Dow Corning® 561 Silicone Transformer Fluid is an ideal safety fluid for use in oil filled transformers and be used safely even when the transformer must be located close to the load, indoors or near buildings.

561 Transformer Fluid contains no chlorine or other halogens. It is pure polydimethylsiloxane material that contains no additives. It is compatible with materials used in the construction of transformers, non-volatile, thermally stable and chemically inert. This helps to prolong the life of the transformer and helps reduce maintenance.

561 Transformer fluid has been tested and approved by authorities around the world for use in electrical applications. Due to its high fire point it is extremely difficult to ignite but, if it should burn, its emissions are extremely low, and it is self-extinguishing.
