S22-M 10/0.4kV Oil Immersed Transformer
Category：
Detail
The body (winding and iron core) of the oil immersed transformer is installed in an oil tank filled with transformer oil, which is welded with steel plates. The oil tank of small and medium-sized transformers consists of a box shell and a box cover. The transformer body is placed inside the box shell, and the box cover can be opened to lift out the body for maintenance.
The fully sealed transformer eliminates the traditional conservator tank by integrating corrugated tank fins as both heat dissipation components and expansion elements.These fins dynamically expand and contract in response to oil volume variations,ensuring complete isolation from the external atmosphere to prevent oil degradation,insulation moisture ingress,and aging,thereby significantly enhancing operational reliability. The core utilizes premium cold-rolled silicon steel laminations to optimize magnetic flux distribution, effectively reducing noise levels and energy losses.Windings are constructed with high-strength enameled or paper-insulated conductors in cylindrical or disc-type configurations,achieving uniform ampere-turn distribution and robust insulation for exceptional short-circuit resistance.All internal fasteners employ self- locking nuts to withstand vibration during transportation and operation.The tank undergoes phosphating treatment and is coated with a triple-protection layer(anti-humidity,anti-mold,anti-salt spray),making it ideal for harsh environments such as metallurgical plants,mining facilities,and petrochemical complexes.
Notes:
1.Customized products with capacities beyond those listed in the table can be manufactured upon request,with technical parameters tailored to specific requirements.
2.Specialized designs are available to accommodate diverse operationalenvironments.
3.Short-circuit impedance values may deviate from the table specifications based on project needs.
4.The final dimensions of the transformer shall be confirmed based on the approved technical drawings after the contract is signed.
