Quality Control and Testing Standards for AISG Cables

1, Quality Control Process for AISG Cables
The quality control of AISG cables is a systematic project that covers all aspects from raw material procurement, production process control to finished product inspection. The following are the key quality control steps:
Raw material quality control
Conductor material: High purity oxygen free copper or tin plated copper is selected to ensure good conductivity and corrosion resistance.
Insulation material: High performance polyvinyl chloride (PVC), polyethylene (PE) or cross-linked polyethylene (XLPE) are used to ensure electrical insulation performance and high temperature resistance.
Shielding material: Use copper foil, aluminum foil, or woven copper mesh to provide effective electromagnetic shielding and reduce interference.
Sheath material: Choose wear-resistant and corrosion-resistant materials, such as chlorinated polyolefin (CPE) or low smoke halogen-free (LSZH) materials, to enhance the durability and safety of the cable.
Production process control
Process control: Advanced manufacturing technology and equipment are adopted to ensure the manufacturing accuracy and consistency of cables. Including key processes such as conductor drawing, insulation extrusion, shielding weaving, and sheath extrusion.
Online detection: Implement online detection during the production process, such as conductor resistance testing, insulation resistance testing, shielding effect testing, etc., to promptly detect and correct potential problems.
Finished product testing
Appearance inspection: Check the cable identification, insulation integrity, and sheath smoothness to ensure compliance with design requirements.
Electrical performance testing: Conduct tests on conductor resistance, insulation resistance, capacitance, inductance, etc. to verify the electrical performance of the cable.
Mechanical performance testing: including tensile strength, bending performance, wear resistance, and other tests to ensure the mechanical strength and durability of the cable.
Environmental adaptability testing: Conduct high temperature, low temperature, humidity, salt spray and other tests to verify the stability and reliability of cables in various harsh environments.
2, Key testing items and standards for AISG cables
To ensure the quality of AISG cables, a series of key testing projects need to be carried out and corresponding international or industry standards followed. The following are the main testing items and standards:
Electrical performance testing
Conductor resistance test: According to the IEC 60228 standard, measure the DC resistance of the cable conductor to ensure the conductivity of the conductor material.
Insulation resistance test: According to IEC 60332-1 standard, measure the insulation resistance of the cable insulation layer and verify its electrical insulation performance.
Capacitance and inductance testing: Measure the capacitance and inductance of cables to evaluate their impact on signal transmission.
Mechanical performance testing
Tensile strength test: According to ISO 6892 standard, test the tensile strength of the cable to ensure its stability under tensile conditions.
Bending performance test: Conduct a bending test on the cable according to IEC 60228-2 standard to evaluate its bending performance.
Wear resistance test: Using ISO 4649 standard, test the wear resistance of cable sheath to ensure its durability in long-term use.
Environmental adaptability testing
High temperature test: Place the cable in a high temperature environment and test its stability and performance changes under high temperature conditions according to IEC 60068-2-2 standard.
Low temperature test: Place the cable in a low temperature environment, follow the IEC 60068-2-1 standard, and evaluate its performance under low temperature conditions.
Humidity test: According to the IEC 60068-2-78 standard, place the cable in a high humidity environment and test its moisture resistance.
Salt spray test: According to IEC 60068-2-11 standard, place the cable in a salt spray environment to evaluate its corrosion resistance.
Other tests
Flame retardant performance test: According to the IEC 60332-3 standard, test the flame retardant performance of the cable to ensure its safety under fire conditions.
Electromagnetic compatibility testing: Follow CISPR standards to test the electromagnetic compatibility of cables and reduce electromagnetic interference.
3, The Importance of Quality Control and Testing
The quality control and testing of AISG cables are of great significance for ensuring the stability and reliability of communication networks. Through strict quality control processes, it is possible to ensure that the raw material quality, production process control, and finished product quality of cables meet the design requirements. Comprehensive testing projects and standards can verify the electrical performance, mechanical performance, and environmental adaptability of cables, ensuring their continuous and stable operation in practical applications. This not only helps improve the reliability and stability of communication networks, but also reduces maintenance costs and operational risks caused by cable failures.
