5. SIMPLE STRCTURE OF
TRANSMISSION TOWER
Peak of transmission tower
Arm
The portion above the top cross
arm is called peak of transmission
tower. Generally earth shield wire
connected to the tip of this peak.
Cross Arm of transmission
tower
Cross arms of transmission
tower hold the transmission
conductor.
Cage of transmission tower
The portion between tower
body and peak is known as cage
of transmission tower. This
portion of the tower holds the
cross arms
Damper
Foundation

7. Pre Production Department
1. Understanding the drawings made in Mumbai
Design Department of KEC.
2. Making 2d drawings of each particular part in
Auto-Cad with full dimension.
3. Teaching labors about the drawings.
After making one sample model comparing that
model with given design.
5. Than calculating the errors and making again
an error free drawing.
6. Then again helping the labors in understanding
the new Drawing and making the final model..

9. Production Procedure
• Straightening
When angles are imported they are not fully straight
according to requirement . For that purpose roller
straightening machine is used.

10. Bending
Bending is a manufacturing process that produces a V-shape,
U-shape, or channel shape along a straight axis in ductile
materials
KEC use Hot Bending Machine, which bend the angles by
heat treatment process.
Here angles are heated
for 30 to 35 minutes and
than hydraulic pressure
is applied to bend

11. Punching, cutting & stamping
• Punching :The main function of punching is to holes on angles at
various distance which have thickness up to 12mm.This
m/c is based on hydraulic pressure principle.
• Cutting :Cutting is the separation of a physical object, or a
portion of a physical object, into two portions, through
the application of an acutely directed force.

12. • Stamping:A stamp is a distinctive mark or impression made
upon an object, a device used to make it,
or a distinctive sticker applied to an object
CNC machines are used to complete all
these processes

13. Notching
• Notching is a metal-cutting process, small cuts are
made on the flanges of angle at any angle.

14. Drilling
The angles which have their thickness above 12mm are
drilled. For this purpose there are six radial arm drilling
machines. These machines are rounded at 360’. The
machine is operated manually.

15. Galvanization
• Galvanization is the process of applying a protective zinc coating to
metal, in order to prevent rusting and corrosion.
• Mainly there are two methods of Galvanizing :
1. Dry galvanizing
2. Wet galvanizing
The life time of wet galvanizing more then dry galvanizing so KEC uses
wet galvanizing.
• Procedure of galvanizing :- Galvanizing is completed in different
steps. The process is following in different tanks.

16. Prepration for galvanizing

17. Degreasing Tank:-
Caustic solution presents in this tank for
removing oil, grease, dust etc. on the material. Material is dipped
about half an hour at 30-35’c temp.

18. Acid Pickling Tank:-
The material is dipped into HCL tank for
removing rust, oxides, dust, oil etc. This process takes time about
40-45 min.

19. • Rinsing Tank:The material is cleaned and cooled by dipping it in
water tank because HCL acid sticks on it.

20. • Pre-Fluxing tank:A light coating of ZINC-CHLORIDE &
AMMONIUM-CHLORID is made on material. There are 60:40
ratio of zinc & ammonium chloride. It is used for preventing
spotting during coating of ZINC in Zinc bath

21. • ZINK BATH:-
There is mainly ZN in this bath at 460’c
temperature. AL & Lead also present these for surface
finishing of material. The material is dipped into it and after
certain time it is raised from it. Thus the Zn coating is made.

22. • RINSING TANK:-
This tank consists water. The material is dipped
into it for cooling , cleaning after Zn coating.

23. Galvanizing procedure:-

24. After galvanizing and all production procedure,
the product was sent either to
Quality department –
In case of when angles are made first time for customer requirement ,
than
sampling is necessary. So the quality department assembles the
manufactured
tower if it founds any error it reports to preproduction department.
Or to
Loading Department
In case when quality department is ok with angles, they directly go for
loading, than they dispatched to their desired location.
