Electricity such an essential energy that it's hard to find where it's not needed.
The degree of inconvenience is seriously felt even during a short power outage.
It's no exaggeration to say that most products around us, such as mobile devices, home appliances, and sound devices run on electricity.
They are different in form, but they have one common feature: the products connect to electricity via wire.
Even wireless devices require a plug with wires to charge them.
The wire delivers electricity to the product, and for safety, they are covered with insulation so that electricity does not flow out of the wire.
The material used in such insulation is PVC, which adds a small amount of plasticizer to add elasticity and flexibility,
allowing the wires to bend. This makes wires convenient to use and store.
