Summary
The rapid expansion of HVDC transmission driven by the global energy transition is forcing cable manufacturers to move from project-based, low-volume production toward large-scale, repetitive manufacturing of identical extruded HVDC cables and standardized accessories.
Read more Read lessWhile current industry investments are largely focused on expanding manufacturing capacity, this paper demonstrates that capacity expansion alone is insufficient to control quality, cost, and delivery risks in high-volume production environments.
Using statistical process capability concepts, including Cp, Cpk, sigma level, and defect probability, the paper analyses extruded HVDC cable and accessory manufacturing processes under statistically stable conditions.
The paper concludes that the transition to high-volume manufacturing of extruded HVDC cables and accessories requires a strategic shift from capacity-driven expansion toward systematic process capability improvement. This shift is essential to ensure predictable quality performance, economic sustainability, and reliable delivery for future HVDC transmission projects.
