of years of service and capable of manufacturing good quality Transformers.
facilities required for manufacturing of good quality transformers are as
and Development Division
The Design and
Drawings Division is computerized and we are adopting the latest technology in
designing the transformers as per the Indian Standards and customers
documents for procurement of raw-materials, manufacturing activities, etc.,
will be issued from this department, in line with the requirement for
manufacture of Transformers as per the customer specification.
Control and Testing facilities
will monitor the various manufacturing activities, up to final testing of
transformers to ensure that the transformers coming out will conform to the
Indian standards and customers requirement. The various inspection procedures
adopted are as under:
- Inspection of Raw-Materials
received from various vendors.
- Inspection of Manufacturing
Process at various stages.
- Final Testing of the transformers
as per Indian Standards.
- Inspection at the dispatch area
before dispatch to ensure that the transformers are fitted with all
procedures and tests conducted are as per the Indian Standards which are quite
elaborative. This department is headed by qualified and experienced engineers
and is having a team of qualified personnel at various stages and they will be
independent from production department to ensure that the quality parameters
are complied with, at various stages of manufacture.
of good quality raw-materials
The major raw-materials
required for manufacture of good quality of transformers are as follows:
Steel Laminations - Cold Rolled Grain Oriented Steel.
are very important raw material, used in manufacture of transformers which
constitutes nearly 50% of the material cost. The quality of this material will
maintain the losses within the specified limits and also life expectancy of the
Grade Double Paper Covered Copper/Aluminium Conductors.
We are procuring
this material from various reputed suppliers, who can supply the conductors as
per our specification. The material received will be tested at our works, for
resistivity, insulation, tensile strength, etc, before they are put into use.
This material is
very important in the performance of the transformer particularly, longevity.
We are procuring the Oil conforming to latest IS 335 from reputed firms. Each
and every batch of Oil Tankers received at our works will be subject to sample
testing. We will conduct BDV resistivity and Tan Delta tests etc., before the
same is accepted. The Transformer oil will be once again subject to filtration,
before filling up into the transformer in hot condition. This ensures that any
moisture or impurities in the transformer is removed before filling into the
Materials like, Insulating Paper, Press Boards, Porcelain Insulators, Varnish,
Paper Tubes, Varnish & Paints etc.,
raw-materials are important items in the manufacture of Transformers. Any
defects will result in early failure of transformers. We are procuring these
materials from reputed firms and various other items like Porcelain Insulators,
Bushing Metal Parts will be procured from suppliers who can supply as per our
specifications. We will carry out required inspection and tests on these items
before they are used.
