  • Voltage feed through apparatus having reduced partial discharge
    Patent number: 4185164
    Abstract: A voltage feed-through apparatus having reduced partial discharge having an electrical conductor and an electrical terminal connected thereto. A semi-conductor sleeve surrounds the conductor for reducing the electric field concentration at the metallic conductor surface and consequently reducing the partial discharge occurrences. An insulator sleeve encircles the semi-conductor sleeve. A metallic sleeve surrounds a portion of the terminal. Another insulator is connected to the metallic sleeve and surrounds a portion of the insulator sleeve forming a space therebetween. Another metallic sleeve spaced from the first metallic sleeve surrounds a portion of the other insulator.
