ABB has launched a new longer-life distribution transformer called TXtreme, featuring a special coating that protects the transformer from corrosion in the most severe environments.

Roughly 80% of distribution transformers fail due to rust, corrosion, or leaks. ABB’s TXtreme aims to mitigate failures and increase grid resilience.

Distribution transformers are key assets in power transmission and distribution networks, and are currently designed to operate 20 to 30 years. However, harsh operating conditions containing salt, moisture, or chemicals can cause premature corrosion, which is one of the main causes of transformer leaks or failure.

The need of utilities and grid operators to protect energy supply with exceptionally robust electrical equipment is greater than ever, to ensure asset resilience and grid reliability. Equipment uptime and continuous energy supply are also critical to industries, such as the oil and gas sector.

An offshore platform can be a damaging environment for a transformer, due to its continuous exposure to wind and salt water. This may lead to premature transformer failure and force operators to replace units prematurely or develop costly alternatives using stainless steel materials.

To mitigate these issues, ABB has mastered the process of applying a unique coating formula that ensures ongoing operation of the distribution transformer. ABB’s new innovation significantly protects the transformer from corrosive substances, extending its service life and eliminating the cost of frequent repainting. 

“We are delighted to provide this innovative product to support increased grid resilience and reliability for utilities, and optimized performance and improved uptime for industries,” said Markus Heimbach, Managing Director of ABB’s Transformers business unit, a part of the company’s Power Grids division. “TXtreme is an integral part of ABB’s Transformer Resilience initiative designed to help utilities protect assets and is another example of our Next Level strategy to enable a stronger, smarter and greener grid.”

ABB offers a complete range of power and distribution transformers designed for reliability, durability and efficiency. The company’s vast portfolio includes both liquid-filled and dry-type transformers as well as services for complete lifecycle support, including replacement parts and components.
