3+1 Cores Copper Cable CU/XLPE/PVC 0.6/1kV
Raw Material Test
All materials used in the manufacture of 3+1 Cores Copper Cable CU/XLPE/PVC 0.6/1kV undergo strict quality verification before production. Copper rods are tested for conductivity, purity, tensile strength, elongation, and surface quality to ensure optimal electrical performance. Chemical composition analysis is conducted using advanced spectrometry equipment. XLPE compounds are evaluated for dielectric strength, thermal endurance, volume resistivity, and cross-linking consistency. PVC compounds are inspected for tensile strength, flexibility, elongation, flame-retardant performance, and aging resistance. Additional testing includes moisture content analysis, contamination inspection, dimensional verification, and batch consistency evaluation. Each material lot is sampled and tested according to established quality procedures.
Process inspection
During production of the 3+1 Cores Copper Cable CU/XLPE/PVC 0.6/1kV, every manufacturing stage is closely monitored to ensure consistent quality. Copper wire drawing operations are inspected for conductor diameter, roundness, and surface finish. Stranding processes are checked to verify conductor compactness and flexibility. During XLPE insulation extrusion, critical parameters such as temperature, pressure, insulation thickness, and concentricity are continuously monitored. Core laying and assembly inspections ensure proper cable geometry and core positioning. PVC sheath extrusion is controlled through regular measurements of sheath thickness and concentricity.
Finished Product
Every reel of 3+1 Cores Copper Cable CU/XLPE/PVC 0.6/1kV undergoes comprehensive final testing before shipment. Conductor resistance testing confirms electrical conductivity and compliance with IEC standards. Insulation resistance and AC voltage withstand tests verify electrical safety and dielectric integrity. Dimensional inspections ensure conductor size, insulation thickness, and sheath thickness meet specified requirements. Mechanical evaluations include tensile strength, elongation, and sheath adhesion testing. Heat aging and thermal deformation tests assess long-term operational reliability. Visual inspections verify cable marking, core identification, sheath appearance, and packaging quality. Additional flame-retardant and environmental resistance tests may be conducted upon request.
