PRODUCT SPECIFICATION - 100FT 22 Gauge 6 Conductor Shielded Plenum Cable. Rated voltage: 300V. Rated working temperature from -10/14 to 80/176. HIGH CONDUCTIVITY - MOOKEERF 22 AWG shielded wire is built with stranded pure copper conductor,which has better conductivity,lower resistance and corrosion resistance than CCA (copper clad aluminium),providing maximum conductivity and reliability to ensure that your fire alarm systems run smoothly. CMP PLENUM-RATED CABLE - Our low voltage electrical wire use flame retardant materials for improved safety,ensuring optimal pressure resistance and good fire performance attributes.It features a CMP/CL3P/FPLP (Plenum-Rated) flame-retardant rating that provides peace of mind in case of fire. EASY TO USE - Stranded pure copper offers a variety of benefits when compared to solid wiring. Our security alarm control cable is flexible enough to be bent arbitrarily and can be comfortably fitted even in narrow corners,reducing entanglement dur
