33 kV distribution transformers for export grids

30 to 2500 kVA, built to IEC 60076 or your local grid code, with 33 kV primary and the secondary voltage your network actually uses.

Where 33 kV is used

The distribution voltage of a lot of export grids

33 kV is common in African, Middle Eastern and South Asian distribution systems, and it is also the collector voltage inside many wind and solar plants. Units at this level are rarely a catalogue item — the impedance, tapping range and secondary voltage get set by the local grid code.

That is why we do not publish a 33 kV price list the way we do for 11 kV. Send the specification and we quote against it, including the loss figures and the test evidence your tender asks for.

Typical configurations

Starting points, not a closed list. If your grid code says something different, we build to it.

Configuration	Typical capacity	Where it is used
33 / 0.415 kV	100 – 1000 kVA	Distribution substation feeding a low voltage network
33 / 0.433 kV	100 – 1000 kVA	Networks standardised at 433 V
33 / 11 kV	1000 – 2500 kVA	Step-down between two medium voltage levels
33 kV wind farm collector	1250 – 2500 kVA	Collector substation inside a wind plant

Why there is no published price

Two units at the same rating can differ by 20% once the impedance, tapping range, loss level and secondary voltage change. Publishing one number would be misleading, so at this level we quote against your document.

What we can tell you before you ask: the 11 kV range has published ex-works prices from USD 1,821 for 50 kVA, and a 33 kV unit of the same rating sits in a similar band, moving with the specification.

Ordering terms

Term	Detail
MOQ	10 units per order, mixed ratings accepted
Lead time	Quoted per order; longer than the 11 kV standard range
Price basis	Ex-works or FOB, USD
Documentation	Drawings, routine records, type test and efficiency reports on request
Branding	Your nameplate, manual and packing
Payment	T/T 30% deposit, 70% before shipment; L/C at sight for tender orders

33 kV questions buyers ask

Question	Answer
Can you build to IEC 60076?	Yes, that is our reference standard for this range. Send the clause list and we will confirm which reports we hold and which need a project-specific test.
Do you supply 33/11 kV two-winding units?	Yes, typically 1000–2500 kVA.
Is 60 Hz available?	Yes, on request.
Can the impedance be set to our grid code?	Yes. Impedance, tapping range and temperature rise are design inputs, not fixed catalogue values.
What is the lead time?	Quoted per order. The 11 kV standard range runs 30–45 days after deposit; 33 kV units usually take longer.

Working at 11 kV instead? See 11 kV distribution transformers, or custom builds to your drawing.

Send the grid specification

Voltage ratio, capacity, impedance, loss limits and the standard you must meet. We will answer point by point with a price.
