Oil & Gas

Oil and gas platforms need transformers to supply electricity to their vital operating systems. MIDEL 7131 has a long history in these environments because it delivers a critical solution for fire safety, reliability and environmental protection requirements.

A transformer fire on a platform is likely to have disastrous and costly consequences. Choosing MIDEL 7131 in place of mineral oil increases fire safety because it has a much higher fire point (>300°C) and a 100% fire safety record. Specifying MIDEL 7131 may allow for a smaller fire suppression system, thereby reducing the cost and size of the platform.

In offshore applications performance is just as important as fire safety. If a transformer failed to withstand the corrosive conditions it would need to undergo expensive, unplanned maintenance. MIDEL 7131 reduces the likelihood of breakdown because it is extremely robust and has good oxygen stability.

Transformers located on oil and gas platforms should also be designed to have minimal impact on the environment. In this respect mineral oil cannot compare to the readily biodegradable and non-water hazardous properties of MIDEL 7131.
