Raj Petro products are generally positioned for power and distribution transformers, switchgear, and other electrical equipment that uses insulating liquids, where oils must meet relevant specifications such as national standards or IEC aligned requirements. Typical applications include utility distribution transformers, industrial substations, and captive power systems that need reliable insulation and cooling performance under Indian grid conditions. In procurement, the more important point than brand is compliance: the oil should match the specified standard, be supported by certificates of analysis, and be on the buyer’s approved vendor list for the transformer population being serviced.
