Electrical Grade Castor Oil

Overview

CanCastor's Electrical Grade Castor Oil represents a breakthrough in sustainable and high-performance dielectric fluids, meticulously engineered to meet the rigorous demands of modern electrical insulation and cooling systems. Derived from the renewable Ricinus communis plant, this specialized castor oil offers a sustainable, high-performance alternative to traditional petroleum-based dielectric fluids, aligning with the growing industry demand for greener and safer solutions. Our Electrical Grade Castor Oil (CAS: 8001-79-4, INCI: Ricinus Communis (Castor) Seed Oil) is produced through advanced refinement processes, ensuring exceptional purity, stability, and dielectric performance. Its unique molecular structure, primarily composed of the triglyceride of ricinoleic acid, imparts superior inherent properties such as high dielectric strength, excellent thermal stability, and a naturally high flash point, making it ideal for critical high-voltage applications.

Engineered to perform in demanding environments, CanCastor's Electrical Grade Castor Oil provides robust insulation and efficient heat dissipation across a wide range of operating temperatures. We understand the precise requirements of the electrical industry, from power transformers and distribution transformers to capacitors and switchgear. Our product not only adheres to but often surpasses the stringent performance criteria outlined by international standards such as ASTM D117, ASTM D3487, and IEC 60296 for insulating oils. By choosing CanCastor, our clients benefit from a proven track record of delivering consistent quality and reliability, backed by our commitment to sustainable industrial practices and rigorous batch testing protocols.

Key Physical & Chemical Properties

CanCastor’s Electrical Grade Castor Oil is characterized by its outstanding dielectric properties and robust physical profile:

• Dielectric Strength (Breakdown Voltage): >40 kV (typically 50-60 kV per 2.5mm gap, tested as per ASTM D877/IEC 60156) – Crucial for insulation integrity under high electrical stress.
• Water Content: <100 ppm (parts per million, tested as per ASTM D1533/IEC 60814) – Low moisture content is vital to prevent dielectric breakdown.
• Acid Value: <0.25 mg KOH/g (tested as per ASTM D974/IEC 66205) – Indicates excellent oxidative stability and minimal corrosive potential.
• Viscosity @ 40°C: 240-280 cSt (centistokes, tested as per ASTM D445/IEC 60404-1) – Ensures efficient heat transfer and flow characteristics for cooling.
• Pour Point: Typically -15°C to -20°C (tested as per ASTM D97/IEC 60296) – Enables reliable performance in cold climates.
• Flash Point (COC): >280°C (Cleveland Open Cup, tested as per ASTM D92/IEC 60296) – Significantly enhances fire safety compared to conventional oils.
• Specific Gravity @ 20°C: 0.958 – 0.962 (tested as per ASTM D1298/IEC 60296) – Key for design considerations in immersion applications.
• Volume Resistivity @ 90°C: >1 x 10^12 Ohm·cm (tested as per ASTM D257/IEC 60093) – Measures electrical resistance, ensuring minimal leakage current.
