High-temperature resistant liquid-filled transformers provide a robust solution for industries requiring consistent power under high-temperature conditions. These transformers are designed to operate at full load without the risk of tripping, ensuring continuous power supply. The use of high-temperature resistant liquid enhances their performance, providing superior oxidation resistance and a slower aging rate compared to conventional mineral oil. Additionally, the coils are insulated with NOMEX insulation paper, which offers stable mechanical and electrical performance under high temperatures and has a long lifespan.
The benefits of the distribution transformer
High-temperature resistant transformers are designed with sustainability in mind. The materials used can be recycled and reused at the end of the transformer's service life, aligning with environmental protection goals. NOMEX insulation paper is biodegradable, and the high temperature-resistant oil operates well below its temperature resistance level, making it recyclable after proper treatment. The treated waste can be decomposed by soil microorganisms without toxicity, preventing long-term environmental pollution.
high-temperature-resistant products are designed to handle fluctuating and unstable loads. The insulation system in these transformers remains intact under these conditions, ensuring safe and reliable long-term operation.
