Special cable for high-temperature environment and production equipment

The invention discloses a special cable for a high-temperature environment. The special cable comprises multiple groups of core wires, an insulating sleeve layer, a heat conduction cooling assembly and a heat insulation protection assembly. And the outer sides of the plurality of groups of core wires are sleeved with insulating sleeve layers. The heat conduction cooling assembly is arranged on the outer sides of the multiple sets of core wires in a sleeving mode and comprises heat conduction inner rings, the heat conduction inner rings are arranged among the multiple sets of core wires, the outer sides of the multiple sets of core wires are sleeved with heat conduction outer rings, and multiple sets of evenly-distributed heat conduction connecting plates are fixedly connected between the heat conduction inner rings and the heat conduction outer rings. And the heat-conducting inner ring, the heat-conducting outer ring and the multiple groups of heat-conducting connecting plates are matched to form a heat-insul
