Selection and Application:
The Compact Secondary Substation suits projects where a conventional substation requires too much space. Its footprint is about one-tenth of a conventional substation, making it applicable to city streets, residential communities, industrial parks, commercial centers, transportation hubs, and landscaped areas. It can also be considered where fire separation distance is insufficient, site space is limited, or an existing distribution room cannot be expanded.
Manufacturing and Custom Options:
The equipment is factory prefabricated, with on-site installation taking 5–8 days, reducing site construction work. Compared with a conventional substation, overall investment can be reduced by about 40%–50%. OEM/ODM cooperation is available after the required authorization is completed. Buyers can submit technical drawings, parameter schemes, and project requirements for confirmation before design and production.
Quality Control:
who choose us?
Hebei Biot Electric Co., Ltd. applies quality control under the ISO9001 quality management system, covering incoming material inspection, multiple in-process inspections, and finished-product testing. Before packaging, technical personnel complete 100% electrical performance testing. Buyers may also arrange third-party on-site inspection before shipment.

Packaging and Delivery:
Equipment receives rust-prevention treatment as appropriate and is packed in reinforced export solid-wood cases for ocean transportation. Standard products generally require 10–20 working days for production; customized products generally require 20–35 working days depending on drawings and technical requirements. EXW and FOB terms are supported.
Purchasing / FAQ Information:
The minimum order quantity for a complete substation set is 1 unit. Free complete-unit samples are not provided, although core-component samples may be discussed and sample charges agreed separately. Standard orders use 30% advance payment and 70% before shipment; customized orders use 50% advance payment and 50% before shipment. Installation guidance, operator training, technical consultation, and after-sales support are available.
Inquiry Guidance
For a Compact Secondary Substation quotation, send the required capacity, technical drawings or parameter scheme, installation conditions, quantity, and delivery requirements. These details allow the configuration to be confirmed before production.
