New: Solutions for high-temperature transformers

MR demonstrates innovation leadership once again

Our cities keep getting bigger with more and more people living in metropolises. An increasing amount of infrastructure is needed and the power supply requirements are constantly growing. At the same time, however, the space available for new transformers is getting smaller and smaller. Wouldn't it be fantastic if you could simply operate the available transformers in the overload range temporarily during peak loads?

But operating transformers in the overload range causes the oil temperatures to rise. Transformers and accessories are not designed for that. Until now. Maschinenfabrik Reinhausen (MR) is providing solutions that turn your transformer into a high-temperature transformer. The key is ester in combination with high-temperature insulating materials for transformers, tap changers and accessories.

As an alternative insulating liquid, ester offers many known advantages to mineral oil. The high combustion point of ester means it does not easily catch fire – a crucial advantage when it comes to fire safety. Ester liquids also meet high environmental standards, because they are biodegradable and non-toxic. These advantages reduce the operating risks enormously.

Furthermore, ester allows for high operating temperatures. Using high-temperature insulating materials for a transformer, and tap changer as well, lets you raise transformers to a whole new level with alternative insulating liquids. Your transformer becomes a high-temperature transformer.

High-temperature transformers enable increased grid flexibility, availability, stability and system safety through
- reduced size or increased power for a transformer in the smallest of spaces
- lower weight and a more compact design for mobile units
- the highest possible overload capacity for load peaks or emergencies

The world's first high-temperature on-load tap-changers and de-energized tap-changers from Maschinenfabrik Reinhausen (MR) let you benefit from all of these advantages. We offer tap changer sets that are suitable above the IEC standard temperatures. Transformers with our proven products can be operated at 130 °C or even up to 150 °C.
