Product Q&A

Q:What is the efficiency rating of the 22 KV /35 KV step-up transformer?

Our transformers are engineered with high-grade silicon steel cores and optimized copper/aluminum windings, achieving a peak efficiency of up to 99%. They feature ultra-low no-load and load losses, complying strictly with the latest IEC eco-design standards to maximize your PV plant's ROI.

Q:What does "Prefabricated" mean for our project timeline?

It means the transformer, MV switchgear, LV panels, and auxiliary systems are $100\%$ pre-assembled, wired, and factory-tested before shipment. Once it arrives at your site, it only requires foundation placement, external cable connections, and final commissioning. This reduces on-site civil work and installation time by up to 70%.

Q:What factory tests are performed before shipment?

Every single unit undergoes rigorous factory acceptance testing (FAT) before dispatch, including routine tests for transformer insulation, voltage ratio, winding resistance, dielectric tests, and functional simulation of all switchgears and protection loops. A comprehensive test report is provided with the delivery.
