Review point 01
Multiple suppliers leave the transformer and switchgear interfaces unclear.
Review the inverter output, transformer duty, HV/LV arrangement and cable interfaces as one configured package.

- Installation and enclosure conditions
- Document package before release
Review point 02
Outdoor installation creates enclosure, access and thermal questions.
Confirm enclosure construction, environmental conditions, ventilation, service clearance and cable entry before release.

FAQ
Questions buyers usually ask before sending an RFQ.
What capacity can the prefabricated substation support?
The planning range starts at 1000, 1600, 2000 and 2500 kVA. Final capacity, transformer duty and protection arrangement are confirmed from the inverter output, site conditions and project documents.
Can the low-voltage and high-voltage sides be customized?
Yes. The starting points are 0.4 / 0.69 / 0.8 kV on the LV side and 10 / 35 kV on the HV side; the final interface follows the approved project design.
Can oil-immersed and dry-type transformers both be considered?
Both can be reviewed. The choice depends on installation environment, cooling, access, fire strategy, maintenance and the approved project specification.
What should be sent for an initial review?
The inverter output, target capacity, HV/LV voltage, single-line diagram, installation environment, quantity, destination and document requirements provide the best starting point.
Can the configuration be adapted to our project drawing?
Yes. The product-family page is a starting point. Final enclosure arrangement, component selection, interfaces and documentation are confirmed against the approved drawing, load schedule or technical brief.
What should we send for a useful first quotation?
A single-line diagram, target ratings, quantity, installation environment, delivery destination and any required standards or document list will help the engineering review start with the right assumptions.
Can NEUTRON support OEM or project-specific assembly?
The review can include OEM, drawing-led assembly and project-specific integration requirements. Scope, interfaces, inspection points and document ownership are agreed before release.
Are the figures on this page a final product datasheet?
No. This page explains the product family and the information needed for selection. The approved datasheet, drawing and quotation are the controlling documents for a specific project.
