Experience the cutting edge technology of the new generation of oil-free transformer bushings with DRY TYPE Resin Impregnated Paper (RIP) and Resin Impregnated Synthetic (RIS) condenser bushings. By directly attaching premium crepe paper or specialized synthetic film to the conductor, these innovative solutions completely rethink insulation techniques while guaranteeing unmatched performance and dependability.

Constructed with great care, these bushings are the result of the flawless integration of conductive grading layers during the wrapping process. By doing this, a capacitive core is produced, which maximizes electromagnetic field control for better performance. After that, the wound core is subjected to an intense impregnation procedure that uses heat and vacuum to apply specifically made electrical resins, resulting in an entirely dry RIP/RIS active part solution.

The RIP/RIS active part assembly, which skillfully integrates direct molded silicone or hollow silicone insulators onto the active component, is a monument to precision engineering. Furthermore, mounting flanges and other metallic components receive careful attention through designated assembly techniques, guaranteeing optimal performance and seamless integration.

Key Specifications:

  • Rated Voltage: 24 kV — 245 kV
  • Rated Current: 400 A to 6300 A*
  • Insulation: Resin Impregnated Paper (RIP) / Resin Impregnated Synthetic (RIS)
  • Application: Transformer Outdoor
  • Type: Oil to Air
  • Insulator: Hollow Composite — Silicone
  • Standard: IEC 60137: 2017
  • Connection: Draw Lead/Draw Rod/Solid Conductor

Adhering to worldwide standards for quality and safety, these cutting-edge RIP/RIS bushings are made to enhance efficiency, dependability, and performance in outdoor transformer applications. Accept the progress of transformer technology.
