High and medium voltage transformers are complex electrical equipment for which the modern Plug and Play principle cannot be applied. The production time for one such unit starts from 6 months, as it includes many different stages, from manufacturing insulation from cardboard to creating diffusion copper-aluminum contact transitions.

Due to their design features and heavy weight, high-voltage power transformers require final assembly on-site.

Today's post is dedicated to the installation of a 35/6 kV 16 MVA power transformer for one of our customers.

The first stage is transportation to the installation site, unloading, and positioning. Since the transformer weighs 36 tons, all operations for lifting, lowering, and moving it are carried out using hydraulic jacks and pushers.

To prepare for such rigging work, a small railway needs to be installed at the required height. Only after this, the operator, using the control of the oil station, begins to slowly move the transformer to the installation location. This seemingly simple operation of unloading the transformer from the trailer takes a work shift for a team of 5 people.

This is just the beginning. So, to be continued...
