Siemens Energy transformers are leveraged in very different environments, from mining to oil and gas extraction, from steel plants to chemical industries. Each area of application requires specific transformer designs to supply the right kind of power for very specific projects in very specific environments. Their especially rugged designs withstand exposure to dirt, gases, short circuit forces, and high magnetic fields. Our transformers, built for industrial applications, deliver extended voltage regulation ranges. They can provide extremely high currents and have the capacity to feed multi-pulse rectifier units to ensure low system perturbation. This allows them to withstand cyclic load and high thermal stress while remaining highly reliable. In addition, furnace transformers withstand frequent overcurrent and overvoltage caused by short circuits in the furnace or by tripped high-voltage circuit breakers.
