Background
 
For 220/400 KV line, 
ACSR Zebra (Ø 28.62 mm) and
ACSR Moose (Ø 31.77 mm) conductors are been used
having current carrying capacity of 1000 Amps each
 
Increase in demand for Electrical Power Generation &
Transmission, there exist a few hindrances
 
High cost 
to install new Power lines
 
Difficulty in acquiring Tower sites 
– Right of way
(ROW)
 
Large time 
involved in constructing new Power lines
Therefore, 
High Temperature Low Sag (HTLS)
conductors, having high ampacity, which can deliver
large power without any change in existing tower
design are been used.
 
Hence there is need to design connector for HTLS
conductor having permissible temperature as per IS
5561

Problem Definition
 
Design of the connector should be such that the 
maximum allowed temperature
should be less than 85⁰C 
including the ambient temperature 
at 1600 A 
as per
standard IS 5561.
 
Moreover, the connectors that are being used for HTLS cables should be made up
of IS 5561 (AL - 4600 & A6 grade) or equivalent grade of aluminium as per standard
IS 617.
 
Need for FEA
 
Helps to 
study response of the system based on loading condition 
in real world
situation
To 
determine the correctness and efficiency 
of a design before the system is
actually constructed
Reduces lead time and cost 
to product

Conclusion
 
Multiple iterations were carried out in designing of T- Connector based on
simulation results in order to increase optimum surface area of connector.
 
Current requirement was high, hence heat sink were incorporated along with the
connector to reduce the temperature rise as shown below.
 
 
 
 
 
 
Fast heat dissipation and high mechanical strength of the heat sink played a
decisive factor in reducing the maximum temperature of the T-connector.
 
 
 
 
Future Work
 
Prototyping, Real life testing & Validation needs to be done.

This project involves the simulation of temperature rise in electric power connectors used for high ampacity HTLS conductors, aiming to ensure the maximum temperature remains below 85°C as per standard IS 5561. The study includes the design requirements, material properties, FEA analysis, and simulation results with and without a heatsink in the conduction path.
