The 8000 kVA 1.0/35kV Three-Phase Renewable Power Transformer is a three-phase power transformer for substation, heavy industrial and utility duty where capacity and network conditions are specified more closely than for standard distribution units. Ratings are configured per the technical parameters below and confirmed against your system data.
Cooling method, vector group, impedance and tap range are engineered against your load profile and network parameters. Each unit is routine-tested before dispatch, and engineering support is available from enquiry through to commissioning.

Frequently Asked Questions
Where is a 8000 kVA Oil-Immersed Distribution Transformer normally installed?
It is built for utility, industrial and commercial distribution networks. This unit is configured with 0.35 kV primary and 1 kV secondary and ONAN cooling.
Can you change the rating or voltage of this oil-immersed distribution transformer?
Yes. Ratings are set from your project, not from a fixed catalogue. Send the single-line diagram and load list and we size the windings, tap range, cooling and protection to what the site actually needs. Vector group, frequency and terminal arrangement are confirmed on the drawing before anything is built.
Which standard applies to this oil-immersed distribution transformer, and is it certified?
The applicable standard and the clause set are agreed against your project specification before production starts. Where a project names IEC 60076 for the transformer or IEC 62271-202 for a prefabricated substation, we work to those clauses and ship the routine test report with the unit.
What cooling and protection are fitted?
Cooling is ONAN. Protection and monitoring are selected to the single-line diagram: winding and oil temperature indication, Buchholz relay or pressure relief where the design calls for it, and surge arresters on the terminals. Indoor or outdoor placement, enclosure rating and foundation details are fixed with your site conditions.
What information should we send for a quotation?
The single-line diagram, the load list, the system voltage and frequency, and the site conditions that affect the design – altitude, ambient temperature range, indoor or outdoor, enclosure rating. With that we come back with a drawing and a price. If you only have a rating in mind, send that and we will work the rest out with you.
Typical Applications
The 8000 kVA 1.0/35kV Three-Phase Renewable Power Transformer is specified in projects such as:
- Substation step-up and step-down duty
- Heavy industrial process power supply
- Generator step-up for small plant and embedded generation
- Grid interconnection where impedances are specified

- Type test certificates from accredited laboratories available on request
Technical Drawing
Delivery, Warranty & OEM Support
- Typical lead time: 30 days from order confirmation for standard ratings; custom configurations are confirmed at order stage
- Warranty: 2 years, with technical support available throughout the service life
- OEM / ODM supported: private labelling, nameplate language and document packages
- Seaworthy export packing; documentation set includes routine test reports, installation manuals and general arrangement drawings
