Abstract

The invention provides a communication cable production process, which is characterized in that: the communication cable production process comprises the following processing steps: 1) drawing a copper wire into copper thread of which the bare wire has a 0.56 millimeter diameter and using the copper thread as a cable core; 2) feeding the cable core into a plastic extruding machine to perform plastic insulated cladding of the cable core; 3) coiling the cable core clad with the plastic for insulation and placing the coil into a pair twisting machine, wherein untwisting and pair twisting processes are adopted to ensure the precision and stability of the twist pitch of thread pairs and reasonable twist pitch design, control twisting rate and finished cable twisting rate and reduce cost; 4) making the coat of the twisted cable by using a coat extruding machine; 5) placing the coated cable in a coiling packaging machine to coil the cable; and 6), testing the performance of the prepared cable on a comprehensive testing machine, and packaging and warehousing the qualified cable. When the process is used to produce the communication cable, the data transmission is stable and production cost can be reduced greatly.

Description

A kind of communication cable production process

Technical field

The present invention relates to a kind of production technology of the communications cable.

Background technology

At present, along with the continuous development of network, the requirement to the transfer of data dielectric behavior in comprehensive wiring system also improves constantly.Select 6 class wiring systems, it becomes simply high speed data transfer, and new network application platform not only is provided, and has also promoted digital voice and the Video Applications service quality to desktop greatly.Wherein twisted-pair feeder is as a kind of transmission medium of cheap, function admirable, in comprehensive wiring system, be widely used in horizontal wiring, the transmission speed that it provides can be up to 1000Mbps, not only can be used for transfer of data, can also be used for voice and multimedia transmission, therefore twisted-pair feeder is a kind of indispensable transmission medium, and how when not influencing data transmission quality, the production cost that further reduces twisted-pair feeder becomes new research topic.

Summary of the invention

The object of the present invention is to provide a kind of communication cable production process, not only transfer of data is stable to use this explained hereafter communications cable, and can reduce production costs greatly.

Technical program of the present invention lies in: a kind of communication cable production process is characterized in that: process according to the following steps:

1) select for use copper cash to pull into the copper wire that bare wire is φ 0.56mm, as core;

2) core is packed into plastic extruder carries out the coating of core plastic cement insulation;

3) will coat the core sabot that plastic cement insulate, the pair twister of packing into, by back twist and twist on technology, retention wire is accurate, stable to lay, and Haul Rate and stranding Haul Rate are controlled in reasonably lay design, reduce cost;

4) stranded cable is coated by the outer quilt that is extruded machine outward and carries out cable;

5) cable that will be covered to complete is outward put into lopping packing machine coiled web-like;

6) cable of making is carried out performance test on the integration test machine, conformance with standard can be packed warehouse-in.

The invention has the advantages that: 1, pitch has improved signal, stability of data transmission greatly than rationally;

2, core plastic cement overcoat adopts the coating method of degree of depth compacting pressing insulation, has improved activity coefficient, organizes steam etc. to the both sides diffusion, stops the extension of external impairment, and makes line to a Stability Analysis of Structures, has further improved signal, data transmission stability;

3, reasonably the lay design reduces Haul Rate, stranding Haul Rate, has saved raw material, has reduced production cost.

Embodiment

A kind of communication cable production process is characterized in that: process according to the following steps:

1) select for use copper cash to pull into the copper wire that bare wire is φ 0.56mm, as core;

2) core is packed into plastic extruder carries out the coating of core plastic cement insulation;

3) will coat the core sabot that plastic cement insulate, the pair twister of packing into, by back twist and twist on technology, retention wire is accurate, stable to lay, and Haul Rate and stranding Haul Rate are controlled in reasonably lay design, reduce cost;

4) stranded cable is coated by the outer quilt that is extruded machine outward and carries out cable;

5) cable that will be covered to complete is outward put into lopping packing machine coiled web-like;

6) cable of making is carried out performance test on the integration test machine, conformance with standard can be packed warehouse-in.

Described Haul Rate is 1.016, and described stranding Haul Rate is 11.2 meters.

In production technology of the present invention, at first select for use the copper cash of high-quality to pull into the copper wire that bare wire is φ 0.56mm, diameter commonly used at present is φ 0.6mm, calculates with the every case of 300m, every case can be saved the 0.8kg copper wire;

The Haul Rate of 1.03m commonly used in producing at present is adjusted into 1.02m, the stranding Haul Rate is adjusted into 11.2m, according to said method, every case cable is saved 3.76 yuan of cable expenses behind stranding, and it is about 13% that production cost descends, and can save production cost significantly.

Claims (2)

1. communication cable production process is characterized in that: process according to the following steps:

1) select for use copper cash to pull into the copper wire that bare wire is φ 0.56mm, as core;

2) core is packed into plastic extruder carries out the coating of core plastic cement insulation;

3) will coat the core sabot that plastic cement insulate, the pair twister of packing into, by back twist and twist on technology, retention wire is accurate, stable to lay, and Haul Rate and stranding Haul Rate are controlled in reasonably lay design, reduce cost;

4) stranded cable is coated by the outer quilt that is extruded machine outward and carries out cable;

5) cable that will be covered to complete is outward put into lopping packing machine coiled web-like;

6) cable of making is carried out performance test on the integration test machine, conformance with standard can be packed warehouse-in.

2. a kind of communication cable production process according to claim 1 is characterized in that: described Haul Rate is 1.016.
