ARALDITE® Insulation Epoxy Successfully Applied in The World’s Largest Dry-Type Power Transformer
SHANGHAI, China, May 30, 2023 -- Advanced Materials experts from Huntsman (NYSE: HUN) have collaborated with TBEA Group, a global leading enterprise in manufacturing of power transmission and distribution equipment with an annual transformer output of 260 million kVA, ranking first in the world, on an outdoor dry-type transformer (DDT), which has the world's largest capacity and the highest voltage. It has just passed the final trial and was officially put into service at the end of April.
The size of the dry-type power transformer is about 9.6 meters in length, 6.3 meters in width and 5 meters in height. Its total weight is more than 160 tons. Most importantly, it has a capacity of 50,000 kVA and a voltage class of 115:36.5, which is the highest in the world’s electrical industry.
Due to the large size and high voltage, the project demanded higher requirements for performance. ARALDITE® insulation epoxies were up to the challenge, delivering anti-cracking, electrical insulation, and thermal conductivity properties for the record-breaking DDT.
“ARALDITE® insulation epoxy plays a key role in this project, especially in the insulation material’s post-curing and demold process, which solved the easy-to-crack problem brought on by the transformer’s large size,” said TBEA Group Chief Technical Head Jie Meng.
This success allows for more options for power transmission and distribution in high voltage areas. Jason Song, senior sales manager for power applications in Huntsman’s Advanced Materials division said, “Before the successful trial of the 50000kVA/110kV dry-type power transformer, oil type transformers were typically used in high voltage areas. However, oil type transformers can be subject to environmental concerns with their flammability and potential leaks. Dry-type transformers are not prone to those same risks.”
Jordan Wu, technical service manager of power applications for Huntsman’s Advanced Materials division added, “The successful application of ARALDITE® insulation epoxy in the world’s largest capacity and the highest voltage dry-type power transformer is a milestone in the electrical industry. We hope to see additional development and utilization of large capacity, high voltage dry-type transformers in the future.”
