The advantage:

Dry-type insulation: No oil-filling, No gas-filling. Means No leakage, easy maintenance.

No porcelain and Dry type means Anti-fire and Explosion proof.

RIF bushing:

Inner insulation: RIF (Resin Immersed Fibre)

External insulation: silicone rubber

Partial discharge: ≤5pC

Dielectric loss factor: ≤0.005

Other bushing expanded from transformer bushing, Such as: Oil-Oil bushing, Oil-Gas bushing, wall bushing , GIS bushing, reactor bushing, etc.
