New TXpertTM Dry and TXpandTM Transformer Products from ABB Feature Environmentally Friendly Design

Press Release Summary:

ABB’s new TXpertTM Dry digital transformer is cooled by air and nonflammable solid insulation instead of oil, making it safer and more environmentally friendly as well as cutting down on maintenance. The dry type transformer is suitable for high risk applications including highly populated areas, offshore areas, and sensitive ecosystems, and includes smart sensors that collect data for maintenance and monitoring purposes. ABB’s TXpandTM offers critical components with rupture resistant design for risks from unpredictable failures.

ABB Expands Transformer Portfolio with Launch of New Products

New range of products to facilitate digitalization of grids and offer enhanced safety, efficiency and reliability

ABB today launched the world’s first dry-type (oil free) digital transformer, named the ABB AbilityTM TXpertTM Dry, and another innovative product called TXpandTM at its ABB Customer World (ACW) event in Xiamen, China.

The ABB AbilityTM TXpertTM Dry incorporates digital capability within ABB’s proven dry-type transform-ers. Transformers typically use oil for cooling and insulation but dry-type transformers are designed to work without oil, where the core and the coil are cooled by air and non-flammable solid insulation mate-rial. This makes them safer, as the flammability element of oil is eradicated, and also more environmen-tally friendly. Such transformers are ideally suited for high-risk applications like offshore as well as densely populated areas and sensitive eco-systems.

Smart sensors collect data and combine them into powerful analytics enable key functionality such as Power Quality Monitoring, Self-Supervision and Lifecycle Assessment, Due to its dry-type design, digital-ization and little or zero maintenance, this new transformer offers enhanced safety and data security, increased up-time and optimized operations.

ABB also announced the launch of its innovative TXpandTM solution for power transformers, where critical components such as the tank have a rupture-resistant design, to mitigate risks associated with unpredictable failures, offering enhanced safety and lowering environmental impact.

"As the world leader in transformers, we continue to push the technology boundaries increasing safety, reliability and efficiency “ said Laurent Favre, head of ABB’s transformers business, a part of the com-pany’s Power Grids division. “These latest portfolio additions reiterate our ongoing commitment to in-novation as we enable a stronger, smarter and greener grid.”

The new product announcements follow the successful launch of a range of digitally integrated trans-former technologies like the TXpertTM distribution transformers, the ABB AbilityTM based digitally inte-grated Power Transformer, as well as the TXploreTM service solution.
