18 AWG 3-Conductor FEP Plenum 150°C Shielded Cable

18 AWG 3-Conductor FEP Plenum 150°C Shielded Cable

The RWC-FP18-3S is an 18 AWG, 3-conductor FEP plenum cable with an overall foil shield, similar to Belden 88770. Three 19x30 stranded tinned copper conductors are individually insulated with FEP and protected by an overall 100% aluminum foil shield with a 20 AWG stranded tinned copper drain wire. The red FEP outer jacket brings the overall diameter to 0.155 in (3.94 mm).

Rated CMP per NEC Article 800, this cable is approved for installation in plenum air-handling spaces without conduit. The all-FEP construction handles continuous temperatures from −20°C to +150°C (UL rated 150°C) and provides inherent resistance to chemicals, oils, and UV exposure. The overall foil shield provides effective EMI/RFI rejection for sensitive signal applications.
