My company's business is stretching and armouring cars. In the former process we must also lengthen all the wires. We've just come across aluminium cables, which pose a problem — until now we used to cut and solder the cables together with the extension.
The sections we have to deal with are (in mm²):
I'd like to know what [industrial] options are available to stretch aluminium cables. There is one possibility that is out of question: replacing entire cables with longer ones. We don't have all the connectors since not every single of them is available, some are proprietary and brand-specific. So we're left with actually "stretch" the cables.
So what are the available options?
