● Oil-immersed transformer is widely used in a variety of scenarios, including substations, high-rise buildings, data centers, wind power and photovoltaic power stations.

● Substation: Oil-immersed transformer is the core equipment in substation, responsible for voltage conversion and regulation, to ensure the stable operation of the power grid.

● High-rise buildings: oil-immersed transformers are used to reduce the high voltage power of the main distribution network to the voltage level required by the individual floors and users.

● Data center: oil-immersed transformers provide stable power conversion to ensure the operation of servers and storage devices.

● Wind and photovoltaic power stations: oil-immersed transformers are used to improving electricity generated from renewable sources to a suitable voltage level for transmission to the grid.

In addition, oil-immersed transformers are also suitable for outdoor environments with appropriate fire and explosion protection measures, as well as applications requiring heavy loads and high voltages
