Starting with a pre shipment photo: a 1500kVA transformer is heading to Kenya

These tangible details matter far more than any promotional claims.

I took a photo in the production workshop this morning – a 1500kVA oil-immersed transformer has completed all manufacturing processes and is now waiting for final packing.

About this transformer
The customer ordered a 1500kVA, 11/0.4kV oil-immersed distribution transformer. At this capacity, it's not a small unit – the total weight of the active part is close to 4 tonnes. It features all-copper windings, and the insulation system has been adapted for tropical climates. The voltage regulation range is ±2×2.5% (five taps), which is sufficient to cover most grid fluctuations.

Testing phase
On the day of factory testing, the customer did not send a representative on-site, but asked us to record the entire process on video.

We went through all the tests – turns ratio, losses, no-load current, impedance voltage, power-frequency withstand voltage, induced overvoltage withstand test, and more. All data fell within the design and standard requirements. The test reports, together with the video, were sent to the customer, and we received their confirmation reply the very next day.

What we need to do
What overseas customers value most is often not the price, but certainty.

When will it be delivered? What are the actual test data? Is the packaging suitable for long-distance ocean freight? Will there be any unexpected issues during installation? These tangible details matter far more than any promotional claims.

From design to shipment – drawing approval, material procurement, manufacturing, in-process inspection, factory testing, packing and loading – every step carries potential risks. What we need to do is to identify and resolve these issues before the customer even notices them.
