OMEK Power 33kV transformers are manufactured in compliance with IEC, ISO and ASTA standards, and hold CE certification.
Scope of Supply
OMEK Power manufactures 33kV transformers from 50kVA to 10,000kVA.
We have exported 33kV transformers of 2500kVA to commercial infrastructure projects in Kazakhstan, and 33/415V transformers of 1000kVA for small business parks.
OMEK Power manufactures custom 33kV transformers. Depending on your local grid standards and project requirements, it can be designed to step down voltages below for medium voltage distribution networks.

Packing and Delivery
For oil transformers, we usually use iron pallets for packaging. If the height of a single unit is less than 1.2 meters, we will make two layers of iron racks.
The specifications for container loading are usually calculated after the price is released (when the price is released, there will be a basic size and weight), and then the container loading is determined based on the size and weight.
