Tougher than any challenge
Special transformers for industrial applications

Answers for energy.

Familiar with the most demanding tasks
The comprehensive Siemens range of robust, reliable, and highly cost-effective transformers for industrial applications

Transformers play an eminently important role in several industries, especially in metallurgical plants and processes. Enormouscurrents need to be supplied for AC and DC electric arc furnaces and ladle furnaces in the primary aluminum, copper, zinc, chlorine, and carbon industries, or for large industrial drives. And while production capacities are growing on a grand scale in order to satisfy worldwide demand, higher voltages and currents need to be supplied by more and more powerful transformers. The working conditions fortransformers that supply the energy for such processes are usually extraordinarily severe. The transformers, exposed to cyclic load and high thermal stress, must withstand frequent overcurrents and overvoltages caused by short circuits in the furnace or the tripping of high-voltage circuit breakers. On the other hand, any outage can cause a total loss of production due to the “freezing” of pots orfurnaces. That is why off-the-shelf solutions will never do for heavy-duty industrial processes. Each single transformer needs to be precisely tailored to meet individual demands. Siemens transformers for industrial applications have led this field for more than five decades – thanks to over 100 years of experience in transformer technology and Siemens’ unique expertise throughout the entireenergy conversion chain.

Siemens transformers for industrial applications are widely renowned for superior design and innovative engineering, low fault rates, and outstanding durability. And Siemens’ close global network of experts and production facilities, as well as the company’s strong commitment to problem solving, make sure that all requirements are met with technical excellence, even withintight time frames. That is why Siemens transformers come with a unique five-year warranty. Siemens also supplies the special medium-voltage transformers required for the renowned Perfect Harmony drives – versatile performers that help significantly increase productivity and provide the highest levels of reliability, precision, and longevity in demanding industrial applications. Be it in metallurgy,mining, water supply and distribution, pulp and paper, cement production, or marine applications – even for oil and gas production 2,000 meters under the sea: Siemens transformers for industrial applications come into play whenever extraordinarily tough challenges are to be successfully met. Discover the comprehensive range of Siemens oilimmersed and dry-type transformers for industrialapplications. See for yourself the benefits Siemens transformers have to offer when it comes to the reliable supply of power for industrial core processes.
