Application:
GFRP dry transformer/Oil bushing(EBRO)bushings are applicable for the direct connection between the oil-filled transformers and the cable box or connection between the oil-filled transformers and other oil-filled equipment.Bushings can be installed horizontally.vertically or in any angles. To meet requirements on connection between the transformer and oil-filled equipment.the design and dimension of flanges and connecting terminals for bushings can be made as required by clients.
