This article focuses on the critical properties of Phenylethyl Phenyl Ethane (PEPE) insulating oil, a high-performance dielectric fluid widely used in advanced capacitor technologies.

The effectiveness of an insulating oil in electrical applications is determined by a combination of its physical and electrical characteristics. For PEPE oil, these properties are specifically optimized for demanding roles, most notably as a capacitor insulation oil. Understanding these parameters is key to appreciating its value and superior performance.

Physical Properties:

  • Appearance: PEPE oil is typically a colorless, transparent liquid, indicating its purity and absence of particulate contamination.
  • Density: With a density between 0.960-0.990 g/cm³ at 20°C, it has a specific weight that is suitable for its applications.
  • Pour Point: A remarkably low pour point of ≤ -60°C is a standout feature. This means the oil remains fluid even at extremely low temperatures, crucial for low-temperature insulating oil for capacitors.
  • Flash Point: A flash point of ≥ 140°C ensures a good margin of safety during handling and operation, minimizing fire risks.
  • Viscosity: Its kinetic viscosity at 40°C is low (≤ 4.0 mm²/s), contributing to its good flowability, especially in colder conditions.

Electrical Properties:

  • Breakdown Voltage: A high breakdown voltage (≥ 70 KV) is essential for preventing electrical arcing and ensuring reliable insulation.
  • Dielectric Dissipation Factor: A very low dissipation factor (≤ 0.001 at 90°C) minimizes energy loss and heat generation within the capacitor.
  • Electric Volume Resistivity: High resistivity (≥ 1.0*10¹² Ω.m at 90°C) signifies excellent insulating capability.
  • Relative Permittivity: With a permittivity between 2.40-2.50 at 90°C, it offers stable dielectric behavior.

These comprehensive capacitor insulation oil properties underscore why PEPE oil is a preferred choice for manufacturers and engineers who require dependable performance, especially when seeking the best insulating oil for cold climates.
