A liquid can only conduct electricity if it has free ions because ions are the charge carriers there, there are no free electrons in water. However, because of the polar nature of the water molecule (moving into the realm of chemistry here), adding an acid or a base forms the ions required for conduction (H3O+ …

WebHistorically, glass insulators like Hemingray42 were used on the power lines and telegraph lines to prevent wires from getting in contact with wet poles. They were also employed to build the communication network and prevent current loss during transmission. A lightning arrester is a device, essentially an air gap between an electric wire and ground, used on electric power systems and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal.
