What to Confirm for a Prefabricated Substation Before Site Delivery

Release Time: 2026-08-11

Prefabricated substation foundation and earthing handover should turn site assumptions into a controlled project record before delivery is finalized. The EPC team needs agreed responsibility for civil interfaces, cable entries, earthing coordination, drawings, and acceptance boundaries; a product image cannot replace that project package.

Important: Do not treat a generic product layout as a foundation or earthing design. The responsible project parties must approve the civil, electrical, safety, and acceptance inputs for the actual site. Source: IEC 62271-202, used here only as a scope reference.

Part 1. What does pre-delivery handover decide?

The handover determines whether the equipment, site preparation, and project documents are being reviewed on the same basis. It identifies which interfaces have been approved, which party owns the remaining decisions, and which documents are needed before dispatch and site receiving.

IEC 62271-202 can provide a scope reference for prefabricated substation discussions. It does not determine a civil design for a particular installation.

Part 2. Why must responsibility be recorded first?

The owner, EPC contractor, civil designer, electrical designer, earthing designer, equipment supplier, and site team can each have defined inputs. A usable handover record names who supplies, checks, approves, and releases each project document.

That record prevents a delivery request from being mistaken for approval of work outside the supplier’s documented scope.

Part 3. Which civil interfaces need a controlled record?

The project package should identify the approved equipment location, applicable drawing references, cable approach, access and lifting interface, site datum, and any foundation information issued by the responsible civil team. The actual details must come from controlled documents, not from a generic article.

The related prefabricated-substation layout article helps structure access and cable-routing questions. It does not supply a site foundation solution.

Part 4. Why should earthing remain a project decision?

Earthing must be coordinated with the approved electrical design, fault and safety assessment, site conditions, and local requirements. The handover should state the assigned design responsibility and the information the equipment supplier needs to receive or return.

No universal earthing value or arrangement belongs in this article. The responsible engineer must verify the project-specific approach.

Part 5. How do cable and delivery interfaces connect?

Cable routes, entry locations, delivery access, lifting arrangements, and the site sequence should be coordinated before dispatch. A late change can affect more than the civil works because it can alter the documents, receiving plan, and interfaces held by several parties.

Use the prefabricated-substation transport planning article to organize logistics questions with actual drawings and delivery records. It does not establish transport limits for another unit.

Part 6. What belongs in the handover package?

Issue one controlled set of inputs before finalizing the delivery plan.

Buyer should provide or request	Why it matters to the handover
Approved one-line diagram and interface drawing	Connects equipment scope with the project electrical arrangement
Site location and civil drawing references	Shows the documents that govern site preparation
Cable approach and entry coordination	Lets each party review an agreed interface rather than an assumption
Earthing responsibility and review path	Keeps the safety-critical design decision owned by the project
Access, lifting, and delivery-sequence inputs	Aligns site receiving with actual logistics planning
Required approvals, records, and acceptance boundary	States what must be complete before handover is released

Part 7. Which JUBANG route fits the enquiry?

JUBANG’s prefabricated substation range is the starting point for an equipment discussion when the project team can share its controlled interface package. It should not be used as evidence that a particular foundation or earthing arrangement has been approved.

Send the drawing references, responsibility map, cable interface, delivery conditions, and document list through the JUBANG contact channel. The responsible project engineer should confirm site readiness before final release.

FAQs

What does foundation and earthing handover mean?

It is a controlled project record that assigns civil, cable-entry, earthing, document, and acceptance interfaces before equipment delivery is finalized.

Can a product image define the civil works?

No. A product image can show equipment context, while the responsible civil team must issue and approve the site-specific documents.

Who owns the earthing design?

The approved project responsibility map must identify the party that designs, reviews, and approves the earthing approach. A general equipment article cannot assign that responsibility.

Why should cable entries be discussed before delivery?

Cable routes and entry interfaces can affect site preparation, documents, equipment coordination, and the receiving sequence. They need agreement before dispatch planning is fixed.

What belongs in the project handover package?

Include approved drawings, site references, cable interfaces, the earthing responsibility path, access and delivery conditions, and the required approval and acceptance records.

Can JUBANG approve a site foundation from a web enquiry?

No. A web enquiry can start an equipment discussion, while the responsible project parties must approve the civil and earthing design for the actual site.
