Detailed descriptions：

The copper rod as the material of hard drawn bare copper wire adopts 350,000 tons of SCR - 7000 copper continuous casting and rolling production line from south of the U.S,has a stable and reliable product quality assurance. Individual wire adopts high speed continuous pulling and annealing process controlled by microcomputer to ensure stable and reliable product quality. The various performance meeting or exceeding national and EU standards can make sure safe operation in the use process.

The hard drawn bare copper wire made by Zhengzhou Huawei Metal Materials Co.,Ltd is stranded in the process of twisting and annealing , adopting unique patented technology .The finished products by stranded keeps round and straight ,tight in the structure .It is convenient for subsequent compression joint and extrusion processing, etc.

The commonly used structure of stranded copper wire is 7 strands, 12 strands,19strands、37strands,61strands ,etc.Its largest sectional area can be up to 400 sq. mm.

Hard drawn bare copper wires are applied to some extreme environment, such as damp, alkali soils, acid soil and caustic chemicals. They are widely used in electrification railway catenary system and lightning protection, grounded power station, signal tower, etc.In the mean time they can be as ground materials, downlead, and catenary wire, feeder, etc.They are widely used in power transmission and transformation station, power station,communication,railway, municipal infrastructure , petroleum and petrochemica and other engineering field with more higher requirements
