Abstract:
     This wire has three advantages: the specific gravity of steel core is less than copper core, the tension strength is stronger and the cost is lower. The copper facing advantages to skin effect, meanwhile it advantages to weld, thus, basically overcomes the defect of conjunctions. With antiager plastic coated sheath, it can help the lifetime of wire elongating to 10-15 years more, which is 2-3 times that is galvanized. Therefore, the maintained works of serviceman will be greatly reduced, and large amount of fund also will be reduced.
