YBM Series Prefabricated Substation is a complete power transformation and distribution unit that integrates high-voltage switchgear, transformer, and low-voltage switchgear. It features an attractive appearance, flexible configuration, and compact structure. It can be equipped with either a high-voltage load switch or intelligent interfaces. This series offers multiple structural design options.

Key Features

Composed of high-voltage compartment, transformer compartment, and low-voltage compartment, with reliable "five-prevention" interlocking functions to ensure safety; standard, compact, and alternative standardized solutions are available;

High-voltage switchgear options include fully insulated SF₆ gas-insulated RMU, solid-insulated RMU, or vacuum RMU, and can be fitted with DTU to achieve motorized and automated functions;

Transformer can be dry-type or oil-immersed, featuring low loss, low noise, low temperature rise, strong overload capacity, excellent short-circuit resistance, and high impact withstand capability;

Low-voltage compartment provides complete low-voltage switchgear functionality, fully customizable to user requirements;
