Ampacimon Acquires Underground Cable Monitoring Specialist Diael

As the monitoring of high-voltage cables and substations has become key in grid optimization,  the combination of Ampacimon’s (high voltage cables) and DIAEL’s product lines (underground power cables) will allow both companies to extend their service range in that market segment. 


Last summer, Korys, Noshaq, Creos and Gesval participated in a capital increase with Ampacimon to provide funding to accelerate its growth, either organically via innovative projects or through acquisitions. The acquisition of DIAEL is a first step in that growth strategy.

Cables and high-voltage substation equipment are key assets in high- and medium-voltage grids, as they allow utilities to reduce their environmental footprint, while still connecting more renewables and moving towards mass electrification. DIAEL’s partial discharge monitoring solutions use a combination of high-performance sensors and advanced analytics, in particular their noise filtering technology.

With the acquisition, Ampacimon will further extend its service range into condition monitoring. DIAEL brings advanced capabilities in underground cable partial discharge monitoring, both in hardware and analytics, which complements Ampacimon’s strengths in overhead lines monitoring.

Frederic Vassort, CEO of Ampacimon, said in the Jan. 13 statement, in part: “We identified DIAEL as a company sharing a very similar DNA to ours quite some time ago: we both come from university spin-offs, we both enjoy strong ties with national grid operators and we both share innovation in electricity grids as one of our core values. Adding underground cables monitoring technologies to our overhead line offering is a most logical strategic step for Ampacimon, as the share of underground cables in grids keeps increasing. This new combination of Ampacimon and DIAEL will bring grid operators a wider range of products and services to enable them to safely optimize the use of their infrastructure to enable a greener energy transition.”

Javier Ortego, general manager at DIAEL, said in the statement, in part: “From the very beginning we have been working alongside Ampacimon with different applications but within the same environment of smart grid monitoring of the future. This fusion of technologies and the knowledge of two research and development teams with more than 10 years of experience will allow us to move forward and to develop new applications together.”

Investment Director Brieuc de Hults said in the statement: “As an investor, Korys always fully supports its portfolio companies and helps them to grow and develop as best they can. A new acquisition is a logical step for this type of growth strategy and we are very exited about the growth opportunities this transaction offers.”
