SM11 35/0.4KV Oil immersed Power transformer

The oil-immersed transformer is a type of power transformer that uses insulating oil as both a coolant and an
insulating medium. The oil helps dissipate heat generated during operation and provides electrical insulation
between the windings and the transformer core. This design is widely used in power distribution and
transmission systems due to its reliability and efficiency.
The transformer with a voltage rating of 35/0.4 kV is typically used in distribution networks. The high-voltage
side (35 kV) is connected to the power grid, while the low-voltage side (0.4 kV) supplies electricity to endusers,
such as residential, commercial, or industrial facilities. This voltage configuration is ideal for stepping
down medium voltage to low voltage for local consumption.
Oil-immersed transformers are known for their robust construction and ability to handle high loads. They
are designed with a core made of laminated silicon steel to minimize losses and windings made of copper
or aluminum for efficient energy transfer. The insulating oil also enhances the transformer's lifespan by
protecting the internal components from moisture and oxidation.
