To guide and standardize the operation methods and procedures of employees to improve the quality and efficiency of operation, as well as twist maintenance and maintenance of machines.

Scope of 2.

Applicable to all staff of strand workshop

3. Define

Stranded wire: the high-speed circular operation of capstan, driven by the traction force of the winding shaft, a number of copper wires are twisted together in the same direction, which can be divided into positive twisted (i.e., S twisted) and reverse twisted (i.e., Z twisted).
