High electric conductivity copper stranded wire for middle east I.Brief introduction of high electric conductivity copper stranded wire Stranded bare copper wire to be used for circuit ground connections as well as machinery and equipment grounding Stranded Bare Copper wire Standard: *designed according to any international standard as requested. Construction: *Solid or Concentric stranded bare Soft or Annealed Copper. Installation:
*Soft drawn copper conductor can be installed in air. The superiority of high electric conductivity copper stranded wire . 1.Favorable electrical conductivity to reduce the loss of the current . 2.Well mechanical and physical properties with certain tensile strength ,stretching rate to meet the requirement of placing ,installation and using 3.Certain ductility so that easy to process. 4.Good heat conductivity to keep the heating balance 5.Nice certain corrosion resistance . Note: It is one material which can be substituted as pure copper stranded cables The specification of high electric conductivity copper stranded wire
