SEW

Wall bushings or roof bushings for air-insulated switchgear

  • Dimensioning of the bushing to the customer requirements
  • Optimized bushing size
  • Lowest possible building costs
  • Highest mechanical strength with fiberglass tube insulator

For high-voltage systems, we offer AC wall bushings that are designed for open-air / hall or hall / hall, depending on the application and design.

These are calculated and designed according to individual requirements. The bushings are offered dry-insulated.

  • SEW series bushings are always designed with dry filling.
  • The installation angle and the number of current transformers have a significant influence on the flange length and can be individually adjusted.

All bushings are designed and tested according to the IEC 60137 standard. Executions according to other country regulations are available on request.
