Alternate lightning arrester connector materials; FY 1988 process development endeavor: Final report
The Lightning Arrestor Connector (LAC) was developed to minimize the danger which would result from a lightning strike on aircrafts, missiles, and missile sites containing nuclear warheads. Because the danger occurs from lightning current entering the weapon through cables and connectors, the LAC was designed to short the electrical pulse to ground. The LAC device relies on a Dielectric Stimulated Arc (DSA) which is defined as the breakdown between electrodes in air triggered by a solid insulator of a high dielectric constant bridging the electrodes. The breakdown voltage is significantly reduced by the presence of the insulator. This LAC process development endeavor began in an attempt to replace one of the current LAC materials, rutile, or titanium oxide (TiO{sub 2}) [6 to 8 mils in diameter] in the spacing between the pins and the web of the connector. This evaluation investigated the use of commercial ceramic capacitor materials for use as LAC granules. Commercial ceramic powders from two different suppliers were selected for this evaluation. From each, several different products representing a wide range of materials and dielectric constants were sampled. All materials were processed into granules using rutile processing techniques. Granules and dielectric constant disks should be processed in the same manner as in these experiments, and results should be compared. 25 figs., 13 tabs.
