First of all, there is also copper conductor in it. But the most important is, I think, you are mistaking voltage and current. Resistance will limit current, but it will do nothing to voltage (except for fast transients depending on capacitive properties of the line -- sorry, there must always be some exceptions to every rule). 1M volts put to a conductor will still be 1M volts regardless of wether the conductor is 1ohm or 1M ohm. Remember, electronics is mostly fried by voltage, not by current. For high current to damage electronics at nominal voltage it must have an internal fault -- short circuit, for example, that causes it to draw more power than necessary. High potential, on the other hand, causes electrons to go all sorts of ways they are not supposed to go, causing damage to all sorts of things that are not supposed to be penetrated by electrons. You can damage sensitive electronics by waving your hand over it. You don't even have to touch it -- just the fact that you are moving some electrons on your hand causes electromagnetic field (moving charge == electromagnetic field) that causes potential to be induced in internal electronics (conductor in changing electromagnetic field == induction). Just read about why exactly electronics is distributed in those funny metalized bags.
