400 kVA Three-Phase Pole-Mounted Transformer

The HEAKOR 400 kVA three-phase pole-mounted transformer is listed as an oil-immersed design for overhead distribution projects. For a new installation or a capacity upgrade, submit the load requirements together with the support arrangement and site constraints. The proposed configuration needs electrical and installation review before an order is placed.

What should I check before ordering 400 kVA equipment?

For a 400 kVA three-phase pole-mounted transformer, confirm the following before finalizing the order:

  • Electrical requirements: primary and secondary voltages, frequency, vector group, neutral arrangement, impedance and insulation levels.
  • Operating conditions: load profile, ambient temperature, altitude, losses and temperature-rise requirements.
  • Installation and supply: support and mounting details, terminals, taps, protection, accessories and required documents.
  • Compliance: the required standard and edition, destination-country and utility requirements, certification scope and specified tests.

Buyer questions and answers

Can a 400 kVA unit replace a smaller transformer?

A higher kVA rating alone does not establish a suitable upgrade. Compare the voltage ratio, frequency, winding connections, impedance, protection and mounting arrangement. Describe the planned load increase and provide the existing nameplate and drawings.

What installation information is needed?

Provide the support layout, available space, terminal clearances and lifting access. Obtain the proposed equipment weight and mounting drawing for review by the project engineer. Do not assume an existing structure can support the replacement.

How should I compare quotations?

Ask suppliers to identify the same ratings, accessories, tests, drawings and delivery scope. Record deviations from the specification and distinguish the requested delivery date from a confirmed commitment.

Does the product name confirm certification or utility approval?

No. Compliance and approval must be established for the exact proposed design and destination. Identify mandatory certificates, test documentation and utility requirements at the enquiry stage; none should be assumed from the capacity or product category.

Before requesting a quotation

Confirm the fit for your project.

A product name or capacity is the starting point. Include these requirements so the proposal can be reviewed against your project.

01

Electrical requirements

Capacity, primary and secondary voltages, phase, frequency, and any specified connection, impedance or tap requirements.

02

Installation requirements

Provide the mounting arrangement, connection requirements and serving utility specification. Include site constraints.

03

Documents and supply scope

State the required drawings, tests or approvals, quantity, destination and project schedule. Identify any mandatory requirements before quotation.

What if some specifications are not known yet?

Send the information you have and mark unknown items as to be confirmed. For a replacement, an existing nameplate, equipment photographs and site constraints help define the review. Final ratings and supply scope must be agreed in the quotation and approved documents.

Request documents for your proposed configuration

Include the model or product type, capacity, voltages, frequency and destination. Ask for the report number, date and test scope so you can check that the documents match the proposed configuration. An individual report does not establish certification for every model or destination.

When reviewing a document, match the legal entity, model, rating, applicable scope and issue date to your proposed equipment.
