FR-N30XA8E-R 18/30(36)kV Cable Gen to NF C 33-226 - Cu/XLPE/MDPE

XLPE insulation compounds undergo comprehensive physical and electrical testing. Tests include melt flow index, density measurement, thermal aging resistance, and dielectric strength verification. High-temperature aging simulations are performed to ensure insulation stability under continuous operating conditions. Contamination control inspections are conducted to prevent insulation defects that could affect cable reliability. MDPE sheath materials are tested for tensile strength, elongation at break, shrinkage, and resistance to environmental stress cracking. Additional tests assess moisture resistance and UV stability to ensure reliable performance in underground and outdoor environments. Each batch of raw materials used for FR-N30XA8E-R 18/30kV Cable is fully traceable through material identification, inspection records, and certificates of conformity. 

XLPE insulation extrusion is strictly controlled by monitoring extrusion temperature, pressure, line speed, insulation thickness, and concentricity. Online spark testing is applied to detect insulation defects in real time. Samples are taken at defined intervals for hot set testing, elongation testing, and cross-linking degree verification to confirm insulation quality. The cabling stage focuses on correct lay length, phase identification, and mechanical stability of the triplex structure. Alignment and bonding between cores are inspected to ensure structural integrity. MDPE sheathing inspection includes sheath thickness measurement, surface smoothness evaluation, and adhesion testing. Automated diameter monitoring systems provide continuous feedback, ensuring consistent sheath quality. All inspection data are recorded and reviewed to guarantee that FR-N30XA8E-R 18/30kV Cable meets NF C 33-226 requirements throughout production.

Finished Product Testing verifies that FR-N30XA8E-R 18/30kV Cable fully complies with NF C 33-226 before delivery. Mechanical testing evaluates tensile strength, elongation, bending performance, and impact resistance. Environmental tests such as thermal cycling, heat aging, and water penetration simulate long-term operating conditions to verify durability. Dimensional verification confirms conductor size, insulation thickness, and sheath thickness are within specified tolerances. Visual inspection checks sheath surface quality, marking accuracy, and overall workmanship. All test results are compiled into final inspection reports and certificates of conformity. Only cables that pass all finished product tests are approved for shipment, ensuring reliable field performance of FR-N30XA8E-R 18/30kV Cable.
