Electrical Insulating Oil

Product Description

Univolt™ N 61B is a good quality, fully inhibited transformer oil designed to meet the operating requirements of transformers and other oil filled electrical equipment. It meets the requirements of ASTM D 3487 Type II fluid, providing good performance in transformers, circuit breakers, switches, and capacitors.


Features and Benefits

Univolt N 61B is manufactured from carefully selected base stocks favored by the domestic power industry under stringently controlled manufacturing conditions. It meets the demanding requirements of the ANSI/ASTM D 3487 specification for electrical insulating oils.

•  Good Oxidation stability helps to extend lubricant service life and reduce maintenance costs

•  Great low temperature performance helps enable easy low temperature start up

•  Industry proven insulating properties



     •  Oil filled electrical equipment such as transformers, load tap chagers, switches, circuit breakers, high voltage capacitors, and lamp ballasts

     •  Some EDM (electrical discharge machines) as a coolant and insulator between charged electrodes

     •  Applications where a low viscosity mineral oil providing good low temperature properties is required
