UTEC identified the need to increase the life expectancy of transformer insulation systems and minimise the effects of elevated hotspot temperatures from inverter-generated harmonics. By incorporating INSULutions® DPE into their designs, UTEC ensures industry-proven reliability and enhanced thermal rating, reducing the risk of transformer damage.

Technical benefits of INSULutions® DPE include thermal class of 130°C in mineral oil systems and 140°C in ester liquid systems, longer life and greater resilience to overload operation compared to traditional papers, and the ability to design more compact transformers.

UTEC’s use of INSULutions® DPE has increased the reliability of transformers for various applications, including renewable energy generation, by offering compatibility with different fluids and increased resilience to overvoltage conditions.

INSULutions® DPE is a cellulose-based insulation paper technology engineered to exceed the performance of traditional papers, providing UTEC with a reliable solution for improved transformer performance and lifespan in renewable energy applications.
