KEY-147 High Purity Vegetable Insulating Oil

Features Of KEY-147 High Purity Vegetable Insulating Oil

1. Naturally derived from non-GMO, high-oleic sunflower seed oil with >99.5% purity by GC-FID analysis.

2. Exceptional dielectric strength (>60 kV per ASTM D877) and low ionic impurity content (<1 µS/cm conductivity).

3. Biodegradable (OECD 301F >85% in 28 days) and non-toxic to aquatic life (EC50 >100 mg/L, Daphnia magna).

4. High flash point (>320 °C, ASTM D92) and excellent thermal oxidative stability (RPVOT >1,200 min at 110 °C).

5. Sulfur-free, chlorine-free, and metal-free formulation—meets IEC 62770:2022 requirements for natural ester insulating fluids.

Typical Applications Of KEY-147 High Purity Vegetable Insulating Oil

1. Dielectric fluid in distribution and power transformers (up to 345 kV), especially in environmentally sensitive or indoor locations.

2. Insulating and cooling medium in dry-type and liquid-immersed cast-resin transformers.

3. Base fluid for formulated biodegradable transformer oils meeting IEEE C57.147 and IEC 62770 standards.

4. Replacement for mineral oil in retrofill applications where enhanced fire safety and sustainability are prioritized.

5. Component in specialty lubricants for high-voltage switchgear and reclosers requiring low environmental impact.

KEY-147 High Purity Vegetable Insulating Oil – Frequently Asked Questions (FAQ)

Q1: What is the CAS Registry Number for KEY-147?

A: The CAS Number for KEY-147 High Purity Vegetable Insulating Oil is 8001-21-6 (refers to refined high-oleic sunflower oil as defined under IEC 62770 Annex A).

Q2: Can KEY-147 be used directly as a drop-in replacement for mineral oil without equipment modification?

A: Not without assessment—KEY-147 is retrofill-compatible but requires verification of seal integrity, moisture content (<30 ppm), and dissolved gas analysis (DGA) baseline per IEEE C57.155. System drying and filtration are strongly recommended prior to filling.

Q3: How does KEY-147 compare to synthetic esters (e.g., TMP triheptanoate) in terms of oxidation resistance and cost?

A: KEY-147 offers comparable oxidation stability to mid-tier synthetic esters (RPVOT >1,200 min) at ~40% lower material cost. It exhibits higher natural hydrolytic stability than many synthetics but slightly lower viscosity index (VI ≈ 185 vs. >200 for synthetics).

Q4: Does KEY-147 support migration of additives such as antioxidants or metal passivators?

A: Yes—KEY-147’s polar triglyceride structure enables effective solubilization and dispersion of common phenolic antioxidants (e.g., BHT) and benzotriazole-based copper passivators without phase separation or precipitation under operating temperatures.

Q5: Is KEY-147 certified under UL Environment or EPAct 2005 bio-based content standards?

A: Yes—KEY-147 is USDA BioPreferred® certified (100% bio-based content by ASTM D6866) and carries UL Environment ECVP validation for biodegradability and aquatic toxicity compliance.
