As electricity grids expand and renewable energy integration increases, transformer manufacturers face growing expectations regarding performance, durability, environmental responsibility and regulatory compliance. Coating technologies play a crucial role in meeting these requirements. From the transformer core to external surfaces, modern coating systems contribute to electrical efficiency, corrosion protection, operational reliability and long-term asset performance.
KANSAI HELIOS supports transformer manufacturers with specialized coating solutions designed to protect transformers throughout their entire service life. Our portfolio combines advanced core plate varnishes with high-performance internal and external protective coating systems tailored specifically to transformer applications.
Regulatory Developments driving the Transition to chromium-free Solutions
One of the most significant developments currently shaping the transformer industry is the transition toward chromium-free technologies for grain-oriented electrical steel (GOES). Regulatory developments and increasing sustainability and environmental requirements are driving interest in alternatives to traditional chromium-containing coatings. The move towards chromium-free solutions is no longer a future topic. It is becoming an increasingly important consideration for steel producers and transformer manufacturers worldwide.
Chromium-Free GO Core Plate Varnish Technology
As a global market leader in core plate varnishes, KANSAI HELIOS has been driving innovation in this field for decades. Our chromium-free coating solutions for grain-oriented electrical steel provide excellent insulating properties, reliable processability and long-term performance while supporting the industry’s sustainability goals. Developed through extensive research and close cooperation with customers, these solutions help manufacturers prepare for future requirements without compromising efficiency or product quality.
External transformer components are continuously exposed to moisture, UV radiation, chemicals and corrosive environments, while internal surfaces must withstand contact with transformer oils, natural esters, synthetic esters and elevated operating temperatures. To address these challenges, KANSAI HELIOS offers coating systems for internal and external transformer protection, including waterborne, high-solid and solvent-based technologies developed for demanding industrial environments.
By combining expertise in core plate varnishes, chromium-free GO coatings and protective coating systems, KANSAI HELIOS delivers a unique portfolio that supports transformer manufacturers from the core to the outer surface. Our technical specialists work closely with customers to develop customized solutions that improve performance, support sustainability objectives and extend service life.
