More Information
Summary:The utility model discloses coupling coaxial cables and a detection and security system provided with the coupling coaxial cables, and aims to provide the coupling coaxial cables which are long in service life, stable in structure and stable in transmission and to provide the detection and security system which is provided with the coupling coaxial cables and is simple in structure, high in sensitivity and accurate in locating. Each coupling coaxial cable comprises an outer conductor (3), wherein the outer conductor (3) is a net-shaped conductive layer woven through metal wires; a magnetic through hole woven through the metal wires is formed in the net-shaped conductive layer; and the weaving tightness of the net-shaped conductive layer is determined according to the laying length of the coupling coaxial cable, the attenuation constant of transmitted high-frequency electromagnetic waves, and needed amount of coupling electromagnetic fields. The detection and security system provided by the utility model furth
