Answer / mohammed hassan

the field is cocentrate at the sharp edge of square or
rectangular so the insulation is breakdown at this edge but
at circular the field is regular distributed

Answer / ak samy

The cables are mainly used for A.C tramission of power.As
per the SKIN effect law principle the ac current density
is concentrated on outer surfaces of the conductor with
flux distribution of concentric circles.Hence circular
cables are used an advanatge of current carrying capacity
point of view.For DC transmission the cables can be square
(or) Rectangular. It is immaterial.

Answer / kj

There are a number of reasons but I think the main 2 are
easier to make and more flexible.

I have seen multi core aluminium cables where the
conductors were formed into segments of a circle to fit
together into a smaller area.

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
