Gemini: Most standard industrial or power cables are produced in much shorter segments (a few hundred meters to a couple of kilometers) because of weight, transport logistics, and spool limitations. Being able to continuously extrude, insulate, armor, and test a high-voltage power cable up to roughly 40 kilometers in a single unbroken stretch requires specialized manufacturing plants and massive logistical handling (such as Prysmian’s advanced vertical continuous vulcanization lines and specialized cable-laying vessels like the Leonardo da Vinci).

So while it does happen for major cross-border submarine or underground interconnector projects to minimize vulnerable joints, 40 km factory lengths represent the absolute pinnacle of high-tech manufacturing rather than an everyday occurrence.
