I don't see how 0.16mm diameter strands can have the strength to withstand cable pulling. Maybe this type don't get pulled over long distances.

We usually use 7 strands cables with minimum 1.5 mm sq for power.

Is there zinc cable? I know of copper and aluminum.

Those are substandard size.. not even 1.5mm² for light circuit.. u can google the sizing
hence they are only used as device cord NOT permanent installation (which is the usual 1.5, 2.5, 4.0 kind of sizing)

They make horrible device cords if ur stripping using pliers (not a jig) as its too easy to cut thru the hair thin metal (if u wired LED lights u will know how annoyingly smol)

In offshore projects, minimum power cable size is 2.5 mm sq though.

7 strands are due to withstanding termination crimping stress

Yes, 40 strands are not suitable for insulation wire strippers.

Unless you are building another webb telescope, why need to be so particular about the wire spec. In Msia we use cross sectional area 1.5mm2, 2.5mm2 for wire size.

got, my ups use big fat zinc cable, connecting the battery.

Frankly this is obsolete standard from British era
Now no one in the world use anymore

I always use 70/76 standard.

There is only 2 type of material commonly used for cable construction, copper and aluminium. Zinc is just the coating.

oh then i might be wrong, saw the material, then do some google, found zinc, i tot its zinc.

I see! But we consumer, hard to differentiate, right?

What does SIGNAL means. For example?

Ya lo. When I asked options or suggestions from the store, they only mentions 1.5mm or 2.5mm. and most probably go for 2.5mm!

signal means data, like network cable, the cable that connect from switch to your autogate(send signal to open / close gate), ignore POE in this example.

signal need very small amount of current, all it need to do is giving signal, not do work

Go for mega cable for the best quality....

Usually there are 3 sizes...

1.5mm
2.5mm
4mm

Depend on your load... But imma recommend 2.5mm and 4mm

Yup, my power extension also made from 2.5mmsq
Whatever I plug in to it will be comfortably cool

It becomes a technicality that insurance can and will use to deny claim if you use substandard cable in permanent installation.
Weakest point is the ceiling for max current capacity of any cable.

Still got sell on spee. Its alright for low voltage battery experiments for school but certainly not for point wiring (permanent installation)

Even power strips also use 1.25mmsq as minimum standard in SG.

For small cable/wire size < 6mm2, the manufacturer is more important. Some wire imported from China, the insulation will become brittle after few years, esp when exposed to UV. Pose a big risk for fire and electrocution.

Is the conductor insulated or metal coated?

I see! So, switch for lamps/lights consider Signal Cable?

Mega Cable means the Brand? If that's the name, a lot of people recommended Fajar Cable.

You always provided very Pro & Useful informations! Learned something 😁
Does it mean, no matter what's the purpose for, you'll always go for 2.5mm?

haha go for mega cable brand sir for best quality

That depends on what u installing, if concealed in-wall circuits carrying 230V must follow 1.5mm min
its super cheap even if u buy loose cut per meter
don't even bother getting anything thinner because hard to strip

if its those extra low voltage purposes like HDMI/ LAN cable then its not really a problem on cable thickness since those are only for data signal

2.5mm so peace of mind as this is way overspec, its the same stuff as in-wall so this extension can use macam a wall socket (use kettle or vacuum or rotohammers). Its heavy, and expensive, nobody will use 2.5mm except me
1.25mm SG standard for power strips because that CCA > 13A so anyhow fuse will blow before wire catch fire
Using lousy wire for power strips just mean that the wire will overheat before 13A fuse blow

all those 40/0076 70/0076 are substandard cable spec. good for kids to play with science experiments to light up 12V car bulb je

How abou wallt socket for Electric Stove (2500-3500w) ... Oven... Microwave? 2.5mm cable or 1.5mm is good enough?
