The radiator-fin tank (also known as a panel-radiator tank) is a classic pressure-bearing enclosure solution for medium- and large-capacity oil-immersed power transformers. Its core features include independently mounted external radiator assemblies and a matching top-mounted oil conservator for oil volume adjustment. It is designed for high-power heat dissipation capacity and long-term operational stability, making it a mainstream structural choice for power transformers rated at 35kV and above and 630kVA and above.

Its key advantages include outstanding high-power heat dissipation capability, flexible capacity expansion, strong operational stability, suitability for complex operating conditions, excellent maintainability, compatibility with professional maintenance scenarios, and broad environmental adaptability.

Typical applications

Main transformers in substations and converter stations at voltage levels from 35kV to 1000kV

Step-up transformers for offshore wind power, ground-mounted photovoltaic power generation, and energy storage power stations

Main plant transformers for large industrial and mining enterprises in metallurgy, chemicals, mining, and other industries, requiring 24-hour continuous heavy-load operation

Core power facilities with extremely high reliability requirements, such as railway traction substations, nuclear power plants, and hydropower plants
