We are pleased to continue our partnership with Energinet as we endeavor to connect Sweden and Denmark once again through high-voltage cables. This collaboration reaffirms the trust of our customers in our advanced cable solutions and our commitment to fostering efficient and sustainable energy connectivity between nations.”
