Background technique
Coaxial cable refers to that there are two concentric conductors, and conductor and shielded layer share the cable in same axle center.It is most common
Coaxial cable be made of the copper conductors that insulating materials is isolated, the outside of inner insulating material be another layer of ring shaped conductor and
Its insulator, then entire cable is encased by the sheath of polyvinyl chloride or teflon material.Coaxial cable is divided into four from inside to outside
Layer: center copper wire, plastic insulation, reticulated conductive layer and wire outer skin, center copper wire and reticulated conductive layer form current loop.
Insulating material in existing coaxial cable uses single material, there is a problem of that compression strength is low, wear-resisting property is poor, limits
The application of coaxial cable is made, therefore, it is necessary to improve to the prior art.
