AmpaCity can replace up to five conventional 10,000-volt cables. In addition, fewer transformer substations are required, because superconductors can transmit even large electricity volumes at a lower voltage. In this way valuable spaces in the city are freed up for other uses.
With the project launch of AmpaCity in 2011 the superconductor has become part of the research project on intelligent electricity distribution in the city. After type verification and testing in Nexans’ high-voltage test lab were completed, manufacturing of the cable commenced. Ground-breaking and underground engineering followed and the cable was laid. Since the superconductor was officially commissioned on 30 April 2014, it has been integrated into day-to-day grid operation and the testing phase continues.
