Principles of Cable Sizing :-

current carrying capacity, voltage drop, short circuit.
Cables are often the last component considered during system design even if in many situations cables are the true system’s lifeline: if a cable fails, the entire system may stop. Cable reliability is therefore extremely important, then a cable system should be engineered to last the life of the system in the installation environment for the required application. Environments in which cable systems are being used are often challenging, as extreme temperatures, chemicals, abrasion, and extensive flexing. These variables have a direct impact on the materials used for cable insulation and jacketing as well as the construction of the cable. Using a systematic approach will help ensure that designer select the best cable for the required application in the installation environment. This lessons will provide students main guidelines for perform this approach.

Thankyou bhaiya
I’m a working professional nd I’m really suffering alot in corporate world because no one is ready to tell me

[sourabhsharma]

Great vedio sir, I have'nt seen this type of content on this particular topic in which any industry can actually calculate their cable size and will no longer be dependent on assumptions.

[useer-eotn]

Ap bht acha prhate ho aisi videos bnate rhee... Respect from pakistan

[khaledshaikh]

Helpful videos for Industrial projects
Thank you

[SONUSAINI-lzqs]

This video is very important every electrical field.
Thank you sir.

[Jsr]

well done sir, from long time need for such a good explanation..I LIKED UR VDO

[Shailendra_singh_]

Thank you for the good information i think need to some more calculation like Derating Factor of Cable ?

[sayedmustaffa]

Ok Thank you for detail video
Kindly requesting to provide details for Multiple cables running in ground
Multiple cables running in air through cable tray

[mahidavilas]

Hi, thank you for this video. I have a quick question for you, instead of using 95sqmm size cable, can we route two run of 70sqmm cable or not??? Please tell me the reason. Once again thank you.

[sohampise]

Proper explanation ; thank you for such good video.

[kashmirengineeringvision]

this is very good but i have a small doubt let's consider the 80kw load is inductive so the starting current will be more don't we have to consider that in it ??

[shoaibahmed]

Superb bro u r awesome keep it up n thank u soo much ❤

[kavinraj]

Hi sir, fantastic explanation, kindly make video for current carrying capacity of particular armoured cables size(without knowing power), like 4 core 240 sqmm armoured cable.

[keyable]

Could you pls do videos also in English? So it will be accessible for much bigger audience. thnx

[whydoyouwannaknowmyname]

Correction : for voltage drop
It is( 1.732*I*R*L*100) / V3ph * NO.of Run * 1000

[MikkuVlog]

Dear Raman ji this is for aluminium cable or copper cable ? For both these same formula will be applicable or different if different formula then please tell

[abusalehAbir]

Very nice Sir . keep up the good work Sir :)

[vinodmenariya]

Sir it great please made single phase wire size selection

[rano.rajawat]

Sir could you please help me
our load ism1500kw so how many cables of 300mm aluminium would we need from transformer to load, cable length approximately 50m

[mwncc]

Sir sorry, I have question in cable sizing.
What is the meaning of no of runs?
Example:
5R/3.5C/240sqm/XLPE and
1R/3.5C/25sqm/XLPE
Thank you Sir
