Super gentle cable, this super gentle cable includes: the inner conductor, set up in inner conductor outlying insulating layer, the insulating layer winds the package for the low -density polytetrafluoroethylene area that has air gap, set up in weaving layer in the insulating layer outlying, set up in the outer weaving layer of interior weaving layer outlying, set up in outer weaving layer outlying restrictive coating. The utility model has the characteristics of communication frequency is high, attenuation constant is low, the compliance is good, and under conditions such as mechanical bending, insulating dielectric constant changes very for a short time, has stable insulation system.
