Oil Immersed Power Transformer
This transformer is an oil-immersed transformer model that meets Tier 1 energy efficiency standards. It is a product independently developed by our company according to energy efficiency standards and is a high-efficiency, energy-saving transformer encouraged and prioritized for procurement by the State Grid. It has advantages in research and design, production and manufacturing, and operation and maintenance.
This transformer is an oil-immersed transformer model that meets Tier 1 energy efficiency standards. It is a product independently developed by our company according to energy efficiency standards and is a high-efficiency, energy-saving transformer encouraged and prioritized for procurement by the State Grid. It has advantages in research and design, production and manufacturing, and operation and maintenance.
The new standard came into effect on June 1, 2021. All new transformers must meet the new energy efficiency requirements, with the minimum requirement being the new level 3 energy efficiency rating (S13 oil-immersed transformer).
- Transformers have good oil insulation performance and heat conduction performance, and the transformer oil is cost-effective.
- They can solve the problems of large-capacity transformer heat dissipation and high-voltage insulation.
- Oil-immersed transformers are fully sealed, effectively preventing insulation oxidation and are not prone to aging.
- The cores of transformers use higher-grade silicon steel sheets, increasing the core cross-sectional area, making them more energy-efficient.
