A soft high temperature resistant signal cable includes a cable core, a shield layer, a flame retardant layer, a woven layer and an outer protective jacket layer. The shield layer is wrapped around the outside of the cable core, a thermal insulation layer is arranged between the shield layer and the flame retardant layer, the woven layer is wrapped around the outside of the thermal insulation layer, the outer protective jacket layer is arranged on the outer side of the woven layer. The corresponding thermal insulation layer, flame retardant layer, outer protective jacket layer, inner protective layer and flame retardant insulation material on the inner side can effectively enhance the high temperature resistance of the cable, while ensuring the flame retardant effect, so as to effectivelyimprove the flame retardancy and the temperature insulation, so that the stability of the cable can be improved to ensure the corresponding use in the special environment, and the shield layer on theinner side and the corresponding insulation layer and the like are designed to carry out corresponding protection on the signal transmission of the cable, so that the cable has strong creativity and is suitable for popularization.
