Heatproof TPU insulating asbestos-free diesel engine shielding signal cable

The utility model discloses a heatproof TPU insulating asbestos-free diesel engine shielding signal cable comprising twisted tinned copper conductors, TPU insulating layers, polyester tape inner wrapping layers, tinned copper wire inner shielding layers, a filling medium, a polyester tape outer wrapping layer, a tinned copper wire outer shielding layer, and a TPU outer sheath layer. Each twisted tinned copper conductor is wrapped in the TPU insulating layer to form an insulating wire core. Multiple insulating wire cores are twisted and then are successively wrapped in the polyester tape inner wrapping layer and the tinned copper wire inner shielding layer to form a shielding wire group. Multiple shielding wire groups are twisted to form a cable core. The cable core is wrapped in the polyester tape outer wrapping layer. The filling medium is filled between the cable core and a total wrapping layer. The total wrapping layer is wrapped in the tinned copper wire outer shielding layer. The TPU outer sheath layer is extruded on the tinned copper wire outer shielding layer. The heatproof TPU insulating asbestos-free diesel engine shielding signal cable has advantages of heat and high temperature resistance, a good anti-interference capability, oil resistance, and corrosion resistance.
