PUMA TRANSFORMER OIL Transformer Fluid - Uninhibited Puma Transformer Oil is product specially developed for use in oil-filled electrical equipment – including power and distribution transformers, rectifiers, circuit breakers and switchgears.
Designed to Perform
Puma Transformer Oil fulfils the requirements for NRS 079-1:2004 uninhibited oil. This product is classified as a high grade. Puma Transformer Oil is rigorously analysed and passes the following corrosion tests:
ASTM D1275 method B
IEC 62535
DIN 51353
PCB: not detectable according to IEC 61619:1997
DBDS: not detectable according to method using GC-AED
Performance Characteristics Due to its low viscosity and viscosity index, Puma Transformer Oil has extremely good heat transfer characteristics; ensuring heat is efficiently removed from the transformer core and windings.
Developed and formulated to deliver superb resistance to oil degradation, this grade provides excellent oxidation stability for enhanced transformer life and minimum maintenance. Naphthenic characteristics of Puma Transformer Oil, allows the transformer to start at the lowest possible temperature – without using pour point depressants. This insulating oil meets and exceeds the toughest demands on dielectric strength when stored and handled correctly.
