- The Compact Package Substation is intended for 12kV/0.4kV distribution systems in 400kVA, 500kVA, and 630kVA capacities.
- Its footprint is about one-tenth of a conventional substation, helping projects where fire separation distance, terrain, or available installation area limits traditional layouts.
- Suitable settings include residential communities, industrial parks, commercial centers, city streets, and retrofit projects where an existing distribution room cannot be expanded.

Electrical Layout and Access:
- The high-voltage and transformer sections use a fully enclosed high-voltage switchgear arrangement with a dry-type transformer.
- FRC combined electrical apparatus is used on the high-voltage side.
- The enclosure uses aluzinc-coated steel sheet with a fluorocarbon finish; the supplied data states corrosion resistance of more than 25 years. Ventilation openings in the base and heat-dissipation passages in the top cover address thermal management.
- Maintenance planning should reserve more than 1000mm of door-opening space, with a door-opening angle of at least 90°.
Configuration Choices:
- Ring-network, terminal, and dual-power schemes may be confirmed according to the project distribution design.
- Low-voltage outgoing circuits can be arranged in 4–6 ways, while reactive power compensation is set at 15% of main transformer capacity.
- Custom production may cover capacity, power-supply mode, outgoing-circuit quantity, site conditions, and buyer technical drawings.
Verification Before Shipment:
- Raw materials are inspected before entering production, and manufacturing stages are checked through multiple in-process inspections.
- Finished equipment undergoes electrical performance testing, with 100% electrical performance inspection completed before packing.
- Buyers may appoint an independent third party for on-site pre-shipment inspection.
Order Planning:
- Factory-prefabricated construction reduces site work, with approximately 5–8 days from on-site installation to commissioning.
- The supplied data states that investment may be about 40%–50% lower than a conventional substation arrangement.
- Export orders use protective treatment and reinforced solid-wood cases. Customized products generally require 20–35 working days according to drawings and non-standard requirements.
- The Compact Package Substation is available under EXW and FOB delivery terms.
