Transformer oil is used to cool and insulate electrical transformers, made from highly refined mineral oil. It is important to use the correct grade for indoor or outdoor use and to add it correctly to prevent malfunctions. Professionals should be hired for this task.
The devices used to alter the electrical flow are known as transformers and can be used for a variety of operations. These units need to be cooled and insulated, so transformer oil can be added to do this. This product is made from a highly refined mineral oil to remove impurities. It is usually sold in very large containers and added by a person with experience in industrial maintenance.
Transformer oil is made from mineral oil, which means it is originally derived from petroleum. After being extracted, this oil is refined to produce a clear, colorless liquid, and the finished product is also usually odorless. While it may resemble mineral oil used for household applications, this product is actually much purer and contains little to no impurities. This means that ordinary mineral oil should not be replaced with this type of lubricant.
There are many other uses for transformer oil, including lamp ballasts, capacitors, circuit breakers, and high-power switches. These devices can be placed indoors or out, so this insulating oil can be rated for indoor or outdoor use. It is important not to use grade oil in outdoor products or grade oil in those placed indoors because each unit may have different cooling and lubrication needs.
A flame retardant chemical may be added to transformer oil, especially when the product is used indoors. This can help prevent the insulating oil from catching fire if the transformer gets too hot. Some types of silicone can be added to interior oil and this tends to keep the flame retardant chemical stable.
Transformer oil normally comes in large containers ranging from two to five gallons (7.57 to 18.93 l) dry. One of these enclosures is ideal for businesses that need to maintain only a few transformers or circuit breakers. Large industrial facilities may need to add this insulating oil to several hundred high voltage transformers or capacitors, in which case it may be best to purchase this product in 55 gallon (208.2 L) drums.
It is recommended that this mineral oil be added by a professional who has been trained how to do it correctly. This is because adding transformer oil in the wrong place or in too much could cause high voltage capacitors or circuit breakers to malfunction. As a result, many industries hire mechanics who specialize in machining transformers and other electrical equipment to protect these very expensive assets.
