Background

At present, the inner conductors of the mainstream coaxial cables in the market are generally divided into two types, namely a single inner conductor and a twisted inner conductor. The single inner conductor means that the inner conductor of the coaxial cable is composed of a copper cable, the surface of the single inner conductor is round and smooth, and the structure is stable, so that the attenuation of the coaxial cable is low, and the electrical property is more stable. However, individual inner conductors also have inherent drawbacks such as their poor flexibility, high weight, and susceptibility to breakage during repeated bending.

The twisted inner conductor refers to a copper conductor formed by twisting a plurality of copper cables together under a certain rule. When the copper conducting cable is bent, each conducting cable disperses the bending stress of the copper conducting cable, so that the coaxial cable is stronger in structure flexibility and more flexible to use due to the design of the twisted copper conducting cable. However, the current mainstream twisted inner conductors are usually twisted naturally, and compared with a single inner conductor with the same diameter, the twisted inner conductor has a smaller surface area, and when a high-frequency signal is transmitted, the generated resistance is larger, so that the attenuation of the coaxial cable made of the twisted inner conductor is relatively larger.
