Epoxy Bushings: Demand, Types, and Applications

Epoxy bushings are prominently used in various electrical equipment such as transformers, switchgear, circuit breakers, and capacitors. Their demand has been on the rise due to the growth in the power sector and the requirement for reliable electrical devices.

Indisol, a key manufacturer and supplier of epoxy bushings, adheres to strict quality standards, ensuring the production of high-quality products. These bushings find applications in the power transmission and distribution sector, providing insulation and support for high voltage conductors.

Additionally, epoxy bushings are vital in industrial applications like motor control centers, variable frequency drives, and power distribution units. They’re also used in the railway industry, specifically in electrifying railway lines and constructing locomotives.

Various Kinds of Epoxy Bushings and Their Uses:

  1. Solid Epoxy Bushings: Made of a single piece of epoxy resin, they provide excellent electrical insulation and mechanical strength. Commonly used in high voltage equipment.
  2. Split Epoxy Bushings: Designed for installation around existing conductors without removing them, these are often used for upgrading power transmission and distribution systems.
  3. Flange Mount Epoxy Bushings: Designed for surface mounting, they have a flange that allows them to be bolted or welded in place, providing a secure connection in high voltage transformers and similar equipment.
  4. Threaded Epoxy Bushings: Installed into a threaded hole or stud, these provide a secure and reliable connection and are often used in high voltage equipment like circuit breakers.
  5. Tapered Epoxy Bushings: Designed for installation in a tapered hole, they ensure a secure and tight fit, commonly used in high voltage transformers and similar equipment.
  6. Radial Epoxy Bushings: These provide support and insulation for bent or curved conductors, typically used in equipment where conductors must fit into tight spaces.
  7. Elbow Epoxy Bushings: Installed at the junction of two conductors, they insulate and support connections in high voltage equipment such as transformers and switchgear.

Each type has unique properties and applications, and the selection depends on the specific needs of the electrical setup.
