Servo Electra Plus is a transformer oil or so called un-inhibited insulation oil used in transformers and circuit breakers. This oil is made through refining of optimum type of hydrocarbons, thus giving extra longer service life. This oil does not contain Poly-Chlorinated Biphenyis. Servo Electra Plus can be used in small stabilizers such as servo, manual and automatic and can also be used in HT Transformers or distribution transformers.
