▎ 摘　　要

NOVELTY - The cable has a jacket (8) formed with an outermost layer, a copper strip interlocking armored layer (7) and an isolation layer (6). An outer layer of a cable core is formed with an intermediate layer and a ceramic polyolefin insulating layer (3). A graphite thin conductor (9) is formed with an annular surface of the ceramic polyolefin insulating layer. An annular array is formed in the ceramic polyolefin insulating layer. The cable core is arranged in the isolating layer. A glass fiber rope (4) is formed with the isolation layer and connected with a glass fiber belt (5). USE - Graphene ultra-soft mineral insulated fire-proof cable. ADVANTAGE - The cable has better conductive effect, and improves cable signal transmission conductive ability and fire-proof capability. DETAILED DESCRIPTION - The copper strip interlocking armored layer is a copper layer or copper-aluminum alloy layer or aluminum layer. An INDEPENDENT CLAIM is also included for a cable wire core preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a graphene ultra-soft mineral insulated fire-proof cable.
