Detailed descriptions:
Soft drawn bare copper wire mainly used for electrical devices in the power transmission and distribution and flexible connections in the electrical equipment, electrified railway catenary, water cooled cable soft copper conductor for industrial furnace,and also can used as earthling wire for electrical industry.
Soft drawn bare copper wire keeps soft and great resistance to bending, no broken strands and less strands .It accords with international electric commission IEC and European Union CE standard. Its reliable quality can ensure to use safely. They are all packed with iron wood spool to reduce the damage during transportation.
Soft drawn bare copper wire is flexible connection used for electrical equipment, electrical and electronic equipment, and element connection. There are two commonly used models TJR-95mm2 and 120mm2 in the railway catenary project.
Soft drawn bare copper wires made by Zhengzhou Hawai Metal Materials are widely used in electrified railway remodeling and new electrification railway catenary project, have gotten good reputations from construction companies. They are used in many national key projects and have achieved better results without appearing any problems under the process. We cooperate with many electric furnace factories ,the soft drawn bare copper wires as water-cold cable’s conductors have gotten widespread recognition and trust of customers.
