DEVICE FOR LIGHT TRANSMISSION BETWEEN TWO POINTS HAVING OPPOSITE ELECTRIC POTENTIALS AND METHOD FOR MANUFACTURE OF SUCH A DEVICE

摘要

fiber-optic communication lines. SUBSTANCE: the device has a high-voltage insulator, whose cavity accommodates light guides and is filled with plastic foam foamed with gas of sulfur- hexafluoride. Foam surrounds light guides and fixes them in the preset position. Positive pressure is built up in the insulator cavity, and the cavity is hermetically closed. EFFECT: enhanced reliability of the device, reduced cost of manufacture. 6 cl, 1 dwg
