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.
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.
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.
Why Siemens Transformers
As a leading supplier for over six decades, Siemens not only brings more than 100 years of experience in transformer technology to its industrial transformers but a production and service network that spans the planet. This global network keeps response times short, ensures just-in-time delivery, and gives you the same extensive know-how and the same technology and quality wherever you are.
Siemens Transformers translates individual customer requirements into unique premium-quality transformers with a reputation for superior reliability and an impressive service life. Siemens has developed a wide range of design options to ensure its tailor-made transformers cover all customer use cases.
Design options for high-current transformers for industrial applications
Specifications for voltage, power rating, ambient climate, network topography, and noise level are typical transformer criteria.
Further design options include:
Within its Global Technology Center, Siemens has dedicated two Centers of Competence exclusively to driving innovation in large and medium power transformer. As a result, Siemens transformers across the board benefit from design breakthroughs, even those originally achieved for other – sometimes more complex – transformer types. This ensures cutting-edge technology across the entire transformer portfolio.
What makes Siemens transformers stand out in the market is the superior performance density they bring to especially compact and lightweight designs.
The impact of transformer outages on the process industries in which they are used can be severe because outage costs may not be limited to the cost of transformer repairs. In industrial applications, an outage may result in standstills and a total loss of production. Related costs can quickly rise to a level that affects even larger organizations. An effective way to minimize this risk is the continuous monitoring of key parameters during transformer operation. According to an independent study, online monitoring systems can detect 60% of all typical transformer errors before they occur.
The 5 top benefits of the Siemens TDCM sensor
The Siemens online monitoring system for transformers incorporates the most advanced analytical technologies. It helps to effectively reduce failure risks while increasing the efficiency of maintenance during operation.
When a transformer reaches the end of its lifecycle, it needs to be replaced to maintain the operation. Although there are ways to fast-track replacements, ordering, designing, building and even delivering a replacement transformer generally requires careful planning well ahead of its installation. Siemens experts work closely with customers to reliably remanufacture transformer originals. Customer can choose a 1:1 replica or opt for a new transformer that fits into the existing vault or chamber but offers greater capacity.
Same dimensions, higher power density
In steelworks especially, the notoriously small transformer chambers set challenging limits for capacity expansion. Thanks to extensive expertise in cooling designs and in handling high magnetic fields, Siemens is able to offer higher power density with much smaller real estate requirements than the competition.
The factory acceptance test, which Siemens transformers undergo fully assembled in Siemens own test bays, includes tests against standards specified by the customer.
These standards include but are not limited to:
Siemens designs and builds a wide range of tailor-made high-current electric arc furnaces, rectifiers, and converter transformers for applications in process industries where power is a key resource.
