Why dry bushings?

Dry bushings

Why dry bushings?

The reasons are well known Fully dry, oil free technologiesFully dry, oil free technologies Excellent electrical, thermal and mechanical

characteristics Fire and explosion resistant Fire and explosion resistant

High safety for personal and equipment Environmental friendly Maintenance- and check-free Low life-time costs Fulfilling and even over passing the highest technicalFulfilling and even over passing the highest technical

requirements Transportation, storage and installation at any angle

Can be energized immediately after installation
