For procurement managers and R&D scientists in the electrical component industry, selecting the correct insulating oil for capacitors is paramount. The performance, reliability, and lifespan of a capacitor are intrinsically linked to the quality and suitability of its dielectric fluid. This guide aims to demystify the selection process, focusing on crucial parameters and highlighting why Phenyl Xylyl Ethane (PXE) oil is an increasingly preferred choice among manufacturers.

Capacitor insulating oils, often referred to as dielectric fluids, perform several critical functions. They provide electrical insulation, prevent corona discharge, facilitate heat dissipation, and protect internal components from moisture and oxidation. The choice of oil directly impacts these functions, influencing the capacitor's ability to operate efficiently and safely under various conditions.

When evaluating insulating oils, several key technical specifications warrant close attention. These include dielectric strength (often measured by breakdown voltage), dissipation factor, volume resistivity, viscosity, flash point, and pour point. Additionally, compatibility with other capacitor materials, particularly polypropylene film, is a significant consideration. For buyers looking to purchase high-quality materials, understanding these parameters is the first step.

Phenyl Xylyl Ethane (PXE) oil, with its CAS number 6196-95-8, has emerged as a high-performance option. PXE oil is renowned for its excellent physical and chemical properties, coupled with superior dielectric characteristics. A standout feature is its remarkable compatibility with polypropylene film, a common dielectric material in modern capacitors. This synergy allows for more efficient capacitor designs and improved operational performance.

Key performance indicators for PXE oil often include a high breakdown voltage (e.g., ≥70 KV), a low dissipation factor (≤0.001 at 90°C), and high volume resistivity (≥1.0*10¹² Ω.m). Its low pour point (≤-40ºC) also makes it suitable for applications in colder environments where maintaining fluidity is crucial. These attributes collectively contribute to the oil's effectiveness in film-paper composite and low-voltage full film capacitors.

For businesses seeking to buy PXE insulating oil, identifying a reliable manufacturer and supplier is crucial. A reputable supplier will not only offer competitive pricing but also ensure consistent quality and a stable supply chain. When you inquire about PXE oil price in China, look for manufacturers who provide detailed technical specifications, adhere to industry standards like GB 21221-2007, and possess robust quality control systems. Requesting samples for internal testing is also a standard practice for procurement managers to verify suitability.
