Abstract
The invention belongs to the technical field of communication wire rods and provides an improvement structure with more than six types of cables. The improvement structure with more than six types of cables comprises an inner layer, a plurality groups of twisted pair wires, layer and an outer layer from inside to outside. Each group of twisted pair wires comprise two core wire sets which are twisted into a spiral shape. Each core wire set comprises conductors and insulating layers which are respectively coated on the outer side of the conductors. An isolation support is arranged in the inner layer. A support distance from a centre of a circle to the outer side of the isolation support is larger than or equal to the distance from the center of the circle to the twisted pair wires. The improvement structure with more than six types of cables has the advantages of conducting support on the outer layer through the isolation support, enabling changing distance between gaps to become stable, guaranteeing stability of transmission and greatly improving performance. Due to the fact that the isolation support enables the conductors to maximize the surrounding air gaps, the improvement structure with more than six types of cables provides stable impedance performance, improves attenuation performance and guarantees high transmission performance of the cables.
