Univolt N 61 B

Electrical Insulating Oil

安全数据表 (MSDS) 产品数据表 (PDS)

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 costsGreat low temperature performance helps enable easy low temperature start upIndustry proven insulating properties

ApplicationsOil filled electrical equipment such as transformers, load tap chargers, switches, circuit breakers, high voltage capacitors, and lamp ballastsSome EDM (electrical discharge machines) as a coolant and insulator between charged electrodesApplications where a low viscosity mineral oil providing good low temperature properties is required Specifications and Approvals

Univolt N 61 B meets or exceed the requirements of:
ASTM D 3487 Type II (2000)
