Hello!
Electrical wires have a plastic covering since plastic is a bad conductor of electricity. It does not conducts heat properly and is easy to handle therefore.
Similarly the handles of a pressure cooker are
made of plastic since it is a bad conductor of heat. The pressure is cooker is made up of metal so that the food can be cooked but the handle is plastic which is necessary to hold it or use it easily.
