Calumet Specialty Products Partners, L.P., a leading independent producer of specialty hydrocarbon and fuel products, announced the launch of CALTRAN 60-00 Group U, an all-new product that is the company’s first uninhibited transformer oil.

Uninhibited transformer oils are straight mineral oils which achieve their desired characteristics through the careful selection of crude oil and refining technology, whereas inhibited transformer oils are additized with antioxidants for greater chemical stability.

CALTRAN 60-00 Group U is a naphthenic-based transformer oil specifically engineered to meet the International Standard IEC 60296, ed. 4, 2012 General Specifications for uninhibited transformer oil, according to Calumet. The technology has been verified by an accredited third-party laboratory, the company added.

“Our product development team is proud to have met the current stringent International Standard. This innovative transformer oil demonstrates Calumet’s commitment to developing high-quality specialty products for our customers,” said Harji Gill, vice president of Export Sales & Business Development at Calumet Specialty Products Partners.

CALTRAN 60-00 Group U is available for shipment starting June 2017.

CALTRAN 60-00 Group U is appropriate for use in distribution and power transformers and switchgear. In addition, CALTRAN 60-00 Group U offers:
• Superior cooling properties along with the wider heat exchange properties of a naphthenic oil
• Outstanding oxidation stability under severe conditions, without the use of additives
• Fully miscible with insulating oils meeting IEC 60296:2012 and ASTM D3487 standards
• Meets IP 346 and Modified Ames Criteria for biological safety

“Customers now have a superior choice in protecting their investment. Our new transformer oil forms optimal protection for electrical equipment; combining enhanced protection against corrosion, longer oil life and greater efficiency,” he added.
