500 kVA Three-Phase Pole-Mounted Transformer
The HEAKOR 500 kVA three-phase pole-mounted transformer is listed for oil-immersed overhead distribution applications. The 500 kVA designation identifies the listed apparent-power rating; it does not by itself confirm the voltage combination, load suitability or installation arrangement for a project.
Listed product information
- Product type
- Pole-mounted
- Listed capacity
- 500 kVA
- Phase
- Three-phase
These details identify the listed product. The approved specification and drawing define the equipment supplied.

What must be confirmed for this 500 kVA transformer?
- Product identification: 500 kVA, three-phase, oil-immersed, pole-mounted transformer listing.
- Electrical system: primary and secondary voltages, frequency, vector group and neutral requirements.
- Design requirements: impedance, insulation level or BIL, tap range, losses and temperature-rise limits.
- Connections and protection: bushing arrangement, terminals, protection devices and required accessories.
- Installation conditions: support arrangement, equipment weight, mounting dimensions, access, ambient temperature and altitude.
- Approval scope: applicable standard and edition, utility specification, required tests and documentation.
500 kVA three-phase pole-mounted transformer questions
Does 500 kVA mean that the transformer can supply 500 kW?
Not necessarily. kVA expresses apparent power, while kW expresses active power; the relationship depends on the load power factor. Provide the load profile and any motor-starting or other special load requirements for engineering review.
Can this transformer be installed on any existing pole?
No. The proposed support structure, mounting details, equipment weight and site requirements must be checked for the installation. A 500 kVA three-phase pole-mounted transformer must not be selected on the assumption that an existing pole or support is adequate.
Are the primary and secondary voltages fixed?
This listing does not confirm a fixed voltage combination. State both voltages, the system frequency, winding connection and neutral requirements in your enquiry. The proposed configuration must be confirmed in the technical specification.
Can it replace another 500 kVA transformer?
An equal kVA rating alone is insufficient. Compare voltage ratio, frequency, vector group, impedance, insulation requirements, terminals and mounting details. Send the existing nameplate and drawings, and identify any changes to the load or site.
Is it approved for my utility or country?
Approval cannot be inferred from the product name. Provide the utility specification, required standards and certification requirements so compliance can be reviewed for the exact design. Any test reports and approval documents included in the order must be identified in writing.
How do I obtain a price and delivery schedule?
Provide the electrical requirements, installation details, quantity, destination and requested delivery date. Include the project stage and required documents. HEAKOR will review the enquiry before confirming the supply scope, price and delivery.

Use the contact form to send the core requirements and mention any available specification, nameplate or drawings. Mark undecided parameters as TBC so they can be identified during review.
Submit your 500 kVA transformer requirements. See the three-phase pole-mounted transformer category for an overview.
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.
Project documents
The right document. For the right model.
Tell us which documents your project needs. Availability and applicable scope are confirmed for the proposed model and configuration.
Outline and connection drawings
State the installation, cable-entry and clearance requirements you need to check.
Request for your projectTest and approval documents
Name the required tests, standard or approval, and the model or configuration concerned.
Request for your projectRequest 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.
