Abstract
A kind of the unmasked type anti-interference data cable and preparation method of non-metallic material cladding cable core, the cable includes 4 pairs with conventional crossing skeleton twisted-pair feeder arranged apart, it is characterized in that each pair twisted paired conductor specification is single copper wire 30AWG 22AWG and strands conductor 30AWG 22AWG, single copper wire twisted-pair feeder outer insulation diameter is 0.90 1.26mm, and stranded copper wire twisted-pair feeder outer insulation diameter is 0.70 1.35mm；Outer layer of cable core is coated with non-metallic material, and outermost layer parcel PVC or low smoke and zero halogen sheath material, form cable finished product；It has the features such as reaching cross-talk index between cable, reducing outside crossing skeleton and cable by size, meet to use under conventional occasion, effectively reduce cable cost.
Description
Technical field
The present invention relates to a kind of unmasked type anti-interference data cable of non-metallic material cladding cable core, suitable for number
According to the transmission of information in center routing and broadband access network system, belong to communication cable technical field.
Background technology
Traditional unmasked surpasses six class data cable structures and is generally：The cored wire of 8 solid polyethylene of bare copper conductor outer cladding,
Separated among 4 pairs of twisted-pair feeders with a crossing skeleton, carry out stranding, outermost layer is by the use of polyvinyl chloride or low smoke and zero halogen material outside
Quilt.In order to reach this important indicator of cross-talk between cable, traditional unmasked surpasses six class data cables due to no anti-interference layer of shielding,
4 pairs of twisted-pair feeders must be separated as far as possible with crossing skeleton, therefore skeleton size wants bigger, thick and solid, while when oversheath is extruded
Saw-tooth-type structures are used, to ensure the distance between cable cable core structure, so as to reduce cross-talk between cable.Such knot
For structure since crossing skeleton is big and thick and solid, the reason such as sheath sawtooth pattern, whole outer diameter of cable will reach 9.0mm, cable producing efficiency
It is low, it is costly；Also very inconvenient during practice of construction, wiring space utilization rate is relatively low.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of follow-on, can reach between cable
Cross-talk index, reduces outside crossing skeleton and cable by size, meets to use under conventional occasion, effectively reduce cable cost
Non-metallic material cladding cable core unmasked type anti-interference data cable and preparation method.
The purpose of the present invention is come what is completed, a kind of non-metallic material coats the unmasked of cable core by following technical solution
Type anti-interference data cable, it includes 4 pairs with conventional crossing skeleton twisted-pair feeder arranged apart, each pair twisted paired conductor
Specification is single copper wire 30AWG-22AWG and strands conductor 30AWG-22AWG, single copper wire twisted-pair feeder outer insulation diameter are
0.90-1.26mm, stranded copper wire twisted-pair feeder outer insulation diameter are 0.70-1.35mm；Outer layer of cable core is coated with non-metallic material, outermost
Layer parcel PVC or low smoke and zero halogen sheath material, form cable finished product.
As preferred：The single line conductor is 0.565mm, and single copper wire twisted-pair feeder outer insulation diameter is in 1.0-1.1mm；Electricity
The total outside diameter control of cable is within 7.3mm.
Brief description of the drawings
Fig. 1 is the cross-sectional structure schematic diagram of the present invention.
Embodiment
Below in conjunction with attached drawing, the present invention will be described in detail：Shown in Fig. 1, a kind of non-metallic material of the present invention
The unmasked type anti-interference data cable of cable core is coated, it includes 4 pairs with conventional crossing skeleton 1 twisted-pair feeder arranged apart, institute
The each pair twisted paired conductor specification stated is single copper wire 30AWG-22AWG and strands conductor 30AWG-22AWG, single copper wire
23 outside diameter of multiple twin line insulating layer is 0.90-1.26mm, and stranded copper wire twisted-pair feeder outer insulation diameter is 0.70-1.35mm；Outside cable core
Layer non-metallic material layer 4 coats, and outermost layer parcel PVC or low smoke and zero halogen sheath material layer 5, form cable finished product.
Single line conductor of the present invention is 0.565mm, and single copper wire twisted-pair feeder outer insulation diameter is in 1.0-1.1mm；Cable
Total outside diameter control is within 7.3mm；Tear rope 6 is equipped between being gone back between the non-metallic material layer 4 and sheath material layer 5.
