The aluminum laminate (FL) moisture barrier is tested for thickness tolerance, bonding strength, corrosion resistance, and longitudinal water-blocking performance. MDPE sheath compounds undergo mechanical property testing, including tensile strength, elongation, abrasion resistance, environmental stress crack resistance, and UV resistance. All raw materials used in the 2XS(FL)2Y cable are subject to strict incoming inspection and full traceability. Only materials that fully meet technical and quality specifications are released for production.
Process inspection
Process inspection ensures consistent and controlled manufacturing of the 2XS(FL)2Y MDPE High Voltage 64/110 (123)kV Power Cable across all production stages. During conductor stranding and compaction, inspections verify conductor geometry, surface quality, and concentricity. During XLPE insulation extrusion and cross-linking, critical parameters such as extrusion temperature, pressure, and line speed are continuously monitored. Insulation thickness, eccentricity, and surface smoothness are measured in real time. Clean-room extrusion conditions are maintained to minimize contamination and reduce partial discharge risk. In-process inspections include spark testing, dimensional checks, and electrical monitoring. All process data is recorded and reviewed to ensure compliance with production standards and consistent cable quality.
Finished Product
Finished product testing verifies the safety, performance, and reliability of the 2XS(FL)2Y MDPE High Voltage 64/110 (123)kV Power Cable prior to delivery. Electrical tests include conductor resistance measurement, partial discharge testing, AC voltage withstand testing, and heating cycle tests in accordance with IEC requirements for 123kV systems. Mechanical tests assess tensile strength, bending behavior, and impact resistance to ensure installation reliability. Thermal tests confirm insulation stability under continuous operating temperatures. Water penetration tests and sheath integrity tests verify long-term moisture protection. Only cables that successfully pass all finished product tests are approved for shipment.
