Transformer Manufacturing Process

2015 Article

The main process line of the Virdi’s HT transformers is:

Core: The core is made with laminated and low loss electrical steel sheets that is imported, grain oriented, cold rolled and sheets of high grade steel. The cores are assembled in
a manner that they reduces the noise caused by vibration;
individual stamping are coated with insulation varnish which
is resistant to heat and oil on both sides. The core is connected
to the clamp which ensures that it is effectually earthed. The
core legs are bounded with heavy duty insulating tape. The
yokes are rigidly and securely clamped between the folded
steel channels. Clamps on top and bottom are firmly attached
to each other by the means of tie rods. Tie rods serves the
dual purpose of transferring the load from the bottom to the
top clamps and securing the winding in place. This prevents
tensile stress being setup in the core legs, which could
adversely affect the iron losses.

Winding: Transformer windings also known as ‘Coils’ are precisely designed to meet three basic requirements: thermal, mechanical and electrical. These windings wound concentrically and are cylinder shaped. Both HV and LV type windings are wound with adequate securing and brazing
tapes in order to get a sturdy, robust and self-supporting structure.

Winding Connections: Tapping and phase leads run in paper covered conductors. Adequate barriers are used to separate the phase leads from the tapping. Rigidly brazed tubes are used to maintain the required clearance from coil to tank.

Advanced Machining Processes of Metallic Materials: Theory, Modelling and Applications - Wit Grzesik - Book Information

Advanced Machining Processes of Metallic Materials: Theory, Modelling and Applications


Wit Grzesik
Elsevier, Jan 22, 2008 - 472 pages


This book updates our knowledge on the metal cutting processes in relation to theory and industrial practice. In particular, many topics reflect recent developments, e.g. modern tool materials, computational machining, computer simulation of various process phenomena, chip control, monitoring of the cutting state, progressive and hybrid machining operations, and generation and modelling of surface integrity.
This book addresses the present state and future development of machining technologies. It provides a comprehensive description of metal cutting theory, experimental and modelling techniques along with basic machining processes and their effective use in a wide range of manufacturing applications. Topics covered include fundamental physical phenomena and methods for their evaluation, available technology of machining processes for specific classes of materials and surface integrity. The book also provides strategies for optimalization techniques and assessment of machinability. Moreover, it describes topics not currently covered in other sources, such as high performance and multitasking (complete) machining with a high potential for increasing productivity, and virtual and e-machining.
The research covered here has contributed to a more generalized vision of machining technology, including not only traditional manufacturing tasks but also new potential (emerging) applications such as micro- and nanotechnology.

- Many practical examples of modern machining technology
- Applicable for various technical, engineering and scientific levels
- Collects together 20 years of research in the field and related technical information

Fundamentals of Machining Processes: Conventional and Nonconventional Processes, Second Edition - Hassan Abdel-Gawad El-Hofy - Book Information

Fundamentals of Machining Processes: Conventional and Nonconventional Processes, Second Edition
Hassan Abdel-Gawad El-Hofy
CRC Press, Aug 6, 2013 - 562 pages

Completely revised and updated, this second edition of Fundamentals of Machining Processes: Conventional and Nonconventional Processes covers the fundamentals machining by cutting, abrasion, erosion, and combined processes. The new edition has been expanded with two additional chapters covering the concept of machinability and the roadmap for selecting machining processes that meet required design specification.

See What’s New in the Second Edition:

Explanation of the definition of the relative machinability index and how the machinability is judged
Important factors affecting the machinability ratings

Machinability ratings of common engineering materials by conventional and nonconventional methods.

Factors to be considered when selecting a machining process that meets the design specifications, including part features, materials, product accuracy, surface texture, surface integrity, cost, environmental impacts, and the process and the machine selected capabilities

Introduction to new Magnetic Field Assisted Finishing Processes


The book is written by an expert with 37 years of experience in research and teaching machining and related topics. The book covers machining processes that range from basic conventional metal cutting, abrasive machining to the most advanced nonconventional and micromachining processes. The author presents the principles and theories of material removal and applications for conventional and nonconventional machining processes, discusses the role of machining variables in the technological characteristics of each process, and provides treatment of current technologies in high speed machining and micromachining.
