Problems solved by technology

At present, the commonly used low-impedance cables have a single structure, usually only one layer of shielding layer, one layer of heat dissipation layer and one layer of insulation layer, although they have the basic performance of low-impedance cables
However, thermal insulation failure often occurs, causin

Abstract

A low impedance cable, include an out protective layer, coolant layer, insulating layer, central cooling layer, Central cable core and cable core, A layer of coolant is arranged on that inn side of the outer protective layer, The insulating layer is arranged on the inner side of the coolant layer, the filling layer is arranged on the inner side of the insulating layer, the cable core is arranged on the inner side of the filling layer, the central cable core is arranged on the inner side of the filling layer, the central cooling liquid layer is arranged on the inner side of the central cable core, the coolant layer and the central cooling liquid layer are both liquid hydrogen or liquid nitrogen, and the central cable core is pure copper material. The low-impedance cable has good heat dissipation ability, can better resist rapid high-voltage impact, avoids the insulation failure problem caused by long-term operation of the cable, ensures the normal operation of the low-impedance cable, lowers the line power consumption, improves the quality of the low-impedance cable, and meets the use requirements of the low-impedance cable.

Description

technical field [0001] The invention relates to the technical field of cable design and manufacture, in particular to a low-impedance cable. Background technique [0002] With the continuous improvement of the level of science and technology, the level of cable design and manufacturing technology has also been greatly improved. A cable is usually composed of several or several groups of wires, made of one or more mutually insulated conductors and an outer insulating protective layer, and is used to transmit power or information from one place to another. Or a cable similar to a rope twisted by several wires or groups of wires, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating coating. The cable has the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, c...
