The power transformer functions as power transmission, voltage conversion and insulation isolation, and is widely applied to power supply technology and power electronic technology as a main soft magnetic electromagnetic component. Depending on the amount of power delivered, power transformers can be divided into several steps: the power is more than 10kVA, the medium power is 10 kVA-0.5 kVA, the small power is 0.5 kVA-25 VA, and the micro power is less than 25 VA.

Power transformers are used in almost all electronic products and have a simple principle but have different requirements depending on the winding process of the transformer in different applications (different uses). The transformer mainly has the following functions: voltage transformation; impedance transformation; isolating; voltage stabilizing (magnetic saturation transformer), etc., and the shape of the iron core commonly used for the transformer generally includes E-type and C-type iron cores.

In a power distribution system outside a hydropower station, small power transformers such as AC 220V-to-DC 12V, DC V or DC48V are needed for outdoor lamps. These small power transformers are often installed outdoors on site, and exposed power transformers do not have waterproof, dustproof and moistureproof effects, which may cause damage to the power transformers and reduce their service life. When the outdoor rains, the power transformer may be damaged due to leakage of rainwater.
