Height of gallery Mtr 2.40 1.756.5 Conclusion:
From the above, it is highlighted that every method of cable Laying has some
advantage and some disadvantage over each other. Hence it is proposed to opt
the best out of two system using good features of each one. The mixed layout
should be followed in cement plant in following manner due to its distinguish
advantages:
a) The main cable routing should be through Overhead cable gallery form MRSS
to all load centre. These cable routes do not have branches and sub branches
in between which results to shorter cable route length.
b) This main cable route will not create any hurdle in crane movement, material
shifting, structure erection etc. The electrical erection and cable Laying work
can be possible side by side between sub-stations which will helpful in completion
of various activities like interfacing between sub stations, charging of HT, LT
