T/GDWCA 0018-2018 Armoring Process Operating Guidelines

Scope

Scope: This standard specifies the preparation work, precautions, operating procedures, and records for the armoring process. This standard applies to the process of installing steel strips or steel wires between the inner lining and outer sheath of wires and cables during the wire production process. When referring to armoring steel wires, please refer to the Specification for Weaving Process (see Appendix B for reference on steel wire selection). Main technical content: Precautions: 1. After each batch of armored cable cores is unloaded from the machine, carefully fill out the process cards and various reports to ensure the quality of semi-finished product transfer. 2. After each batch of armored cable cores is unloaded from the machine, verify again whether they meet the requirements and place them in designated locations. 3. In the event of a shift change, truthfully hand over the operation status and unfinished tasks to the incoming shift personnel. 4. The maximum gap between the armoring layers shall not exceed 50% of the steel strip width. The overlap between the upper and lower layers of steel strips shall not be less than 25% of the steel strip width. 5. If the manufacturing requirements cannot be met through process adjustments, the parameters in Appendix A can be used for debugging. 6. Hang the winding and armoring gears according to the process requirements, select appropriate traction speeds, and use suitable take-up reels and molds, etc. 7. The rewinding of steel strips should be tight. During the rewinding process, remove steel strips with interlayers, burrs, sand holes, and rust defects. 8. Start the equipment at low speed, run for a certain length, and check the winding and armoring parameters after stopping. At the same time, conduct a check on the operation of the equipment to ensure its integrity. After confirming that it meets the requirements, normal operation can resume. 9. During operation, do not leave the post without authorization. Patrol
