Finished 5 MVA 33/11KV Transformer
The transformer was painted to gray color (RAL 7035) as customer requirements.
Transformer in the Container
We dismantled the plate type radiators, oil conservators and other accessories and packed them in ply wood boxes, the transformer main body was nude. They are loaded in a 20 feet container.
Installation of Transformers
A power transformer is the second most costly equipment installed in power system. Hence, special care to be taken during installation of a new power transformer in an electrical substation. During accessing the interior of a power transformer, the worker should empty their pockets of all loose articles so that there would not be any risk of falling anything inside the transformer from their pocket.
The tools used during the work, should be securely tied with cotton tap so that they can be recovered if accidentally fall into the transformer interior. Jute should not be used as cleaning materials for a transformer. Loose fibers of the jute may be remained even after completing the cleaning work, which may affect the insulating properties of the equipment in future. Cleaning should be done by clean cotton cloth without any suspended loose fibers. Generally, many parts of a power transformer are transported from manufacturers separately.
