Abstract
The utility model discloses a composite communication cable with a stretch resistant function. The composite communication cable comprises a fiber unit, a first communication twisted wire pair, a second communication twisted wire pair, a first electric power twisted wire pair, a second electric power twisted wire pair and a five-pointed star-shaped frame. The fiber unit is composed of four communication fibers located inside a loose tube. The first communication twisted wire pair is formed by twisting four first copper conductors coated with insulating layers in a two-pair way and used for information communication. The first electric power twisted wire pair is formed by twisting four second copper conductors coated with insulating layers in a two-pair way and used for electric power transmission. A metal layer is plated and coated on the surface of the five-pointed star-shaped frame. The aluminum layer of an aluminum foil layer is located on the inner side and thus electrically contacts the metal layer of the five-pointed star-shaped frame. A steel wire is tightly wrapped on the outer surface of the aluminum foil layer to form an armor layer. A sheath layer is wrapped on the outer surface of the armor layer. External electromagnetic interference can be effectively prevented from entering the cable. Meanwhile, internal signals are prevented from being transmitted out and interfering the running of other equipment. Echo loss, characteristic impedance and overhearing attenuation of a digital cable can be significantly improved.
