▎ 摘 要
NOVELTY - The utility model claims a bear fire electric conduction wire, comprising conductor, insulation layer, filler, screening layer, glass fiber layer, sheath, armoured layer and outside sheath, said insulation layer is composed of single cable core covered on outside conductor, screening layer wrapped on the cable core, covered on the gap inside; screening layer from inside to outside in turn covered glass fiber layer, sheath, armoured layer and outside sheath, provided with the graphene layer, thereof, between in said screening layer of conductor and insulation layer, glass fiber layer, protective sleeve, armoured layer and thickness ratio between outside sheath is 1-2: 3-4: 2-3: 1-2: 3-4. The utility model is fire bear high electric conduction wire, 3 hours no combustion in 750 degrees C flame, comprising bear good fire performance, at the same time with the super-conductive performance, widely used for petroleum, chemical industry, metallurgy, electric power equal work, with the good practicability.
