Quality Control
LiYY Flexible Control Cable - PVC Multi-Core Unshielded Cable
Raw Material Test
Raw Material Test forms the foundation of quality assurance for the LiYY Control Cable. Incoming copper rods undergo comprehensive chemical and mechanical testing to ensure high conductivity and flexibility. PVC insulation and sheath compounds are tested for flame retardancy, thermal aging, insulation resistance, and mechanical properties. Surface and dimensional inspections are conducted to eliminate material defects. Only raw materials that fully satisfy all specification requirements are approved for the production of the LiYY Control Cable. This strict raw material validation ensures the final cable delivers consistent electrical performance, mechanical flexibility, and durability required for industrial control applications.
Process inspection
Process Inspection throughout the manufacturing of the LiYY Control Cable ensures precision and consistency. Wire drawing and stranding processes are monitored to maintain exact conductor diameter and uniform twisting. Insulation extrusion is controlled for consistent thickness and concentricity. Core assembly and final sheathing undergo real-time tension and diameter checks. Mid-process electrical and mechanical sampling tests are performed. Any deviation from parameters triggers immediate corrective measures. These detailed process controls protect the integrity and performance of the LiYY Control Cable, resulting in a flexible, high-quality control cable suitable for demanding industrial environments.
Finished Product
Every completed reel of LiYY Control Cable undergoes thorough Finished Product testing. Dimensional checks verify overall diameter, insulation thickness, and sheath uniformity. Electrical tests including high-voltage, insulation resistance, and conductor resistance validate performance. Mechanical tests assess flexibility and tensile strength. Full visual inspection ensures a defect-free surface. All tests follow VDE 0812 and IEC 60227 standards with complete traceability records. Packaging and marking are also verified. Only the LiYY Control Cable that passes 100% of these final inspections is approved for shipment.
