400 kVA Three-Phase Pole-Mounted Transformer

Submit your 400 kVA project requirements for technical review and quotation.

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.
