Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Compact Substations. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This prefabricated compact substation integrates high-voltage equipment, an oil-immersed transformer, and a low-voltage section within one enclosure. The three sections are arranged in independent compartments to support safer access, maintenance, and heat dissipation.
It is presented as a space-saving alternative to a conventional substation for power-distribution projects. The listed electrical configuration is 10/0.4 kV, with a maximum operating voltage of 12 kV on the high-voltage side. Available rated capacities are stated as 50–1600 kVA at 50 Hz.
The transformer uses ONAN oil-natural, air-natural self-cooling and an off-circuit tap changer specified as ±5% or ±2 × 2.5%. Listed insulation levels include a 35 kV one-minute power-frequency withstand voltage and a 75 kV lightning-impulse withstand voltage.
The stated allowable winding temperature rise is 65°C, and the listed noise level is 50 dB. The enclosure is described for outdoor use, while the product information identifies applications in power distribution, including urban grids, commercial zones, and industrial areas.
Custom configurations are stated to be available. Procurement note: the supplied information contains conflicting enclosure ratings. The title mentions IP33/IP54, while the technical table specifies IP43.
It also gives ambient ranges of both -35°C to +40°C and -25°C to +40°C, and includes broader transformer claims that may not describe this 10 kV compact-substation model.
Before ordering, obtain a model-specific technical schedule confirming the required protection degree, capacity, impedance, vector group, losses, temperature and altitude limits, internal equipment, dimensions, weight, interfaces, and applicable certification documents.
Buyers should also confirm whether quoted withstand levels, fuse ratings, tapping range, warranty coverage, and customization requirements apply to the selected configuration.
