Further illustrate, to during, in 10-20mm, the speed of twisted wire is 50-60m/min, institute to the strand for lay control
Wrapping angle control is stated at 45-50 °.
Further illustrating, cables manufacturing using the conductor that is made for being directly used in shielding and insulation processing, or with copper bar or
Aluminium bar, and by its wire drawing to suitable diameter, it is then stranded（Kink is integral）Into cable conductor.
The cables manufacturing of the stranded manufacture conductor of those wire drawings must comply with basic but important technique, to ensure that conductor is obtained
Suitable physical property and electric property.Because drawing process makes metal produce processing hardening, therefore wire rod after wire drawing is usual
Must heat to obtain appropriate physical property, this technique is annealing.Annealing can be realized by sensing heating process.At this
During individual, heat is produced by sensing the electric current on twisted wire, and improve the temperature of conductor to correct annealing temperature.
In addition twisted wire can also be placed into furnace box and realizes annealing.Annealing can simultaneously influence the physically and electrically performance of twisted wire, therefore
Must with caution be operated in annealing process and monitored.Must regularly be tested to ensure that the characteristic of twisted wire meets wanting for specification
Ask.Stranded conductor is completed by many single lines of twisting, there is polytype twisting（Or it is stranded）Pattern.Although twisting process
It is relatively easily accomplished, but must carefully operates, ensures that single line is not damaged and stranded coefficient during stranded（It is single
Twisted number of times on bit length）Correctly.Moisture in conductor is extremely out of favour, because moisture can cause to grow water tree in insulation
So that cable premature breakdown, may also lead to cable connector premature breakdown.May make water in manufacture, installation or running
Into conductor, it is considered as using the conductor of stop water.
