A cable provided with a thermal insulation shield that dissipates heat fast comprises a cylindrical cable body (9) arranged in the thermal insulation shield, and the thermal insulation shield comprising an upper thermal insulation shield (8) and a lower thermal insulation shield (7). The cover walls of the upper thermal insulation shield (8) and the lower thermal insulation shield (7) comprise respective bottom walls (80, 70) and side walls at two sides of the bottom walls (80, 70); and the bottom walls (80, 70) are in contact with two dome portions of the cable body (9) which are opposite to each other on the diameter of the cable body (9). Cooling fluid channels (81, 71) extending long the cover walls are arranged in the cover walls; and heat discharge holes (200) parallel to the cooling fluid channels (81, 71) are arranged in the bottom walls (80, 70). Twenty one or more heat discharge holes (200) are provided; and the two side walls of the lower thermal insulation shield (7) are inserted between the two side walls of the upper thermal insulation shield (8). |
