Reducing the cost of aluminum alloy cable with profiled wire drawing process
Mar 21, 2018

 "Special-shaped wire drawing system and cutter technology versatility, small and medium enterprises can be achieved through the process of upgrading products."


"April 8, 2015, Wuhan longitudinal cable Mold Co., Ltd. general manager Fang Jiangan in the" 2015 Wire and cable Industry Summit Forum-Henan Station, said.


In addition to its versatility, Fang Jiangan also introduces the five major features of the process in reducing costs when applied to aluminum alloy cables:


One, the same specifications, special-shaped wire stranded conductor outside diameter, can save insulating material, the special-shaped wire stranded conductor filling coefficient of more than 0.98, the same size conductor diameter smaller;


Second, the same model specification cable, the finished product outside diameter becomes smaller, can effectively save around the belt, armored belt, sheath material consumption; Third, profiled wire stranded aluminum alloy conductor smooth surface without burrs, single-line gap between small, extruded insulation in the spark test or withstand pressure test when the breakdown probability is small, applied to 10-500kv cable conductor on the partial discharge of small, can greatly improve the quality of enterprise cable, so that the product quality more stable, improve the product factory one-time pass rate,


Reduce potential product application quality issues and after-sales service costs;


Four, the same specifications to meet the GB gb/t3956-1997 the 2nd kind of stranded conductor minimum root number and resistivity requirements, under the premise of small-profile single root number, production of the same specifications than the circular compression structure required less, can improve production efficiency; Five, the twisted traction force is small, the production speed is quick, the special-shaped wire twist only needs to shape the mold to form instead of the circular tight pressure cold pull, stranded when the need for traction to increase production speed, can effectively reduce the delivery cycle of enterprises; to 13-mode high-speed sliding wire drawing machine and 54-frame stranding machine As an example: the drawing speed of profiled wire can reach 10m/s above,


The cutter speed reaches above 25m/min.
