Environmentally friendly, robust and highly efficient products for OEMs of wind turbine generators

In parallel to the worldwide increasing power demand, utilities and OEMs in the power sector strive for environmentally friendly and resource efficient power generation. Wind power applications make a major contribution to meeting these goals. While wind turbines were producing 0.5 MW of power at a height of 40 meters in 1990, today’s wind turbines produce 10 MW and beyond requiring higher voltage levels and innovative technologies. A transmission voltage of 66 kV has now become standard for offshore wind projects. One core aspect: The high voltage within the wind turbine network has a positive impact on cable losses and efficiency. This is where reliable, compact and environmentally friendly high-voltage products from Siemens Energy can make an excellent contribution. We are delivering sustainable high-voltage equipment to the global wind turbine market since decades.

Environmentally friendly, robust and highly efficient products from Siemens Energy have many benefits to offer. Despite the power level, our low maintenance products are designed especially for the tough conditions of offshore use, are lightweight and have a particularly compact structure. Siemens Energy high-voltage transmission products score high in terms of environmental compatibility, efficiency, maximized availability and robustness. They do not apply any fluorinated greenhouse gas, nor do they apply mineral oil. As a result, they save time and money, while assuring outstanding grid and application stability. All products are successfully IEC, seismic, and IEEE tested regarding common industry standards.

By supporting one of the most promising future energy sources, renewable wind power generation, we are in line with the outcome of the world energy forum report, published in 2014. In comparison to coal and gas power generation, wind power generation has significantly lower lifecycle emissions per GWh.

For decades, high-voltage products from Siemens Energy have proven the highest level of safety in operation as well as excellent electrical, mechanical, and thermal properties. Installation of our innovative step-up transformers and GIS in wind turbine generators avoids the application of climate-damaging oil and SF₆ gas and enables the highly efficient connection of the wind turbines for bringing wind home, making power generation from renewable energy sources even more eco-friendly and economical.

The new standard voltage level of 66 kV for connection of increasingly powerful offshore wind turbines reduces the amount of cable needed for connection of a wind farm and the process losses – making wind power even more cost-efficient.

As a leader in innovative and sustainable products, Siemens Energy Transmission is supporting the implementation of the United Nations Sustainable Development Goals. With biodegradable ester insulating fluids for step-up transformers, dry-type transformers and clean air insulation for gas-insulated switchgear we support the implementation of goals number 3 “good health and well-being”, 7 “Affordable and clean energy”, 8 “Decent work and economic growth”, 9 “Industry, innovation and infrastructure", 11 “Sustainable cities and communities”, 12 “Responsible Consumption and Production”, 14 “Life below water” and 15 "Living on land".
