What technical properties are listed in a Nynas transformer oil data sheet?

A transformer oil data sheet commonly lists viscosity, density, pour point, flash point, BDV, dielectric dissipation factor, resistivity, acidity, interfacial tension, moisture content limits, oxidation stability, and corrosion or sulfur behavior requirements. It may also declare compliance with standards like IEC 60296 or ASTM D3487 and specify whether the oil is inhibited. The goal is to show that the oil meets dielectric and thermal performance targets for power equipment use.
