Use our quote form, WhatsApp or email. Rating, voltage, quantity, destination port.
We typically reply within 24 hours with price, technical data, applicable test reports and lead time.
Transformers 3–5 weeks; generator sets up to 1,000 kW 4–6 weeks, 1,500 kW 8–10 weeks after deposit. Tests shown by live video on larger orders, by report and video on smaller ones, or witnessed by your inspector.
You review the test report, photos and video, pay the balance, and we ship to your port.
Every order has one sales contract with our company, stating the specification, test scope, acceptance criteria, lead time, payment schedule and a 12-month warranty. If something is wrong, you deal with us, and we deal with the factory.
We are an export company, not a factory. Transformers, switchgear and generator sets are built by different specialist manufacturers. We bring them into one order and take responsibility for it.
Transformer, switchgear, panels and generator sets on one sales contract, one invoice and one shipment to your port.
We match each item to a manufacturer whose type test reports cover that design, and tell you which reports apply before you order.
You see the test report, photos and video of your own unit and pay the balance only after that. Your own inspector is welcome.
The 12-month warranty is in our contract. If something goes wrong you contact us, and we deal with the factory.
