As part of the energy transition, energy produced in wind, solar, or hydroelectric power generation plants often needs to be transported from remote regions to urban areas. To do this, ever more efficient and capable cables are being laid on the sea bed or buried underground. To ensure the quality of the cables in the factory and of the cable systems installed on-site, HIGHVOLT has developed a modular solution that ensures this quickly, simply, and with minimum effort and expense. The solution can be used both in the factory or on-site. Thanks to this modular solution, the test system can also be flexibly adapted to the particular challenges of any given situation.
