Transformer oil

Transformer oil is a highly refined mineral oil renowned for its high-temperature stability and exceptional electrical insulating properties. It is primarily used in oil-filled transformers, various types of high-voltage capacitors, fluorescent lamp ballasts, certain high-voltage switches, and circuit breakers. This oil is critical in insulating electrical components and serving as a coolant to maintain optimal temperature. 

Petrotek provides premium-grade transformer oils in the UAE, including Bahrain, Kuwait, Qatar, Saudi Arabia, and the UAE. We ensure businesses in Fujairah, Ras Al Khaimah, Sharjah, Abu Dhabi, and beyond receive top-tier products that improve equipment longevity and performance under demanding conditions.

Petrotek offers specialized types of Transformer Oils designed to meet the demands of electrical equipment operating under different environmental and load conditions.

1. Uninhibited Transformer Oils

Uninhibited Transformer oil is a high-performance uninhibited transformer oil formulated for use in oil-filled transformers and high-voltage electrical equipment. Known for its excellent oxidation resistance and thermal stability, this electrical insulating oil is engineered to deliver superior performance even in demanding industrial conditions.

With its low-viscosity formulation, promotes optimal circulation and rapid heat dissipation, making it an ideal solution for environments requiring efficient cooling and prolonged transformer life. Petrotek, as a leading transformer oil supplier, ensures that businesses in a wide range of sectors receive reliable and long-lasting oil solutions.

2. Inhibited Transformer Oils

Inhibited Transformer Oil is a high-grade inhibited transformer oil, specially formulated with oxidation inhibitors to provide enhanced long-term stability and performance. This high quality transformer oil is suitable for application in transformers and oil-filled electrical switches and initial resistors. 

As part of Petrotek’s reliable line of industrial lubricants, Transformer Oils are designed to meet the insulation and cooling demands of modern high-voltage electrical systems.
