Cross sections of data cables made using copper wire braid or carbon nanotube film shielding layersHouston, TX- 12/11/2018. Working in collaboration with Minnesota Wire & Cable Company, DexMat has produced carbon nanotube (CNT) tape shielded RG-316 cables that perform comparably to copper (Cu) double braid shielded RG-316 cables. However, the CNT tape shields are 95% lighter than the copper double braid shields. The shielding effectiveness and insertion loss results for the CNT and Cu shielded cables are shown below. The CNT tape shielded cables have the following advantages:

  • Overall RG-316 cable weight reduction of CNT shielded vs. Cu double braid shielded cable without connectors is over 50%
  • CNT tape shield is 100 microns thick compared to 500 micron thick Cu double braid shield
  • Easy to apply CNT tape to coaxial as well as twisted pair type cables
  • Wide range of CNT tape widths and lengths are available for purchase
  • CNT tape shielded cables survive at least 1000 flex cycles with a minimum bend radius of at least 7.5X the jacketed cable diameter
