| Function | The wire torsion and wrapping testing machine is used to evaluate the plastic deformation capacity of metal wire under torsion and to reveal surface and internal defects. It also serves as a testing machine for assessing the toughness and coating adhesion of galvanized steel wire used in overhead stranded conductor structures and reinforcement applications. |
| Application | The equipment provides reliable data for both wire manufacturers and end users. |
| Standard | This testing machine conforms to GB/T 2976-2004 / ISO 7802:1993 "Metallic materials—Wire—Wrapping test". |
| ISO 7800 | Metallic materials—Wire—Unidirectional torsion test |
| ISO 9649 | Metallic materials—Wire—Bidirectional torsion test |
| ISO 7802 | Metallic materials—Wire—Wrapping test |
