NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality chemical solutions, and our PEPE insulating oil stands as a testament to this dedication. For engineers and manufacturers focused on ensuring the optimal function of oil-immersed capacitors, understanding the detailed technical specifications of dielectric fluids is non-negotiable. This knowledge allows for informed selection and application, maximizing component performance and longevity, especially when considering capacitor dielectric fluid cold weather operational needs.

PEPE insulating oil, scientifically known as Phenyl Ethyl Phenyl Ethane, possesses a unique chemical structure that imparts superior physical and electrical properties. Let's examine some key specifications that highlight its advantage:

Appearance: The oil presents as a colorless transparent liquid, free from suspended impurities and mechanical contamination. This clarity is an indicator of its purity and the meticulous manufacturing process employed.

Density (20°C): With a density typically between 0.960-0.999 g/cm³, PEPE oil offers a specific gravity that is well-suited for capacitor applications, influencing factors like heat transfer and fluid volume stability across operating temperatures.

Dielectric Strength: This is a critical parameter for any insulating oil. PEPE oil demonstrates a robust dielectric strength, often exceeding 70 KV (using a spherical electrode). This high breakdown voltage is essential for preventing electrical arcing and ensuring the safe operation of capacitors under high electrical stress. It directly relates to the oil's ability to resist electrical breakdown, a core requirement for capacitor dielectric fluid cold weather applications where performance can be tested.

Pour Point: The pour point of PEPE insulating oil is remarkably low, typically around -60°C. This signifies its exceptional fluidity at very low temperatures, preventing the oil from solidifying and maintaining its insulating and cooling capabilities even in extreme cold. This is a cornerstone of its effectiveness in low-temperature environments, making it a prime example of phenylethyl phenyl ethane oil for capacitors.

Viscosity (40°C): A kinetic viscosity of approximately 4.0 mm²/s at 40°C indicates a relatively low viscosity that remains manageable even at low operating temperatures. This characteristic is vital for efficient heat dissipation and for ensuring the oil can readily impregnate capacitor films.

Flash Point: The high flash point, typically 140°C, indicates a low flammability risk, contributing to the overall safety profile of the dielectric fluid. This is an important consideration for any electrical application where heat generation is a factor.

When considering the purchase of such specialized materials, working with a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures that these specifications are consistently met. Understanding these technical details empowers engineers to leverage the full capabilities of PEPE insulating oil, ensuring their capacitors perform optimally, especially when dealing with the challenges presented by high performance insulating oil for cold environments.
