Outdoor systems for a more resilient grid

Power distribution grids are becoming more and more complex. To facilitate a reliable power supply, increased resilience is needed. Therefore, we focus on helping customers to improve the reliability and efficiency of their distribution grids. From the substation to the end users, we offer a complete portfolio for energy distribution over the entire supply chain: from planning through design and manufacturing up to installation, operation and service. By keeping them a step ahead of their challenges from end to end, utilities are enabled to optimize less developed network environments towards a future-oriented smarter grid.
