The YBM Series Prefabricated Substation is a compact and integrated power distribution solution designed for medium voltage electrical systems. It combines the main medium voltage, transformer and low voltage distribution equipment within a compact enclosure, helping simplify installation and reduce the space required for a conventional substation.

The prefabricated substation can be configured with an oil immersed transformer or dry type transformer, together with suitable medium voltage switchgear and low voltage distribution equipment. The internal arrangement can be customized according to the customer's voltage level, transformer capacity, electrical configuration and project requirements.

Designed for outdoor installation, the compact substation is suitable for industrial plants, commercial buildings, infrastructure projects, solar power systems, wind power projects and other power distribution applications.

Why Choose a Prefabricated Substation?

• Integrated Design: Combines medium voltage switchgear, transformer and low voltage distribution equipment into one compact power distribution unit.

• Space Saving: The compact structure helps reduce the installation footprint compared with separately installed electrical equipment.

• Faster Installation: Major electrical components can be assembled and tested at the factory, reducing on site installation work.

• Flexible Configuration: Transformer type, MV switchgear, LV distribution equipment and electrical parameters can be configured according to project requirements.

• Outdoor Application: Designed for outdoor power distribution applications with a suitable enclosure and protection configuration.

• Complete Power Distribution Solution: Can be supplied as an integrated substation for industrial, commercial and renewable energy projects.

• Low Voltage System: Confirm the required secondary voltage, main breaker rating and number of outgoing circuits.

• Cable Entry: Confirm cable entry and connection requirements according to the site layout.

• Installation Environment: Provide information about the outdoor installation location and environmental conditions.

• Enclosure Requirements: Confirm the required protection and enclosure configuration according to the project environment.

Installation & Handling

• Install the prefabricated substation on a suitable and level foundation.

• Ensure sufficient space around the enclosure for operation, inspection and maintenance.

• Provide suitable cable trenches or cable entry arrangements according to the approved drawings.

• Check all electrical connections and grounding before commissioning.

• Use the designated lifting points when loading, unloading and positioning the substation.

• Do not lift the equipment from unauthorized components or enclosure sections.

• Keep the equipment protected from unnecessary impact during transportation and installation.

• Installation and commissioning should be carried out by qualified electrical personnel according to applicable local regulations and project requirements.

Frequently Asked Questions (FAQ)

What is a prefabricated substation?
