About special line drawing and stranding process cable conductor seventeen q&a

A, line drawing and stranding technology have any requirements on production equipment?

A: does the company have a water tank wire drawing machine, sliding large drawing machine, machine wire drawing machine in any kind of wire drawing machine and 54 box of stranding machine or fork winch.

Two large drawing machine, sliding type (also called linear large drawing machine which can control the shape of the different line?

A: you can control T line, flat wire and SZ line;

Three, copper large drawing machine can even pull back even alien copper wire?

A: large copper can high speed control, annealing part slightly improve and adjust the process parameters can;

Four, special line drawing and stranding need equipment modification?

Answer: the need to visit your company equipment, 80% enterprise equipment do not need to reform, some quite obsolete equipment need to change appropriately.

Five, the different line conductor structure meet the national standards?

Answer: "alien stranded cable conductor line and its production method" has obtained national invention patent, patent no. 201410338703.5, the inventions change the GB (aluminum alloy) conductors of aluminium or copper structure size design, meet the national standard of GB/T3956-2008 the second minimum stranded conductor root number and resistivity change under the premise of twisted structure design of molding line, production process, the design variable is not round wire and wire drawing control according to different specifications by the reasonable design of alien (tile) line, stranding through unique pre-twist process and plastic mold making different wire twisted shape.

Six, the process can produce special line stranded conductor size range is how much?

A: it is the actual production of the specifications of the tested 25 was ~ 1250 was.

Seven, profiled wire drawing speed can reach?

A: water tank wire drawing machine in 5 ~ 10 m/s, sliding machine type and large drawing machine motor control speed 8 to 18 m/s;

Eight, profiled wire winding speed can reach?

Stranding speed is completely determined by the production equipment; General is 20 ~ 30 m/min;

Nine, 50 square and the small specification line with 54 box of stranding machine or fork stranding machine on the production speed is slow, and overqualified?

A: in view of the small specification different wire stranding, I have a high speed small companies to develop this warping machine is designed for stranding 50 square and the following special line with small specification, equipment price is only 100000 yuan of /, stranding speed in 40 ~ 60 m/min;

Ten, alien stranded conductor development cost budget probably how many?

A: the company implements the conductor structure design, mold processing, the production process technical guidance and training services; To develop each specifications cable conductor, on average, 2.5 ~ 30000 yuan. Another special wire development according to the development specifications accounting.

Eleven, profiled wire twisted cable conductor development success guaranteed?

A: our company technical personnel to understand the status of the equipment your company can reply will be clear after your company equipment production; Once signed and expenditure service contract, guarantee successful mass production for your company, if you don't succeed unconditional refund;

Twelve, wire drawing and stranding technology application range have?

A: the technology can be applied to aluminum alloy cable conductor, cable conductor, high pressure in the copper/aluminum cable conductor, carbon fiber composite conductor, wire twisted overhead conductors;

13, wire drawing and stranding technology used in high pressure copper conductor advantage have?

A: in short based on existing general process can reduce the cost of 2-5%, mainly under the precondition of the same resistance is more economical copper consumption, conductor diameter smaller than circular press 5% - 5%, save the same voltage grade shielding materials, insulation materials, filling amount, armored steel belt, sheath material;

14, wire drawing and stranding process compared with other production process characteristics?

Answer: special line drawing and stranding process small investment, small risk, flexibility, high utilization rate of equipment and application of products, production specifications of product (s) is not restricted;

15, alien stranded conductor bending performance?

Answer: special line stranded conductor structure accord with standard of GB/T3956-2008 different specifications and the smallest number of design, national standard stipulated minimum number is in order to ensure the cable conductor could satisfy the requirement of special environment in the installation process bending performance; So the alien stranded conductor line meet standard requirements, the bending performance is good will not become the bottleneck of the technical application promotion;

16, alien stranded conductor heat dissipation performance worse than circular compression heat?

Answer: alien stranded conductor line high fill factor does not mean less heat dissipation performance, cable conductor copper or aluminium (alloy) belong to high heat conduction coefficient of the material, and special line stranded conductor diameter smaller than circular press conductors only 2% to 5%. If choose different line from the Angle of heat dissipation stranded conductor advanced technology problem, that is nonsense; If so say that foreign submarine cable are changed different line stranded conductor, national uhv overhead conductors are stranded conductor), choose different line of today's most advanced overhead conductors in the structure of the carbon fiber composite core is different line stranded conductor; The advanced technology of cable technology USES different line stranded conductor are not progress backwards; In turn of special shape line stranded conductor cable diameter smaller, in cable trench laying cable between greaten distance of the cable heat, cable current carrying capacity can be improved;

17, wire drawing and stranding process application if there is a real case?

Answer: different wire drawing and stranding technology popularization and application since 2014, now has more than 20 enterprises implement different line stranded cable conductor volume production; The representative enterprises in this field are the group company (liaoning province), change especially electrician (deyang) cable, cable, jiangsu long Wu Hanhong couplet peak cable, cable anhui Pacific group, anhui nanyang cable group, chong DE cable, hebei with Asia aluminum, cable, strong Jiang Sudong stake, Germany's son cable cut, etc
