the shielding layer is arranged outside the cable core, the outer sheath is arranged outside the shielding layer, the cable core comprises a lead, a filler and a wrapping layer, and the lead comprises a conductor and an outer coating layer coated outside the conductor. The thermotolerant corrosion-resistant flexibility-resistant cable is characterized in that the filler is aramid fiber and surrounds the lead; the conductor is formed by stranding nickel-chromium alloy wires or nickel-aluminum alloy wires; the outer coating layer and the wrapping layer are both Teflon; and the outer sheath is irradiation crosslinking fluorubber. The thermotolerant corrosion-resistant flexibility-resistant cable has ideal beading resistance and excellent performances of high-temperature resistance, chemical corrosion resistance and radioactive ray resistance and also has a feature of environmental protection.

Description

technical field [0001] The invention belongs to the technical field of special cables, and in particular relates to a high-temperature-resistant, corrosion-resistant and flexure-resistant cable, which is applied to occasions such as high-speed electrified trains, nuclear power facilities and high-temperature environments. Background technique [0002] As cables used in high-speed electrified trains, nuclear power facilities and high-temperature environments such as high-temperature furnaces, etc., not only require good physical properties such as flex resistance, but also require excellent chemical corrosion resistance such as heat resistance, oil resistance and radioactivity resistance And so on, so people refer to the cables used in the above occasions as high-end cables. [0003] China Utility Model Patent Authorization Announcement No. CN201408572Y discloses a high-temperature super-flexible cable with copper mesh braiding layer, mica tape layer and irradiation cross-lin...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned prior art has common strengths, that is, it has good achievements in high temperature resistance and corrosion resistance, but there is a common deficiency, that is, the flex resistance cannot meet the applicant's above-mentioned requirements such as power cables for electrified high-speed trains. Use requirements, and it is difficult to meet the use requirements such as automobile starter connection cables, heat-resistant motor output cables, etc.
