Design features

What the design is built around

Low-loss magnetic core

Cold-rolled grain-oriented silicon steel and a stepped core reduce no-load loss and audible noise.

Sealed tank construction

Welded tank, quality-gasketed cover and pressure-tested seals reduce oil leakage risk in outdoor duty.

Thermal margin for hot climates

Cooling surfaces and oil volume are selected for high ambient temperature and cyclic loading.

System compatibility

MV terminals, cable boxes and LV bushings are matched to the switchgear and protection scheme.

Buyer questions

FAQ for 8000 kVA 35 kV Oil-Immersed Transformer Low Loss

What is 8000 kVA 35 kV Oil-Immersed Transformer Low Loss best used for?
This model is specified at 8,000 kVA and 35 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
What is the typical lead time for 8000 kVA 35 kV Oil-Immersed Transformer Low Loss?
Standard distribution units typically ship in 25-40 days after drawing approval. Large power transformers and integrated stations are scheduled by design review, core and winding production, tanking, testing and packing. The exact date is confirmed in the quotation.
Which standards and tests are supplied?
The transformer family is designed to GB 1094.1, GB/T 6451 and IEC 60076. Routine tests include winding resistance, ratio, impedance, no-load loss, load loss, insulation resistance and power-frequency withstand. Type and special tests are available on request.
Can the transformer be customised for 60 Hz or a hot climate?
Yes. Frequency, ambient temperature, altitude, enclosure, corrosion class and terminal arrangement are project inputs. The design is adjusted before production, and the approved datasheet becomes the inspection basis.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
