How to make a cable

We’ve talked a bit about cable splicing in the past, but never focused much on the process of actually making a cable. Today we resolve that.

Here is a short video (albeit in French) that demonstrates how small steel cables are wound together to create medium-sized cables, which are then spun again with other medium-sized cables to create the final super cable — the same one used in cable propelled transit systems.

I think the shear magnitude of the machines involved in this process is impressive. So is the final 5m diameter spool, which weighed in at around 150 tons!

Also, I find it reassuring that there are tests conducted all through out the process that test for strength and consistency, and that these are done both manually and with lasers.

It would be interesting to know about how long it takes to make one spool of cable.
