Different coloured plastic can aid identification of individual wires.

The plastic coating can also prevent rust and prolong durability.

How does plastic over metal wires prevent being electrocuted?

Plastic is a bad conductor of electricity. Metals are good conductors of electricity. You get the metal wires coated by plastic. So when you touch the wire, you do not get the electric current. This nature of the plastic protects you from getting electrocuted.
