OneMoreFarang Posted May 20, 2022 Share Posted May 20, 2022 (edited) I like to buy some stranded and full copper (is that the correct term?) cables to use indoors in my new condominium. I want 3x1.5sqmm 3x2.5sqmm 3x4.0sqmm. What are the official (Thai) names for these cables and what is a good (online) source for good quality with a reasonable price. It seems many places sell a lot of cables with just 2 wires without earth. I don't like that. I want these two types. Thank Edited May 20, 2022 by OneMoreFarang Link to comment Share on other sites More sharing options...

It seems many places sell a lot of cables with just 2 wires without earth. I don't like that. What you should look for is often not 3x1.5mm but 2x1.5mm with ground here are a couple of examples from Bangkok cable https://www.bangkokcable.com/assets/img/pdf/BCC_E-Book_PriceList.pdf as you can see the colour on the cables is different for 3x1.5mm and 2x1.5mm with ground, though naturally the cores are no different. your second example is VAF-G the second that you want is VCT-G here is the VCT so the colours don’t include a green/green yellow the cost for VCT & VCT-G is exactly the same if the number of cores is the same as in 3 x 1.5 VCT & 2 x 1.5 VCT-G as both have 3 cores Edited May 20, 2022 by sometimewoodworker 5 Link to comment Share on other sites More sharing options...

Naturally the insulation colour is only important to some users, and not all variants have cable availability in cut lengths.

KhunBENQ Posted May 20, 2022 Share Posted May 20, 2022 (edited) Stranded cable is สายไฟไวนิล (săai fai wai nin). WiKi is a bit more accurate and uses สายไฟฟ้า (săai fai fáa) for electrical cable. Edited May 20, 2022 by KhunBENQ Link to comment Share on other sites More sharing options...

Crossy Posted May 21, 2022 Share Posted May 21, 2022 I think there's some confusion in terminology here. "Single core" means one conductor in the insulation, that conductor may be solid or stranded. Stranded is easier to work particularly in the larger sizes. This would be "THW" and is intended to be contained in conduit or trunking. There's also a flexible stranded (more, finer strands) which is much less of a wrestle in the confines of your boxes. This is "THW-F" and is again intended to go in conduit. If you want several cores in one jacket then you're looking at the "flat" cables, VAF and VAF-G (which has a ground core). VAF can have either solid or stranded conductors but not the really fine flexible strands. 1 Link to comment Share on other sites More sharing options...

Orange conduit = OK Direct in the render = I wouldn't, but the Thai Zazaki spec. for VAF-G says "VAF-G Electrical wire is a building wiring for surface or above ceiling wiring or direct embedded in plaster." https://www.sk-wires.com/en/vaf-g-building-wiring-flat-type-thai-yazaki/ Link to comment Share on other sites More sharing options...

I think you've answered your own question - "good quality products". And, they are rather difficult to get off should you need to. Also, as @SomchaiDIY notes they don't work well with the fine multi-strand. Oddly enough I DO like Wago connectors (the genuine ones) over those awful wire-nut things. But, of course, it's entirely up to you what you do ???? Link to comment Share on other sites More sharing options...

Personally if it is important then I only use quality products.

Bootlace ferrule we call this in english verbal Invent to contain cable strand and stop spread when connection made on clamp terminal Most use in build of control panel system Maybe idea for fine strand cable in screwless connection but I think better if soft ferrule under pressure from screw terminal clamp 1 Link to comment Share on other sites More sharing options...
Crossy Posted May 21, 2022 Share Posted May 21, 2022 I wouldn't use ferrules on the screwless connections, but I don't like them anyway. Ferrules MUST be properly crimped, no crushing it with pliers! 1 Link to comment Share on other sites More sharing options...

I just got some Hako receptacles and didn't know they were the push type until I opened. But, the wire just needs to be pushed in until it can't be tugged out. A flat blade screwdriver into the release and they easily pull out. So there. ???? 2 Link to comment Share on other sites More sharing options...

FriendlyFarang Posted May 21, 2022 Share Posted May 21, 2022 Solid wires for all fixed installations, like cables in walls Stranded wires if the cable will be flexed If you use stranded cables for wall installations you will run into problems because it doesn't work well with all connectors that you find in light switches, plugs, breakers etc. 1 Link to comment Share on other sites More sharing options...
Yellowtail Posted May 23, 2022 Share Posted May 23, 2022 I know stranded is much easier to pull through conduit. Fire-rated sometimes has a coating that also makes it easier to pull. The solid-core stuff is a nightmare to pull. Is the fine stranded stuff pretty much just for cords and moving assemblies and whatnot? If I had stranded wire I needed to push in I would just tin the ends.... Link to comment Share on other sites More sharing options...

If it is hard to pull (I push) then your conduit is too small or you're not using single wires. Just sayin. Link to comment Share on other sites More sharing options...
