S11 630kva 10kv Oil Immersed Transformer Copper Coil 3 Phase Distribution Transformer
The iron core of S11-M series low loss energy-saving transformer produced by our company adopts laminated structure. This product is based on fully absorbing the advanced technology and process of domestic oil immersed transformer, combined with the technical level of our company, putting the reliability of the product in the first place, at the same time, the no-load loss and no-load current of the product are greatly reduced.
Strong Ability Of Withstanding Short-Circuit The coil adopts a low axial short-circuit force structure. When the transformer is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit. |
304 Stainless Steel Material All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformer. |
High-Quality Sealing Rubber Ring Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring. |
High-Reliability Support Structure The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited. |
A Lower Magnetic Flux Density This not only reduces the no-load loss of the transformer, but also ensures that the core flux is not saturated when the transformer is operating under voltage, so that the third harmonic of the transformer is small. |

1) When used together with fiber materials, the insulation performance is good, the insulation distance can be reduced, and the cost can be reduced.
2) Transformer oil has low viscosity and good heat transfer performance.
3) It can well protect the iron core and winding from the influence of moisture in the air.
4) Protect insulating paper and pressboard from oxygen, reduce the aging of insulating materials and prolong the service life of transformers.
Except for some medium and small capacity transformers and gas transformers for special purposes, the vast majority of large and medium-sized transformers still use transformer oil as the cooling and insulation medium.
The insulation of transformers impregnated with transformer oil has a heat-resistant grade of A and a long-term working temperature of 105 ℃.
