Olharvest YB-12/0.4-2500 substation is designed as a single unit consisting of "high-voltage room + transformer room + low-voltage room". The assembly, wiring, and calibration tests are completed in the factory, and it can be installed on-site with the entire unit transported, significantly reducing construction duration and coordination costs for overseas projects.
The enclosure supports combinations of medium voltage platforms of 11kV/12kV/24kV/33kV/35kV and low voltage of 0.4kV. The transformer can be equipped with oil-immersed or dry type units; the low-voltage side can be pre-installed with metering, compensation, and protection units according to local distribution standards. 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 bidding 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 high-temperature and dusty areas, enhanced heat dissipation and dust prevention structures are used; for coastal salt spray sites, anti-corrosion coatings and stainless steel fasteners are employed. The color and labeling of the enclosure are customized according to the standards of the country where the project is located.
Delivery support includes batch production scheduling and weekly production schedule synchronization, in line with EPC node schedules; random spare parts packages and installation and commissioning documents are included with the enclosure, 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 card, 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 witnessing can be arranged as needed — from material selection to each process, traceable records are provided in document form.
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 time and labor; the whole-unit structure requires pre-defined transportation and lifting requirements. The segmentation of the enclosure-transformer, base stress, and on-site route are locked in with the general contractor during the drawing stage, allowing installation and power supply upon arrival.
Export delivery is a routine for this product line: multi-language nameplates, CE and ISO system documents, and inspection report catalogs are prepared at three levels: bidding, review, and factory inspection. Packaging and transportation are designed for either whole-unit or separate shipment options, and island logistics and lifting conditions are included in the detailed drawings stage. The quality control foundation of national high-tech enterprise, national energy-saving product promotion enterprise, 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 wrapped for shock resistance, accessories are packaged in wooden boxes, and packing list and lifting instructions are provided with the goods; whole containers can be shipped 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 scheduled to guide installation at major milestones; for distributors and EPC partners, installation training videos and bilingual manuals are provided to resolve on-site issues before operation begins.
