fire resistant copper shield copper core PVC insulated twist



Field shield line is mainly used for lines, electrical instrumentation, telecommunications broadcasting, anti-theft alarm system, building intercom systems, video surveillance systems, electronic equipment and automation devices and the like. NH2-refractory added RVSP series on the basis of the RVSP, thus It has good fire resistance.


Conductor: stranded conductor
Refractory: mica tape
insulation: PVC insulation
shield: copper mesh braided shield
sheath: PVC sheath
