Description
Technical Field
The utility model relates to a communication cable technical field, concretely relates to two twisted data communication net twines.
Background
The communication cable is used for near-distance audio communication and long-distance high-frequency carrier and digital communication and signal transmission, and is a communication line formed by a cable core formed by twisting a plurality of mutually insulated conducting wires or conductors and an outer sheath for protecting the cable core from moisture and mechanical damage. The conventional six types of unshielded twisted pair data communication cables only adopt the flame retardance of the added sheath material to improve the flame retardance of the cables, and the insulation adopts a single-layer structure and a layer of HDPE, so that the high flame retardance requirement of special occasions is difficult to meet; and the cable core adopts solid HDPE cross skeleton to keep apart, and the HDPE material is easily fired, and solid HDPE cross skeleton is harder moreover, is not convenient for be under construction. Therefore, it is necessary to design a new technical solution to comprehensively solve the problems in the prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a two twisted data communication net twines can effectively solve the high fire-retardant requirement that is difficult to satisfy special occasion and the harder problem of solid HDPE cross skeleton that exists among the prior art.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a twisted-pair data communication network cable comprises a cable core and a sheath layer coated outside the cable core, wherein a conductor and a foaming cross-shaped framework are arranged in the cable core, a first insulating layer is coated outside the conductor, a second insulating layer is coated outside the first insulating layer to form double-layer insulating wires, every two double-layer insulating wires are twisted in pairs to form conductor groups, and the conductor groups are isolated by the foaming cross-shaped framework.
Further, the first insulating layer is an HDPE insulating layer.
Further, the second insulating layer is a flame-retardant polyethylene insulating layer.
The further scheme is that the conductor is of a six-type conductor structure and is made of an oxygen-free copper wire material.
In a further scheme, the sheath layer is a nylon protective sleeve.
The twisted-pair data communication network cable provided by the technical scheme adopts a double-layer insulation structure of the first insulation layer and the second insulation layer, the inner layer adopts the HDPE insulation layer, and the outer layer adopts the flame-retardant polyethylene insulation layer, so that the flame retardance of the communication network cable can be effectively improved; the cable core is isolated by a cross-shaped framework made of foamed flame-retardant polyethylene, so that the flame retardance of the communication network cable can be effectively improved, and the problem that the cable is relatively hard as a whole is solved.
