For professionals in the electronics manufacturing sector, particularly those involved with capacitors, a thorough understanding of dielectric fluid specifications is paramount. Ningbo Inno Pharmchem Co., Ltd., a dedicated supplier of specialty chemicals, aims to demystify the technical specifications of Phenyl Xylyl Ethane (PXE) insulating oil, a cornerstone material in high-performance capacitor design. Knowing these details helps engineers select the right materials and ensures the reliability of their final products.

The primary function of PXE oil in a capacitor is to provide robust electrical insulation and efficient heat transfer. This is achieved through a combination of carefully controlled physical and chemical properties, as reflected in its technical specifications. When you are looking to purchase PXE oil, these are the critical parameters to evaluate. Our company, as a manufacturer in China, rigorously adheres to these standards.

Let's examine some of the key technical specifications: Appearance: The oil is described as a colorless or pale yellow transparent liquid, free from suspended matter or precipitation. This visual clarity is an initial indicator of purity. Density (20°C) typically ranges from 0.950 to 0.999 g/cm³. This density is important for fluid dynamics within the capacitor. Acid Number, measured in mg KOH/g, is kept very low (≤0.015), indicating minimal acidity, which is crucial for preventing corrosion of internal components.

Perhaps the most critical specifications for an insulating oil are its electrical properties. The Breakdown Voltage (KV), often tested using a spherical electrode with a 2.5mm clearance at 50Hz, is a measure of the oil's ability to withstand electrical stress. For PXE oil, this value is typically high, often exceeding 70 KV, which is vital for preventing dielectric breakdown. The Dielectric Loss Factor (tan δ at 90°C and 50Hz) is kept exceptionally low (≤0.001), signifying minimal energy loss when subjected to an electric field. Similarly, the Volume Resistivity (at 90°C) is very high (≥1×10¹² Ω.m), meaning it strongly resists the flow of electric current, further enhancing its insulating capabilities. For engineers who need to buy PXE insulating oil, understanding how these electrical properties contribute to capacitor performance is key.

Other important specifications include the Flash Point (≥140°C), a safety measure indicating the temperature at which vapors can ignite, and the Pour Point (≤-40°C), which determines the lowest temperature at which the oil can flow. The Kinetic Viscosity at 40°C (≤7.0 mm²/s) highlights its fluidity, which is important for impregnation processes. Finally, Water Content (ppm) is minimized (≤75), as moisture significantly degrades insulating properties.

Ningbo Inno Pharmchem Co., Ltd. is committed to providing PXE insulating oil that consistently meets these exacting technical specifications. As a reliable manufacturer and supplier, we ensure that our customers receive a product that enhances the performance and reliability of their capacitors. Choosing the right insulating oil based on these detailed parameters is a significant step towards achieving optimal results in electronic component manufacturing.
