Single-phase pad-mounted transformers usually include insulated windings on the high-voltage side and low-voltage side, oil-immersed insulation systems, and related protection and control devices, such as fuses, disconnectors, overvoltage protection devices, etc.This type of transformer is suitable for smaller-scale power distribution and is often used for residential and small commercial purposes. They have a small size and can be easily installed in tight spaces.
