PRODUCT DESCRIPTION
PEAK ELECTRICAL INSULATING OIL is an inhibited high-grade electrical insulating oil, which
conforms to IEC 60296 Edition 4.0. It has been specially developed for use in oil-filled
electrical equipment including power and distribution transformers, circuit breakers,
rectifiers and switchgear.
BENEFITS
-
- Strong resistance to oil degradation
- Excellent oxidation stability for a longer transformer life with less maintenance
- Superior low temperature properties without the use of pour point depressants
- High dielectric strength which exceeds the toughest requirements without experiencing
failure of its insulating properties - Excellent heat transfer due to its low viscosity and viscosity index, ensuring heat is efficiently removed from core and windings
