Conductor and insulator is both of electrical insulator, such as copper and porcelain line post insulator we will talk about the conductor and insulator definition, in the other word, will tell you the theory of conductor and insulator.
Conductor definition:
In a conductor (usually metal) many of the electrons are free to move around within the conductor. Conductors are often referred to as having a "sea of electrons" since the movement of the electrons looks like a flowing sea.
As the positively charged rod is brought near the conductor, the electrons are attracted toward the charged rod. This causes a force of attraction to be created between the rod and the conductor. As the negatively charged rod is brought near the conductor, the electrons are repelled away from the charged rod. This causes a force of attraction to be created between the rod and the conductor. As a result, we can say that a charged object will always be attracted by a conductor. The porcelain line post insulators end fittings are made of a kind of Aluminum conductor.
Insulator definition:
In an insulator (such as ceramic pin post insulator) the electrons are not free to move around the entire object. They are generally restricted to moving only around the atom they are attached to. They can move from one side of the atom to the other but are unable to leave the atom. As a result, we say that charges stay where you put them on an insulator.
