The invention discloses an oxidation-resistant low-temperature-resistant cable. The oxidation-resistant low-temperature-resistant cable comprises an outer protection sleeve, a heat preservation layer,a liquid nitrogen cooling layer, a protection layer, a high-voltage insulation layer and an insulation protection sleeve; the surface of the outer protection sleeve is provided with a model mark; a braided shielding layer is arranged inside the outer protection sleeve, and the heat preservation layer is arranged inside the braided shielding layer; the liquid nitrogen cooling layer is arranged inside the heat preservation layer; the protection layer is arranged in the liquid nitrogen cooling layer; the high-voltage insulation layer is arranged in the protection layer; the insulation protectionsleeve is arranged inside the high-voltage insulation layer; a filling layer is arranged in the high-voltage insulation layer; power lines are installed inside the insulation protection sleeve; and ground wires are arranged in the protection layer. According to the cable, a low-temperature-resistant anti-oxidation structure is prepared by adopting the outer protection sleeve which is prepared from a low-temperature-resistant silicone rubber material, so that the cable has very high anti-oxidation corrosion resistance, high elasticity and scratch resistance, longer service life and higher economic benefit.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to an oxidation-resistant and low-temperature resistant cable. Background technique [0002] A cable is a rope-like cable that is usually twisted by several or groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Has a highly insulating covering. Cables have the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, and aluminum alloy cables. Wait, they are all composed of single-strand or multi-strand wires and insulating layers, used to connect circuits, electrical appliances, etc. At present, most cables have reduced oxidation resistance and corrosion resistance, and low tem...
