Prysmian E3X technology is a ceramic coating that can be added onto new and pre-existing power transmission cables, improving their thermal emissivity, so they heat up 30% less, have 25% lower resistive losses, and/or can carry 25% increased currents.
This data-file locates the patents underpinning E3X technology, identifies the materials used, and finds a strong moat around the technology.
In 2018, Prysmian acquired General Cable in a $3bn deal, apparently outbidding China’s Hengtong, plus Nexans and NKT, who were also interested.
Prysmian thus gained access to General Cable’s E3X technology, which has exciting potential for reconductoring transmission lines.
E3X is a thin yet durable ceramic coating, with 0.9x emissivity factor and 0.2x solar absorptivity factor, that can be applied to the outside of power transmission cables, thereby helping the conductors to dissipate heat.
This matters as hot cables are more resistive and also tend to sag causing electric
