Abstract

The invention belongs to the field of cable technology, and discloses a composite electric power cable having a communication channel. The composite electric power cable is prepared by wrapping a communication conductor with a cable outer layer. The communication conductor is a wire core formed by twisting copper wires. The insulating outer layer of the cable is high in insulating performance, corrosion resistance, flame retardant property and mechanical property. The invention is simple in preparation process and suitable for industrial production on a large scale.

Description

technical field [0001] The invention belongs to the field of cable technology, and in particular relates to a composite power cable with a communication channel. Background technique [0002] The communication cable consists of a plurality of mutually insulated wires or conductors to form a cable core, and a communication line with a sealed sheath on the outside. Some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, it is divided into symmetrical, coaxial and integrated cables; according to its function, it is divided into field and permanent cables (underground and submarine cables). The transmission frequency band of the communication cable is wider, the communication capacity is larger, and it is less affected by external interference, but it is not easy to repair. Can transmit telephone, telegram, data and image etc. Communication cables re...
