美孚Univolt N 61 B 
UNIVOLT™ N 61 B
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
Applications
- Oil filled electrical equipment such as transformers, load tap chargers, 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
