Feeder Cables
• Important role in signal transmission
• Materials and Construction-inner conductor: copper wire/tube, copper clad aluminiumwire-dielectric: PE foam with high degree of expansion-outer conductor: welded and corrugated copper tube-sheath: abrasion resistant PE
• Different cable sizes (most commonly used1/2", 7/8", 1 5/8") available to satisfy differentsite requirements
• Corrugation design enables tight bending
radius to ease installation
