The emergence of insulators

The emergence of insulators: The first insulator

In 1837, Samuel Morse invented the telegraph technology, which made it possible for electrical signals to propagate along wires, realizing the communication method for humans to transmit and exchange information over long distances. Seven years later, with the construction of the first 40-mile wired communication line between Washington and Baltimore, the world's first telegraph insulator came into being in 1844.

Electricity began as a public utility in 1882 when Thomas Edison built the world's first power plant in New York City. The plant consisted of six DC generators and supplied electricity to users in a nearby area of approximately 2.6 square kilometers at 120 volts.

Nikola Tesla, a young immigrant from Serbia, was a young engineer at Edison Electric Company. He felt strongly that it might be safer and more efficient to use alternating current to supply electricity to users. With this dream, Tesla invented the world's first alternating current generator and obtained a patent for the alternating current transmission system in 1888. In 1893, Tesla's alternating current lit up the World Columbian Exposition in Chicago. Four years later, along with the construction of the alternating current transmission line, the world's first power insulator came into being in 1897.
