<p>The filled casing is comprised of a cylindrical insulating envelope (9) and of two contact bodies (4). These bodies are provided with a flexible tubular lining (12) acting as a filling ring, previously expended by means of electron radiation, and, after introduction of these contact bodies into the envelope (9), they are heated, which further increases the thickness of the linings (12) which thereby fill the annular spacing between the contact bodies (4) and the insulating envelope (9) achieving the tightness of the casing.</p> |
