SIEMENS HIGH CURRENT INDUSTRIAL TRANSFORMERS

With their reliability, low losses, and maintenance-friendly designs, Siemens High Current Industrial Transformers sets standards in cost efficiency.

Tailor-made and designed to withstand the harshest conditions, Siemens transformers provide power for industrial applications, in which current itself is a major resource – from steel manufacturing to electrolysis, from mining to offshore oil and gas platforms. Reliability and cost effectiveness are the main requirements to modern converter transformers. Find out in our exclusive whitepaper how you can specify your converter transformers to enhance your system stability while saving costs at the same time. If you operate furnace transformers you might be interested in learning what measures can be taken to further increase the reliability and lifetime of your transformers. Please find our whitepaper below.

Top performance meets superior environmental and safety standards

Furnace transformers as well as heavy-duty rectifier and converter transformers connect processes to the power grid. Their purpose is to supply a critical resource to energy-intensive industrial applications – high currents with very specific voltages. These transformers must meet rigorous requirements. Siemens ‘ expertise in design and precision manufacturing ensures customers enjoy top performance and efficiency in terms of both cost and energy. At the same time, units need to be extremely reliable in operation and environmentally sound while affording the highest level of safety for those working in their vicinity.

Heavy-duty powerhouses that withstand harshest ambient conditions

Siemens 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. Siemens transformers for all industrial environments. Their especially rugged designs withstand exposure to dirt, gases, short circuit forces, and high magnetic fields.

Siemens 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.

HIGH CURRENT INDUSTRIAL TRANSFORMERS FURNACES: ENORMOUS CURRENTS IN HARSH AMBIENT CONDITIONS

These conditions require exceptionally robust and reliable transformers to ensure they work cost-efficiently in a harsh ambience. Siemens electric arc furnaces (EAF) are built to operate under very harsh conditions, such as steel furnaces. Available for DC and AC furnaces, they provide high currents of up to 180kA for the electric arc.

ELETROLYSIS AND SMELTERING: COST EFFICIENCY AND UNINTERRUPTED POWER SUPPLY

Electrolysis processes need transformers, which supply energy with maximum reliability, to ensure stable production. Siemens rectifier transformers are used for electrical multi-pulse DC power supply to induce a chemical reaction, for example in zinc electrolysis or aluminum smelter. Available connection types include bridge and double-star design.

LARGE-DRIVE APPLICATIONS: MAXIMUM FLEXIBILITY IN VOLTAGES

Large-drive industrial applications rely on transformers, which offer flexible voltage adaption to meet the drive input voltage. These transformers are tailor-made for specific applications in harsh environments. Siemens converter transformers supply power for large-drive multi-pulse applications and variable electrical speed drives, such as blast furnaces, pump stations or rolling stock in mining applications.
