YB-12/0.4-2500 substation pre-assembled (European style), integrating high-voltage switchgear, transformer and low-voltage distribution cabinets; delivered as a complete box, with third-party inspection reports, suitable for rapid installation in industrial parks and urban distribution networks.
The YB-12/0.4-2500 pre-assembled substation is designed as a three-compartment system: high-voltage room + transformer room + low-voltage room. It is assembled, wired, and calibration tests completed in the factory. Just transport the entire unit to the site, and basic installation and power supply can be carried out, significantly reducing construction duration and coordination costs for overseas projects.
The box supports the combination of medium-voltage platforms of 11kV/12kV/24kV/33kV/35kV and 0.4kV low-voltage systems. The transformer can be equipped with oil-immersed or dry type. On the low-voltage side, metering, compensation, and protection units can be pre-installed according to local distribution specifications. The third-party inspection reports cover models such as YB-12/0.4-2500 and YB-40.5/0.69-6500, which can be directly referenced for bid qualification pre-screening.
The key configurations and selection range are shown in the parameter table below.
Environmental adaptation: For island logistics scenarios, separate transportation and on-site quick installation solutions are provided; in hot and dusty areas, enhanced heat dissipation and dust prevention structures are used; at coastal salt spray sites, anti-corrosion coatings and stainless steel fasteners are applied. The color and markings of the box are customized according to the regulations of the country where the project is located.
Delivery support includes batch production scheduling and synchronization with weekly production schedules, in line with EPC node scheduling. Random spare parts packages and installation and commissioning documents are included in the box, and nameplates and drawings are available in multiple languages.

Quality control covers the entire manufacturing process: rolled silicon steel is precisely cut on the slitting line, core stacking is inspected section by section according to the process cards, the automatic winding machine completes winding before entering the body assembly and vacuum impregnation (VPI) station. Routine tests are completed before leaving the factory, and type tests and third-party witness tests can be arranged as needed — from material selection to traceable records of each process, all are documented and sent with the product.
The value of rapid implementation is particularly evident in overseas projects: the on-site electrical construction interface is reduced from "three professional intersections" to "installed in one go", saving both construction time and labor. The whole-box structure requires pre-defined transportation and lifting requirements. The segmentation of the box-transformer, base stress, and arrival route are locked in with the general contractor during the drawing stage, allowing power supply to be started immediately upon arrival.
Export delivery is a regular part of this product line: multi-language nameplates, CE and ISO system documents, and inspection report catalogs are prepared at three levels: bid, review, and factory inspection. Packaging and transportation are designed according to two options: whole box or separate pieces. Island logistics and lifting conditions are included in the detailed drawings at the design stage. The quality control foundation of national high-tech enterprises, national energy-saving product promotion enterprises, and qualified suppliers of State Grid/China Southern Power Grid also serves the review rhythm of overseas projects.
Packaging and transportation follow export practices: the main body is protected and bundled, accessories are packaged in wooden boxes, and a packing list and lifting instructions are provided with the product. Whole containers can be delivered in batches according to project schedules, and the sea shipping period is provided together with the quotation to avoid waiting for goods on-site.
Default commitments for after-sales service: Remote technical support within the warranty period, random spare parts packages, and engineers can be invited to guide installation at major milestones. For distributors and EPC partners, installation training videos and bilingual manuals are provided to resolve on-site problems before operation starts.
En el sitio del proyecto en el extranjero, el plazo de construcción es corto y los recursos de construcción son escasos. Los costos de desmontaje y rework para la instalación separada son mucho mayores que los de entregar todo el equipo en una sola caja.
