Capacitors designed for high voltage applications demand materials that can withstand extreme electrical stress. NINGBO INNO PHARMCHEM CO.,LTD. offers Phenyl Xylyl Ethane (PXE) oil, a premium dielectric fluid meticulously engineered to meet these demanding requirements. Understanding the science behind its performance is key to appreciating its value in advanced electrical systems.

The primary function of a dielectric fluid in a high voltage capacitor is to provide robust electrical insulation. PXE oil, also known as phenyl xylyl ethane insulating oil, possesses a remarkably high breakdown voltage. This property is measured in kilovolts (KV) and indicates the maximum electric field strength the fluid can withstand before it begins to conduct electricity. For high voltage applications, a higher breakdown voltage is paramount to prevent electrical arcing and short circuits within the capacitor, ensuring operational safety and reliability. The technical specifications highlight a breakdown voltage of typically 70 KV or more, making it a leading choice for such systems.

Beyond breakdown voltage, other electrical properties are equally important. The dielectric dissipation factor, for instance, measures the energy lost as heat when the dielectric material is subjected to an alternating electric field. A low dissipation factor, as exhibited by PXE oil (often below 0.001 at 90°C), signifies minimal energy loss, leading to greater efficiency and less heat generation within the capacitor. Similarly, high volume resistivity indicates the fluid's resistance to direct current flow, further confirming its excellent insulating capabilities.

Furthermore, the chemical stability and compatibility of the dielectric fluid are crucial for the longevity of high voltage capacitors. PXE oil is known for its great compatibility with polypropylene film, a common material used in modern high-voltage film capacitors. This synergy ensures that the materials work harmoniously, preventing degradation and maintaining performance over extended periods. When manufacturers seek to buy insulating oil for high voltage capacitors, they are looking for these precise attributes, which our phenyl xylyl ethane insulating oil reliably delivers.
