DuPont has introduced its trademarked ReliatraN SIDT, the first underground residential solid insulation distribution transformer that uses patented oil-free technology to provide a more sustainable solution for utility companies, developers and home owners. The product now is available in North America.
The new oil-free single-phase submersible transformer is about 50 per cent smaller than conventional oil-filled versions. The smaller size and oil-free construction help to reduce the risk of contamination. The ReliatraN SIDT also alleviates concerns about exposure to mineral oil. In contrast, oil-filled units carry a risk of leaks.
The new product uses patented oil-free technology and DuPont Nomex brand insulation.
“We are focused on innovations that provide sustainable solutions for our customers,” said William F Weber, vice president for North America - DuPont protection technologies. “The critical materials used in oil-filled transformers have not changed substantially since these transformers were introduced in the late 19th century. Industry executives have told us they are looking to material science and companies like DuPont to bring change to the industry, and we want to be a materials leader in this market.”
Safety advantages
The ReliatraN SIDT offers important safety advantages. The transformer’s construction is fire-resistant and self-extinguishing. Inside, the product’s brand paper is the most critical insulating component. It does not support combustion in air; provides high levels of electrical, chemical and mechanical integrity; and is widely recognised for extending transformer life.
Environmental concerns due to the risk of oil leakage have kept many utilities from offering an underground choice to residential developers, even though industry research shows that homeowners prefer transformers be out of sight. ReliatraN SIDT addresses concerns of utility companies while providing a low-maintenance, reliable single-phase submersible transformer.
DuPont operates in more than 70 countries.
