EMC Protection
On certain ships, offshore installations and land-based buildings, protection is required against electromagnetic pulse (due to lightning or nuclear blast) and interference, electronic sabotage (synthetic EMP) and static electricity. Such protection puts special demands on the design of transit components.
Electrical interference is usually combated in transits by including a tempered metal sheet in blocks and components, which together systematically stop electrical disturbance from passing along the cable screening through the seal and successfully act as an extended wall screen.
