Layer parcel PVC or low smoke and zero halogen sheath material, constitute cable finished product.
As preferred：Described 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 external diameter control of cable is within 7.3mm.
A kind of preparation method of the unmasked type anti-interference data cable of non-metallic material cladding cable core as described above, it is described
Preparation method comprise the following steps：
1）Single line makes：With copper bar after wire drawing and annealing, extrusion molding is simultaneously cooled down, and conductor is covered HDPE and is insulated into single line, so
Single line take-up afterwards；
2）Pair twist makes：Single line unwrapping wire, 2 single lines are twisted into twisted-pair feeder with rational pitch, then pair twist take-up；
3）Stranding makes：Pair twist unwrapping wire, 4 pairs of twisted-pair feeders are according to certain order stranding, and with conventional cross in the middle of 4 pairs of twisted-pair feeders
Skeleton is separated, and is wrapped up outside cable core with New Type Material, then stranding take-up；
4）Sheath makes：Squeezed outside stranding unwrapping wire, total cable core and cover PVC or low smoke and zero halogen plastic sheath, constitute cable finished product.
As preferred：Described preparation method also includes：
Step 1）In, wire drawing is passed through by 2.6mm copper bars, conductor covering HDPE insulate, and single line conductor is 0.565mm, outer insulation diameter
In 1.0-1.1mm；
Step 3）Described in cable core outside New Type Material resist to be interior containing a kind of nonmetallic shielding of nonmetallic suction ripple material
Disturb material band；
Step 4）In：Squeezed outside total cable core and cover PVC or low smoke and zero halogen plastic sheath, constitute cable finished product, finished product external diameter 6.8mm.
The present invention, can be significantly using a kind of interior anti-interference material band of nonmetallic shielding for containing nonmetallic suction ripple material
Degree absorbs radio magnetic wave, and to play jamproof effect, due to the particularity of material, electrostatic will not be produced during use；
And under the pitch design of reasonably optimizing, it can guarantee that by while cross-talk index, can also effectively reduce cross bone between cable
The size of frame, it is ensured that the external diameter of whole cable is within 7.0mm.
The present invention, which has, can reach cross-talk index between cable, reduce crossing skeleton and cable is outer by size, meet normal
Used under rule occasion, the features such as effectively reducing cable cost.
