Heat-resistant TPU (Thermoplastic polyurethanes) insulation non-asbestos diesel engine signal shielding cable

The invention discloses a heat-resistant TPU insulation non-asbestos diesel engine signal shielding cable. The heat-resistant TPU insulation non-asbestos diesel engine signal shielding cable comprises a bunch-stranded tinned copper conductor, a TPU insulation layer, a polyester tape taped inner covering layer, a tinned copper wire inner shielding layer, packing mediums, a polyester tape taped outer covering, a tinned copper wire outer shielding layer and a TPU outer protective sleeve layer. A layer of TPU insulation layer is wrapped outside the bunch-stranded tinned copper conductor to form insulating wire cores, the insulating wire cores are pair-twisted to sequentially cover the polyester tape taped inner covering layer and the tinned copper wire inner shielding layer to then form shielding wire groups, the plurality of shielding wire groups are pair-twisted to form a cable core, a layer of tinned copper wire outer shielding layer covers the cable core, the packing mediums are filled between the cable core
