Hi,
Did you notice that a lot of Shopee or Lazada sellers selling Flexi Cable with description as below : 40/0076 (3C) = 1mm ?

In fact, 40/0076 is only 0.18mm, it doesn't meet 1mm specification.

And I only see Fajar Cable mentioned 32/020, which is 1.005mm.

So, an I wrong or misunderstood?

How about you calculate if the 0076 is in inches?

Wow... It's 1mm +

So, it shouldn't in mm but inch? This is a standard unit/calculation?

But Fajar Cable 020 in mm, right?

Confusing

make sure is sirim compliance :X

Ya lo! But those platform, they don't mention too much information 😞

You mean it was written 1mm 1.5mm instead?

My curious is, it was written 1mm but bracket with 40/0076! As mentioned from the reply above, if it's "inch", then 40/0076 meet 1mm specification!

But I saw some written 1mm (40/0076) , some said 1mm (40/076), this is headache!

Hi, I'll guide you thru the calculation.
40/0.0076 Flexible cable means 40 strands of 0.0076inch diameter wire strand. So 40 strands of 0.0076inch diameter = 0.19304mm diameter = 0.029267424mm.sq times 40 strand = 1.1706969596mm.sq cross section area. So it's actually more than 1mm.sq.

china made usually no la, unless you buy locally imported one :X

Thanks! Wow .. you are pro man!
Another struggle is, some said 0076, some 076! So? Isn't the same diameter, right?

Thats a pretty common typo in the industry. It should be 0.0076".

most useful reply ever....

Ya lo. But local seller supposed to provide those informations.


Alamak! So, do you think it's ok to purchase those no brand cable (as long as it's fully copper)?

I more than agree 💯👍

up to you la, not my money.

So, regarding to the Diameter, should always in Inch unit?

The cable size is actually nominal only for naming purposes. Usually it will be larger than the specified name. This is because there's many different grades of copper, a low grade one will have more resistance which gives more heat and will melt the insulation.

As per IEC 60228 and MS2112 cable size is defined by The maximum permissible resistance per unit length (in ohms per kilometre – Ω/km) of each conductor size, class and type

https://en.m.wikipedia.org/wiki/IEC_60228

To make things simple, just make sure ada sirim

For this kind, yes inch are used. Other common size are 70/0076 and 110/0076.
If you want to keep it simple, Fajar and UMS does have cable marked with the mm.sq cross section. They come in two type, Grey PVC Sheath and Black TRS Rubber (heavy duty) commonly used as outdoor extension cord.

The first question you should ask yourself is whether you value your life. If yes, look for SIRIM certified product.
