On August 9, the 220kV natural ester insulating oil transformer developed by CHINT successfully passed the full tests under the witness of engineers from KEMA Netherlands, an international authoritative third-party electrical equipment testing institution. The withstand voltage of lightning impulse on the high-voltage side of the transformer is up to 1050kV, 10% higher than the national standard of China 950kV.

 

This is a breakthrough after CHINT completed the 132kV natural ester insulating oil transformer in 2018, and took the lead in completing the R&D and test of 220kV natural ester insulating oil transformer in China.

 

Environmental friendly transformer represented by natural ester insulating oil transformer and high short-circuit resistance transformer are two "unique weapons" of CHINT transformer products. Since 2016, CHINT has successively produced dozens of natural ester insulating oil transformers of various voltage grades from 10kV, 13.8kV, 33kV to 132kV for users all over the world, with the cumulative contract amount of nearly 10 million dollars.

 

In April 2018, CHINT’s 132kV natural ester insulating oil transformer smoothly passed KEMA's test and was highly recognized by Australian users. In May 2019, combined natural ester insulating oil transformer developed by CHINT successfully obtained the UL certification of the Unite Sates, refreshing records of the domestic transformer manufacturer and opening the North America and the Middle East Asia market.
