BRIEF SUMMARY OF CIM SHOP (BLOCK – IV)
BAY-1: Bar winding shop: Manufacturing of stator winding bars of
generator, Micalastic Tank & Oven
 |
| Bars with coating |
BAY-3: Insulation detail shop: Manufacturing of hard insulation &
machining of hares insulation part (Glass textolite) such as packing, washer,
insulation box, wedges etc. & CNC Taping Machine
Bar Shop: This shop is meant for manufacturing of stator winding
coils of generator that may be turbo-generator or hydro-generator.
Why do we call it bar: It is quite difficult
(rather impossible) to manufacture, handle and wind the coil in stator slot of
generator of higher generation capacity because of its bigger size and heavy
weight. That is why we make coil in two parts. One part is Bottom part of coil called bottom or tower bar and
other part of coil is called top bar or upper bar.
TURBO-GENERATORS: The
manufacturing of bars of standard capacity such as: 100MW, 130MW, 150Mw,
210/235MW, 500MW
BAR SHOP
INTRODUCTION
1.
Block - 4 is basically divided into two parts:
a)
CIM – Coils and Insulation Manufacturing.
b)
ACM – Apparatus and Control Gear Manufacturing.
2.
CIM Block is designed to manufacture stator winding
bars of turbo and hydro generators and coils like DC armature coil, main pole
coil, equalizer coil etc.
3.
The Block consists of 3 Bays: Bay 1, Bay 2 and Bay 3.
For handling and transporting the various components, over head crane
facilities are available, whose capacities depend upon the products
manufactured in each bay. There is also a number of self propelled electricity
driven transfer trolleys for the inter-bay movements of components/assemblies.

available in bay 1.

There is a special room for insulation and curing of
all the stator bars in Bay– 3.
This shop is meant for manufacturing
of stator winding bars of generator that may be turbo generator or hydro
generator. It consists of various sections. In each one of these sections,
various processes of manufacturing the bar occurs independently. In the
conductor cutting section, there is a Roebel bar Manufacturing Centre, where
conductors are cut, bended and transposed. In the same section, crossover
insulation is applied on the bends manually. In the forming section, the bars
are given actual shape according to the design. The overhang portion is made. In
the brazing section, the contact sleeve and water box are brazed. Various tests
like Nitrogen leakage test, helium leakage test, thermal shock test etc. are
done in the testing section. In the Micalastic section, the bars are
impregnated with the resin. In the finishing section, the bars are finished
before being sent to Block1 for winding.
