Transformer Bushings – Why do they Fail?

Why Transformer Bushings Fail and How We Ensure Your Success at Indisol

At Indisol, as a epoxy insulator manufacturer,  we understand the critical role transformer bushings play in your operations. They’re the silent guardians, ensuring a safe and efficient connection between your transformer and the outside world. But like any vital piece of equipment, bushings can fail, leading to costly downtime and safety hazards.

That’s why we’re dedicated to providing you with the highest quality epoxy bushings on the market. We understand the three main categories that contribute to bushing failure:

  • Part Design: We adhere to the strictest industry standards and utilize polymers specifically chosen for their ability to withstand temperature fluctuations and stress. Our engineers meticulously design every aspect of the bushing, from creep distances to mounting methods, to optimize performance and longevity.
  • Polymer Selection: We don’t settle for just any epoxy. We formulate our own resins in-house, ensuring they possess the necessary mechanical strength and electrical insulating properties throughout their lifespan. From dielectric strength to heat resistance, we consider every factor to provide unmatched reliability.
  • Manufacturing Expertise: Here at Indisol, we take a vertically integrated approach. We don’t just manufacture bushings; from prototyping to industrialization we control the hole process in-house. This allows us to maintain complete control over quality and consistency throughout the entire production process. Every single bushing that leaves our facility undergoes rigorous testing to guarantee it meets our exacting standards.
