Belden 3073F C55, Twinaxial Cable 18 AWG 600V PVC Blue
Description
Belden 3073F C55 is a 100 Ohm twinaxial cable with 1 pair of 18 AWG (7x26) TC - Tinned Copper conductors, PP - Polypropylene insulation, and a PVC - Polyvinyl Chloride outer jacket. It features dual shielding with Beldfoil® (100% coverage, foil out) plus a Tinned Copper braid (55%) to help reduce EMI. The cable carries TC, PLTC, ITC, and CMG ratings, with UL voltage rating: 600 V (TC), 300 V (CMG, PLTC). It is listed for indoor/outdoor use with sunlight resistance and UV resistance, and it supports aerial installation when supported by messenger wire.
