Distribution Transformers
TESLA manufactures a wide range of distribution
transformers ranging from 25 KVA to 5000 KVA with all voltage
class and upto 33 KV.These transformers can be free breathing,
fitted with a conservator or hermetically sealed. The liquid
filled range can be cooled by either tank - mounted plate
radiators or by corrugations on the side of their tanks. The
latter being known as conventional type transformer.Free breathing
units, with or without conservator are normally oil-filled,
while hermetically sealed transformers can be filled with
either oil or one of several low flammability synthetic fluids.
Both types can be supplied with HV and LV Switchgear and incorporated
into substations.
Hermetically sealed transformers are totally maintenance free
and are particularly suited for use in exposed outdoor environments
such as moisture, salt or dust laden atmospheres. They are
used extensively in chemical plants, oil and gas terminals
where poor accessibility makes regular maintenance impracticable.
Transformers immersed in synthetic coolants are suitable for
use indoors with adequate ventilation or near to the load
center where oil would not be considered environmentally acceptable.
