Engineered for KYN28 switchgear compartments. Featuring internal shielding screens for optimal electric field control and superior bending strength up to 12.5kN.
A conductive screen equalizes potential distribution.
Prevents corona and breakdown at the flange interface.
Rated from 4kN up to 12.5kN bending load.
Void-free epoxy resin ensures structural integrity under stress.

We have molds for standard busbar sizes (e.g., 60x10, 80x10, 100x10, 120x10). For non-standard sizes, we can customize the aperture window.
Yes, the bushing comes pre-assembled with a metal mounting plate (Steel or Aluminum) with grounding terminals.
For rated currents >1500A, we strongly recommend Aluminum (non-magnetic) plates to prevent eddy current heating. Below 1500A, Steel is sufficient and cost-effective.
