Forecasts predict that there will be 27 megacities with over ten million inhabitants by 2020. Energy requirements will continue to rise in the world’s major hubs while the amount space available for substations will shrink.
The trend towards increasingly compact substations and the dynamic changes to energy infrastructures place new demands on power transformers. They are expected to provide maximum flexibility along with optimum safety and efficiency for a service life of at least 40 years.
The new Oerlikon substation is a shining example for space-saving construction. Located right in the center of a Zurich neighborhood, the system is spread across three underground levels, directly below an ewz network base. Together, the two structures take up just 30 percent of the space needed for older outdoor switching stations.
The PFISTERER Group,, has secured a leading position on the global market for high voltage insulators with the acquisition of all the shares in LAPP Insulators Holding, based in Wunsiedel, Germany from Quadriga Capital.
The mobile hybrid CrossPower energy management system is the first system that allows users to set up decentralized, robust, and scalable power grids using renewable energy anywhere in the world. The intelligent control system allows all types of available energy sources to be mixed and finds the ideal balance between energy generation and consumption.
The dry, plug-in CONNEX connection system has recently been deemed suitable for use with extra-high voltages of up to 550 kV. The universal cable system, which can withstand even the harshest weather conditions, is the only system to be certified for off-shore use.
In the latest two-wing prototypes in Husumer wind test field in the North Sea’s largest wind farm, Global Tech I, and in almost every high-speed train in Europe, the PLUG connection system by PFISTERER guarantees the secure transmission of power.
The growing trend for building off-shore wind farms across larger expanses of space, using more powerful turbines, and designing an increasing number of ring-type connection system has resulted in an increase to the amount of power that needs to be transmitted between the turbines and the substation.
