Transformer Oil Making Plant

Abstract

Petroleum has long been used as insulating oils serving the purpose of insulating and cooling media for high-tension electric equipment. In particular, as the insulating oil was produced by using wax-free crude oil in early days of this century, it was possible to produce a product easily used in cold winter. Depending upon uses, insulating oils are divided into various kinds, including the insulating oil for circuit breakers and transformers, condenser oil for high-tension condensers and oil-filled cables and cable oil for insulating the core wire of impregnated power transmission cables. The technology introduced here is related to the insulating oil for circuit breakers and transformers.
