Скачать или смотреть 8.7/15kV Power Cable CU-XLPE-STA-PVC 3*70mm2 Manufacturing Process | ZD CABLE

Watch the manufacturing process of the 8.7/15kV, 3-core 70mm² copper core power cable produced by Henan Zhong Dong Cable (ZD CABLE).

Manufacturing Process
1. Conductor Refining: 99.99 % oxygen-free copper rods are drawn and annealed, with a conductivity exceeding IEC 60228 standards, and the 70mm² cross-sectional area error is less than ±0.5%.
2. Three-layer Protection: XLPE cross-linked insulation (with a temperature resistance of 105℃) + galvanized steel tape armor (with a compressive strength of more than 4000N/5cm) + PVC outer sheath, passing a 500,000 times bending fatigue test.
3. Intelligent Production: Fully automatic argon arc welding continuous rolling technology, online X-ray inspection for insulation layer defects, with a defect rate of less than 0.001%.
