A wire consisting of a central core surrounded by one or more layers of closely spaced yarns, twisted in opposite directions.

2. Direction of lay (alternative definition)

The torsion direction is defined as the right or left direction.

3. Surface

4. Joints

• On the cored wire and on any ropes, there shall not be any joints in any way, during the twisting process.
• During the torsion process, it is not allowed to weld a single aluminum wire in order to achieve the specified wire length.
• Joints shall be made by contact welding, contact welding and then cold forging or cold pressing (see note 1) and other approved methods.
