Abstract
The utility model relates to a reinforced type broadband data indoor cable for polyolefin insulation PVC sheaths, and belongs to a novel telephone cable. The utility model is composed of a copper conducting wire, reinforced steel wires, insulation layers and sheath layers. The utility model is characterized in that a center part is provided with the copper conducting wire, and the periphery is provided with the 4 to 19 reinforced steel wires; the outside is covered with the polyolefin insulation layers and forms insulation wires; the two insulation wires are twisted and form a group of wire pairs, and the outer layers of the wire pairs are provided with the PVC sheath layers; the reinforced type broadband data indoor cable for polyolefin insulation PVC sheaths can be composed of one to four groups of wire pairs. After the reinforced type broadband data indoor cable for polyolefin insulation PVC sheaths is tested, the conductor tensile strength is at 930N, the attenuation constant is at 2.47dB/100M, thereby, the utility model meets the requirements of top wire data transmission and facsimile. The utility model has the characteristics of reasonable design, simple structure and long service life. The utility model has wide application ranges, and can be used for entering net through broadband.
Description
Technical field
The utility model belongs to novel telephone cable, relates to the reinforced wideband data house lead in of a kind of polyolefin insulation pvc sheath cable.
Background technology
At present, the telephone cable that domestic tradition is used, skin is the restrictive coating of flat, the centre is an insulating barrier, establishes copper covered steel wire in insulating barrier.This telephone cable can satisfy the phone line, but because it exists signal attenuation big, can not satisfy the requirement of broadband access network data.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is for satisfying the requirement of broadband access network transfer of data, fax, improve the tensile strength of telephone cable, the reinforced wideband data house lead in of a kind of polyolefin insulation pvc sheath cable being provided.
The reinforced wideband data house lead in of the utility model polyolefin insulation pvc sheath cable content Description:
The reinforced wideband data house lead in of the utility model polyolefin insulation pvc sheath cable, by: copper conductor, reinforcement steel wire, insulating barrier, restrictive coating are formed, it is characterized in that: be a copper conductor in the centre, be provided with 4～19 on every side and strengthen steel wire, the external packets polyolefin insulation layer is made insulated wire, it is right that 2 insulated wires strand is made one group of line, and skin is the pvc sheath layer;
The reinforced wideband data house lead in of polyolefin insulation pvc sheath cable can be by 1～4 pair of line to forming.
The reinforced wideband data house lead in of the utility model polyolefin insulation pvc sheath cable, after tested: conductor tensile strength is 930N, attenuation constant is 2.47dB/100m, satisfy the requirement of broadband access network transfer of data, fax, have characteristics reasonable in design, simple in structure, long service life, its applied range can be used for the broadband and network.
