Three Phase Tranformer
Applicable Standards
IEC (International Electro technical Commission).
ANSI (American National Standard Institution).
BS (British Standards).
IS (Indian Standard).
Description
manufactures a wide range of distribution and power transformers ranging from 10 KVA to 5000 KVA.
These transformers
can be free breathing or hermetically sealed.
Conventional transformers are fitted with a
conservator with breather for free breathing while
hermetically sealed are without breathing with
bolted cover. 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 undesirable. Transformers
immersed in synthetic coolants are suitable for
use indoors, with adequate ventilation, or near to
the load centre where oil would not be considered
environmentally acceptable. The liquid filled
transformers can be supplied with cooling either
by corrugations on the side of the tank or Pressed
steel radiators mounted on tank body. Transformers
can be filled with either oil or one of several
low flammability synthetic fluids such as midel.
Both types can be supplied with HV and LV
Switchgear incorporated into substations.
can supply conventional/hermetically sealed/bolted
type, indoor/outdoor type, pole/platform mounted 3
phase, 50/60 Hz, oil immersed, ONAN/ONAF/ OFWF
cooled, step up/step down, double wound with Al/Cu
conductor, Continuous duty transformers from 5 KVA
to 20 MVA upto 33 KV Class with ‘A’ Class
Insulation and designed to withstand Short
Circuit, & Impulse Test in accordance to IEC /
BS / ANSI / IS / NEEMA.
Standard Transformers
In order to meet the growing demand of transformers
with short deliveries, have developed a
separate production system called ( Standard Transformers). This range of are
manufactured with standard losses and in
accordance to IS : 2026 latest. can supply a
comprehensive range as depicted below in short
delivery periods. The second of our production
system known as Repeat transformer enables
us to reproduce any of our previous transformer
designs again in the shortest time with the object
of keeping delivery time to a minimum. Details of
Characteristics & dimensions of standard
transformers with standard fittings manufactured
in accordance with IS : 2026 latest., and can be
delivered in short delivery period upon order
confirmation.
Specification for ( Standard Transformer)
