C-H,
For some strange reason I can't get them links to work.

Have you tried again Mike? They're working for me.

Interesting reading there.

Hmm,
I tried again but, still no joy. [Linked Image]
Could have something to do with this Firefox browser I'm using.
It just times out when trying to open the links.

Using Firefox 1.0.7 (German) and it works fine?

Well,
Having Firefox 1.0.7 here, all I get is:
"www.topcable.com could not be found, please check the address and try again later".
I haven't got IE anymore to see if that works with the site in question.
Linux still rules though!. [Linked Image]

Firefox working ok here; original version 0.9, though the first time I tried a few days ago it did say not found. What if you try pinging the URL?

Hmm,
Not sure what caused that to happen, but thanks to Chipmunk (Cheers mate! [Linked Image]) who sent me a link to the site, I've had a look at the virtual tour of the manufacturing process.
I had the opportunity to take part in a factory tour of the old MM Cables in Christchurch back in 1998 and watching cables being manufactured is an amazing process to witness.
Most interesting bit I saw was the PVC insulation being "sprayed" onto the bare copper wires, seemed strange watching bare copper goes into one end of a small machine and it comes red.
Not sure how they do the Green/Yellow striped earth wires though.

Ohhhh, now you ruined next nights sleep for me, Mike. [Linked Image]

C-H,
It wouldn't be that difficult.
All you'd need is 4-6 bins spraying the PVC on with alternate colours in each bin.
They are in length-wise stripes here, not around the circumference of the wire.

Ditto here on all modern cables. When the European green/yellow earth was first adopted here there were some which used a kind of spiral wrap of tracer color, but now they're all longitudinal.

I think the specs call for the proportions to be no greater than 70/30, although I've seen some cheap flexes and cables where it seems to be almost completely yellow with just a very thin green stripe. [Linked Image]

On all of them though, yellow is now the predominant color.
