Chapter 7.1.3

Individually Shielded Multi Pair & Multi Triad PVC Insulated and Jacketed Foil Shielded 300V Instrument Cables

Physical Description

Power-Limited Tray Cables conforming to UL Subject 13 and NEC Article 725 Class 2 Circuits.
The cables can be used for instrument interconnections in process plant for LF control applications.
Each cable contains several individually foil-shielded twisted pairs or twisted triads plus a single 22 AWG communications wire.
The cables are overall foil-shielded and jacketed with FR-PVC compound.
