STARON bushings for IEEE market

STARON bushing with purple background

For applications from 25 kV to 500 kV, up to 3000 A

With the STARON bushing we want to introduce a more cost efficient traditional solution, fully reflecting the technical requirements of IEEE standard. 

Product overview

Type STARON according to IEEE C57.19.01-2017

STARON is the new generation of oil-impregnated paper (OIP) bushings, designed and tested according to IEEE C57.19.01-2017 and IEEE C57.19.00-2004. The portfolio is available from 25kV up to 500kV system voltages in the most common current ratings.

Main features:

  • Air side insulator: porcelain cemented into the flange for increased cantilever withstand capability or composite silicon insulator
  • Oil side epoxy insulator providing high impact resistance and reduced size
  • Embedded end shield in the epoxy insulator eliminates external shielding in draw lead applications up to 230 kV and provides greater internal clearances
  • High electrical and thermal margins
  • Horizontal transportation and storage
  • Qualified for optional ambient temperature down to -60°C
  • Full portfolio available from 25 kV to 500 kV

Advantages:

  • STARON bushings are designed according to latest IEEE standard revisions and customer expectations linked to market evolution, in addition to long experience and feedback gained in the IEC business
  • The design philosophy of STARON considers the most stringent voltage levels between IEC and IEEE and creates superior design in the dimensional requirements of the IEEE standard
  • STARON is the perfect solution to fit on your transformer or reactor applications, either for new installation or replacement of an existing bushing
  • Replacement: 

        - Draw lead adapters to allow replacement of old draw lead                    bushings without modification of the existing stud/bolt & cable

        - Customizable solution for specific operating conditions
