Quality Control
2XS(FL)2Y MDPE High Voltage 76/132 (145)kV Power Cable
Raw Material Test
Raw material testing is a fundamental quality control stage for the 2XS(FL)2Y MDPE High Voltage 76/132 (145)kV Power Cable. Conductors are tested for DC resistance, electrical conductivity, tensile strength, elongation, and dimensional accuracy to ensure efficient power transmission and mechanical integrity. XLPE insulation compounds are evaluated for dielectric strength, volume resistivity, thermal aging resistance, tensile strength, and elongation after aging. These tests confirm insulation stability under the high electrical stress typical of 145kV operation. Semi-conductive screen materials are tested for resistivity uniformity, surface smoothness, and adhesion compatibility with the XLPE insulation layers. The aluminum laminate (FL) moisture barrier is tested for thickness tolerance, bonding strength, corrosion resistance, and longitudinal water-blocking performance.
Process inspection
Process inspection ensures stable and consistent manufacturing of the 2XS(FL)2Y MDPE High Voltage 76/132 (145)kV Power Cable throughout all production stages. During conductor stranding and compaction, inspections verify conductor geometry, surface finish, 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 quality are measured in real time. Clean-room extrusion conditions are maintained to minimize contamination and reduce partial discharge risk. The application of the aluminum laminate screen is inspected to ensure correct overlap, bonding integrity, and continuous moisture barrier performance. MDPE sheath extrusion is monitored for uniform thickness, adhesion, and surface smoothness.
Finished Product
Finished product testing validates the safety, reliability, and performance of the 2XS(FL)2Y MDPE High Voltage 76/132 (145)kV Power Cable before delivery. Electrical tests include conductor resistance measurement, partial discharge testing, AC voltage withstand testing, and heating cycle tests in accordance with IEC standards for 145kV systems. Mechanical tests evaluate tensile strength, bending performance, and impact resistance to ensure installation reliability. Thermal tests confirm insulation stability under continuous operating temperatures. Water penetration and sheath integrity tests verify long-term moisture protection. Dimensional inspections confirm conductor size, insulation thickness, screen structure, and MDPE sheath thickness. Final visual inspection ensures correct marking, smooth surface finish, and defect-free construction.
Application
The 2XS(FL)2Y MDPE 76/132 (145)kV power cable is used for underground extra-high-voltage transmission in utility grids, substations, renewable energy connections, industrial complexes, and major infrastructure projects.
