Parts Of Product
| Core | 1 | Power transformer core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet |
2 |
The material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm. | |
| 3 | Power transformer silicon sheet fabrication adopts “no-upper yoke-lapped’ technology and all lapped joints of the silicon sheet are 45 full-miters | |
| 4 | Effectively improves no-load performance and reduces noises. |
| Coil | 1 | The high-voltage(HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed. |
| 2 | All stays and pads are chamfered to keep highly reliable insulation. | |
| Oil tank and accessories | 1 | Power transformer tank wall adopts wide steel sheet |
| 2 | Which will be folded into corrugated structure without splicing | |
| 3 | In this way welds aredecreased and mechanical strength is enhanced | |
| 4 | The corrugated wall has diverging effect, and thus plays arole in decrease of noise. |
