Electrician Copper Wire Blank
■ Product standard: GB/T3952-1998
According to the requirement of wide customer our company can produce copper
single wire and bared wire, etc
with any specification.
The diameter of wire blank and its allowable deviation should be in conformity
with the regulations in following list:
Diameter mm |
6.0~6.35 |
>6.35~12.0 |
>12.0~19.0 |
>12.0~19.0 |
>25.0~35.0 |
Allow deviation |
±0.5-0.25 |
±0.4 |

■ Torsion characteristic
T1, T2 and T3 brand copper wire with 6.0~22.0mm of diameter should carry out torsion test.
After torsion it should not appear
the defects such as wrinkle, impurity, etc. The bright metallic crack is not as the judged
basis of reject.
