For professionals in the electrical and electronics industries, selecting the right dielectric fluid is paramount to ensuring the longevity and optimal performance of critical equipment. Dielectric oils, also known as insulating oils, play a dual role: they act as an insulator, preventing electrical discharges, and as a coolant, dissipating heat generated during operation. As a leading manufacturer and supplier, we understand the nuances of these essential fluids and aim to guide you through the selection process. Understanding Key Properties
When evaluating dielectric oils, several technical specifications are crucial. These include:
  • Appearance: Typically clear and transparent, indicating purity.
  • Dielectric Strength: This is a measure of the fluid's ability to withstand voltage without breaking down. A higher dielectric strength is critical for preventing arcing and ensuring safety. For example, our PEPE dielectric oil offers a breakdown voltage of ≥70 KV, making it suitable for high-demand applications.
  • Pour Point: This indicates the lowest temperature at which the oil will still flow. For applications in colder climates or for components operating at low temperatures, a low pour point, such as the -60°C offered by our PEPE dielectric fluid, is essential.
  • Flash Point: The flash point signifies the temperature at which the oil's vapors can ignite. A high flash point is a crucial safety feature, minimizing fire risks. Our product boasts a flash point of 140°C.
  • Viscosity: Affects the oil's ability to flow and dissipate heat. Lower viscosity at operating temperatures generally aids in better cooling.
  • Chemical Stability & Antioxidant Properties: These ensure the oil maintains its performance characteristics over extended periods without degrading.
Applications in Focus
Dielectric oils are indispensable in several key areas:
  • Capacitors: They provide vital insulation and cooling, especially in full-film capacitors. Our PEPE dielectric fluid is particularly advantageous for low-temperature capacitor applications.
  • Transformers: As a coolant and insulator, transformer oil is fundamental to the operation of electrical transformers, protecting windings and core components.
  • Electrical Switchgear: Used in circuit breakers and other switchgear to suppress electrical discharges and ensure safe operation.
  • Other Electrical Equipment: From high-voltage cables to various custom electrical apparatus, these oils are critical for insulation and thermal management.
