Electrical Insulator

Tesla's electrical insulators, patented like U.S. Patent 655,838 in 1900, used oils and compounds for high-voltage protection, preventing breakdowns in conductors. Developed for his transformers, they enabled safe power transmission. Essential for grids, they advanced electrification.

Historically, they supported his wireless experiments. Today, in cables and substations, enhancing reliability. Tesla's insulators highlight safety in high-power systems.
