Embodiment 1

[0021] please see figure 1 , figure 1 It is essentially a schematic cross-sectional view of the present invention, which shows the cable core 1, the first wrapping layer 2 wrapped outside the cable core 1 and the sheath layer 3 outside the first wrapping layer 2, wherein: the cable core 1 Including five data line pairs 11, second and third wrapping layers 12, 13, central reinforcement 14 and ground wire 15, each data line pair 11 includes a pair of conductors 111 and a coating layer covering each conductor 111 112. The conductor 111 is made of tinned stranded copper wire with a single wire diameter of 0.12mm, and the coating layer 112 is a fluoroplastic coating layer, that is, the material is fluoroplastic as the coating layer 112. The data line pairs 11 are twisted to each other, and the adjacent data line pairs 11 are twisted to each other around the central reinforcement 14. When each data line pair 11 is twisted by itself, each data line pair 11 is wrapped around eac...

Embodiment 2

[0024] The picture is omitted, the number of data line pairs 11 is changed to six pairs; the diameter of the monofilament of the conductor 111 is changed to 0.5mm; the thickness of the aluminum foil is changed to 0.035mm; the polyester wrapping tape that will serve as the third wrapping layer 13 Change the thickness of the ground wire 15 to 0.030㎜; change the diameter of the tinned stranded copper wire constituting the ground wire 15 to 0.2㎜; change the thickness of the polyester wrapping tape 141 wrapped around the central reinforcement 14 to 0.03㎜; The thickness of the first wrapping layer 2 (polyester wrapping tape) is changed to 0.03 mm. All the other are the same as the description to embodiment 1.

Embodiment 3

[0026] The picture is omitted, the number of data line pairs 11 is changed to four pairs; the diameter of the monofilament of the conductor 111 is changed to 0.1mm; the thickness of the aluminum foil is changed to 0.04mm; the polyester wrapping tape that will serve as the third wrapping layer 13 change the thickness of the tinned stranded copper wire that constitutes the ground wire 15 to 0.1mm; change the thickness of the polyester wrapping tape 141 wrapped around the central reinforcement 14 to 0.025mm; The thickness of the first wrapping layer 2 (polyester wrapping tape) is changed to 0.02mm. All the other are the same as the description to embodiment 1.

Abstract

A communication cable for ducts belongs to the technical field of wires and cables. The communication cable comprises a cable core, a first lapped covering and a sheath layer, the cable core comprises a plurality of data wire pairs, and each data wire pair comprises a pair of conductors and covering layers respectively covering the conductors. The communication cable is characterized in that: thecable core also comprises second lapped coverings, third lapped coverings, a central reinforcement and earth wires, each data wire pair is lapped by one of the second lapped coverings, the second lapped coverings are lapped by the third lapped coverings, the number of the earth wires is equal to the number of the data wire pairs, the earth wires respectively accompany one of the data wire pairs, the central reinforcement is positioned in the center of the cable core, glass fibers are bundled together and covered by a polyester lapped tape to form the central reinforcement, and the data wire pairs surround the central reinforcement and are stranded on the central reinforcement. The communication cable has the advantages that: the communication cable can meet the requirement of large-angle laying in ducts; the communication cable can be adapted to environmental conditions well; and the communication cable can prevent outside moisture from entering the data wire pairs, thus guaranteeing the communication effect.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a communication cable for pipelines. Background technique [0002] Communication cables for pipelines are usually called special cables, and the reason why they are called special cables is that due to the special environment of underground exploration operations, the technical requirements for this kind of cables are extremely strict, and the specific performance is not limited to The following aspects: First, because the communication cable needs to pass through the 90° pipeline with a length of tens of meters or even hundreds of meters, and the diameter of the pipeline is slightly larger than the diameter of the communication cable, the communication cable is required to have excellent strength and resilience; second, it is necessary to ensure ideal high and low temperature resistance; third, because communication cables are used in a deep unde...
