3 Core x 35 Sqmm Cable (How we measure 35Sqmm)
Answers were Sorted based on User's Feedback
Answer / anas
Eg3C x 35SQMM
Each core is 35SQMM (Core Red , Yellow , Blue)
To measure the conductor SQMM as per below
From BS 6360 Show that : 7/2.52mm
7/2.52mm is per below ;
Single wire diameter : 2.52mm (Based on BS 6360)
Number of Strand : 7wires (Each wire is 2.52mm)
Calculation
=(2.52mm)(2.52mm) x PI()/4 x Number of Wire (7)
= 34.9131 approximate 35SQMM

Answer / p. h. godavary
Cable size (area of each core) is normally specified in square millimeters
(sq. mm). In this case it is 35 sq. mm. The cable size is always printed / marked on the cable itself by the manufacturer.
The conductor in each core of power cables is normally made of multi strand circular wires (Copper / Aluminum ).
To measure the size/area of the conductor, measure the diameter of a strand in a core and calculate its area. Multiply this area by number of strands in a core.
If the diameter of a strand in mm is D,
then its Area = [∏/4] [ DxD ] = [3.14/4 ] [DxD] Sq. mm.
Size of the cable (or) Cross sectional Area of a Core
= [Area of a strand x No. of strands in the core].

In my answer (Answer #2), I have used the Phi symbol in the 'Area Formula'. But I find the same is appearing scrambled.

Answer / ali
you are measure the one conductor size 35 sqmm cable in
micro meter than you give a size in squre and multiple by
pae multiple by number of conductor dividing by number of
core,you are give the any cable size.
for example. i measure the 4 core * 300 sqmm cable size
(2.5)squre x pae x 61 /dividing by number of core 4
you have size the cable

( Re: WHAT SHOULD BE THE RATING OF MCCB FOR 415V,3Ph,50KVAR CAPACITOR BANK Answer # 1 The capacitor current would be kvar x 1000 / (415 x sqrt3). This would be 70a approx. The MCCB selected should have *atleast 1.4 times this current i.e. 1.4 x 70= 98. So you should choose at least 100 A mccb.) regarding to this answer,i would like to know why the current have to times 1.4 to get the right amphere for the mccb.hows the formula to get the 1.4??tq
