Oil-immersed transformers vs. dry-type transformers: Why are oil-immersed transformers more advantageous in photovoltaic applications?

Compared with dry-type transformers, 3-Phase Oil Immersed Type Step up Transformer for Solar Plants has the following characteristics and advantages in photovoltaic applications:

1. High reliability and long lifespan: The insulating oil provides excellent insulation and moisture-proof protection, preventing the internal windings from aging and ensuring a design life typically ranging from 20 to 30 years, matching the lifespan of photovoltaic power stations.

2. Strong overload capacity: The insulating oil has a large heat capacity and can withstand short-term overloads (for example, when the light suddenly intensifies) without causing a sharp increase in temperature, demonstrating good stability.

3. Efficient heat dissipation performance: The circulation of the oil (either natural or forced) can effectively remove the heat generated by the windings and core, and disperse it through heat sinks into the air, making it suitable for large-capacity applications.

4. High cost-effectiveness: For large-scale projects (typically >1MW), the initial cost and life cycle cost of oil-immersed transformers are usually lower than those of dry-type transformers of the same capacity.

5. Robust structure: The casing is sturdy and can adapt to the harsh environmental conditions in the outdoor environment.
