Specialized polymer concrete composite material for in-situ cleansing/improvement of transformer oil

By the very nature of its composition, involving the presence of micron-size particles bridging the various aggregate fractions in the matrix, a very large specific surface becomes available for adsorptive mechanisms to come into play. The diffusion of fluids through the polymeric films on the filler materials in polymer concrete, coupled with the adsorptive nature of the matrix, together offer a beneficial opportunity of interest to the transformer industry. Specifically, this opportunity pertains to the in-situ cleansing/improving of transformer oil during the operational life of the transformer. The premise of this paper is that the purification ability of polymer concrete in an oil-filled transformer environment can render many economic benefits in both a specific and overall sense by reducing or eliminating oil-related maintenance chores
