    When dry-type transformers just don’t cut it.

    Liquid-filled and oil-filled transformers are commonly coupled with other incoming or outgoing equipment to lower the utility voltage. They’re used for a variety of industrial and commercial applications and can be used both indoors and outdoors. Liquid-filled transformers are three-phase transformers that are used across both commercial and industrial applications including mining, automotive, and assembly line machinery. They are built to withstand harsh conditions and heavy loads, all while maintaining structural, electrical and mechanical integrity.

    Liquid-filled and oil transformers tend to be the less expensive choice when used for outdoor applications. Also, while dry-type transformers have many advantages, they are limited by voltage rating and size. Liquid-filled transformers can handle much larger electrical loads and are available in higher voltage ratings as well.

    Mineral oil, silicone, fire-resistant hydrocarbon fluid. Take your pick.

    Liquid filled transformers can be filled with a variety of liquids with mineral oil being the most common choice for outdoor use, though oil filled transformers can be used indoors if enclosed in a vault. There are also many other environmentally friendly, industry standard-compliant liquids like R-Temp®, silicone, BIOTEMP®, and fire-resistant hydrocarbon fluid, just to name a few. All of these liquids are good options, but knowing your budget and where and how you will install your transformer will be able to better guide you in your choice of liquid.

    For example, mineral oil is durable, tends to be the least expensive, and would make for a good outdoor liquid. Fire-resistant hydrocarbon fluid (FRHF) is far less flammable than other liquids, is non-toxic and readily biodegradable, and can be safely used indoors. Not to mention it can extend the life of your transformer’s insulation. Silicone is a good option for both indoor and outdoor use, and has a low-flammability and low-toxicity rating. However there are always flammability concerns of some degree, as well as cleanup concerns, which can become costly.
