Product Description
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.
