How to replace an AC adaptor plug

Hi all,
I have an ac adaptor with a broken internal wire (close to the end that goes into my laptop). I'd like to replace the wire and connector with a replacement. The replacement cable has two wires, which are unmarked and identical.

I cut the connector off the ac adaptor cable, ready to solder it to the replacement. But, the internal wires are different. There is a single copper wire, which has rubber shielding around it. Around the outside is a silver-coloured wire which is spread around the outside of the rubber shielding.

Can I just twist the silver wire into one thicker wire, and solder each of the two (copper and silver) to the wires of the replacement? Do I need to worry about orientation? There are no markings, but I don't want to fry my EeePC!

Thanks in advance,

Lee
