211, third conductor 31 and the 4th conductor 41；In practical stranding process, need to be carried out according to above-mentioned twisting pitch, as equipment without
The pitch, please by the maximum value of most close twisting pitch；
S2, core wire are made: being coated outside the first conductor 111a by high-density polyethylene respectively using plsitive mold
Insulating layer made from alkene material obtains the first inner core 111；
Cladding is by 45P environment-friendly polyvinyl chloride material outside second conductor 211, third conductor 31 and the 4th conductor 41
Expect insulating layer obtained, respectively obtains the second inner core 21, third core 30 and the 4th core 40；
By 2 first inner core, 111 pair twists and tissue paper is coated outside 2 first inner cores 111, is obtained in first
Core 11；
4 first core 11 are twisted and coat 60P black environmental protection polychlorostyrene second outside 4 first core 11
Insulating layer made from alkene material obtains the first core 10；
By 2 second inner core, 21 pair twists and tissue paper is coated outside 2 second inner cores 21, obtains the second core
20；
3 the 4th cores 40 are closed and are twisted；
The temperature of extruding zone is preferably 160 ± 20 DEG C, needs to carry out FAA first article assurance before batch production, needs to measure line halfway
Diameter, and core is both needed to stay at coiling iron pan empty position end to end, facilitates inspection；
S3, core wire are wrapped: centered on first core 10, and by 5 second cores, 20,3 thirds
Core 30 and 3 the 4th cores 40 are circumferential twisted along first core 10, and made from the external wrapped tissue paper in
Sheath 50；
S4, be extruded outside: by the way of squeezing will the oversheath 60 as made from 60P black environment-protective polychloroethylene material it is equal
It is even to be coated on outside the sheath 50；
In actual production process, each production procedure of strict control is needed, it is ensured that product environmental protection.Wherein, it is extruded the temperature of section outside
Degree is preferably 160 ± 20 DEG C, needs to carry out FAA first article assurance record before batch production, needs to measure line footpath halfway, and twisted with hand
Product line judges whether bias；The both ends end to end of every product line are both needed to stay in above the fold, facilitate inspection and sampling；In addition,
It needs verification lettering content whether correct before outer jacket outer surface lettering, guarantees cable processing quality, improves qualification rate.
In conclusion implementing a kind of signal transmission environment-friendly cable provided by the invention and preparation method thereof, beneficial to effect
Fruit is: the first core of the environment-friendly cable, the second core, third core and the 4th core insulating layer and oversheath
It is made of polyvinyl chloride or high-density polyethylene material, manufactured cable is very environmentally friendly, avoids cable poison gas in a fire
Generation, reduce the reproduction pollution on the environment of cable；And the environment-friendly cable strict control is twisted stranding distance, can subtract
The generation of few cable vortex, improves shielding properties, avoids the adverse effect transmitted to signal,
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
