3M™ Aluminum Conductor Composite Reinforced Customer Installations - Extra High Voltage and Renewable Energy

  • Amprion GmbH, Lingen, Germany – Hannekenfahr-Gersteinwerk, 400 kV line

    To prepare for expected load growth due to the expansion of renewables in the area, Amprion installed 3M ACCR 470 kcmil (238 mm²) on a 400 kV line. Amprion has the largest EHV transmission system in Germany, which runs between Lower Saxony and the border to Switzerland and Austria. Amprion chose the conductor only after it passed a dozen tests, including strength and installation testing.

  • Réseau de Transport d’Electricité (RTE), Distré, France – Avoine - Distré, 400 kV bundled

    RTE, a wholly-owned subsidiary of EdF, is the transmission system operator of France. After intensive testing, including corona, strength, short circuit, resistance and thermal-mechanical testing, RTE installed 3M ACCR 1033 TW T-28 in close quarters near the Distré substation. The 400 kV line had become thermally limited and more capacity was needed for anticipated renewable energy sources.
