<p>Coaxial lightning arrester with a coaxial connecting cable (5) being formed by a body (7) adapted at input and output ends for connection to the coaxial connecting cable (5) that is provided with a connector (9) for connecting a device to be protected wherein the coaxial lightning arrester is disposed in said body (7) longitudinal axis. The coaxial lightning arrester body (7) is provided at least at one end intended for connection to a device to be protected with a fixedly coupled, coaxial, hollow and cylindrical reducing adapter (1). In said reducing adapter (1) cavity, there is arranged the coaxial connecting cable (5) central conductor (2) with insulation. This central conductor (2) is directly connected inside the body (7) with the coaxial lightning arrester central conductor (4). Outer end of the cylindrical reducing adapter (1) is provided in its longitudinal axis with a cylindrical projection (11) for sliding on and securing said coaxial con necting cable (5) shielding. In the coaxial lightning arrester body (7) cavity, there is disposed co-axially about the coaxial lightning arrester central conductor (4) an insulating ring (6) for centering said coaxial lightning arrester central conductor (4). Diameters of the coaxial lightning arrester central conductor (4), the insulating ring (6) and the body (7) cavity are at the spot of mutual contact adapted for impedance matching to nominal impedance of the coaxial lightning arrester.</p> |
