AGU-type oil-immersed inverted current transformer

The secondary winding of AGU-type oil-immersed inverted current transformer is put into the aluminum profiling torus, secondary wire runs through aluminum cylinder connected with aluminum torus and into secondary terminal box of housing. Primary winding runs through secondary winding center, and the capacitive main insulation is wrapped on the aluminum profiling torus and cylinder.Transformer head is designed according to the main insulation shape by three dimensional profiling optimized designs.The stainless steel bellow at the top of head will compensate the oil volume and can be as pressure releasing device in case of accident. External insulator is made of high strength porcelain.The product should be filled with high quality transformer oil. The product has the features of good appearance, advanced structure, excellent performance and reliable quality.
