Question
3 Core x 35 Sqmm Cable (How we measure 35Sqmm)
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
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].

Answer
# 2
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
# 3
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

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

Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?   2
