Bear Power Solutions supplies new Type II mineral transformer oil in sealed 55-gallon steel drums for utilities, electrical contractors, transformer service shops, OEMs, and industrial end users. This high-grade naphthenic insulating oil is manufactured to ASTM D3487 specifications and engineered for dielectric strength, thermal stability, and extended service life in liquid-filled transformers, switchgear, reclosers, regulators, and capacitor banks.
The 55-gallon drum is the right size for top-offs, single-unit fills, mobile service trucks, and field repairs where a 275-gallon tote is more product than the job calls for. Each drum ships sealed with a fresh product certificate of analysis — no reclaimed or reprocessed oil, no PCBs. Drums are standard 22.5″ diameter and palletize four to a 48×48 pallet for efficient freight.
