Armored Aerial Signal Cable
These are multi-conductor 600- and 2000-volt signal cables specifically designed for use in railroad signal and control circuits in accordance with the AREMA Signal Manual. They are intended for aerial or duct installation for use wherever long service life is required. They consist of ethylene-propylene rubber (EPR)- insulated conductors, a cushion layer, helically applied bronze armor and a polyethylene outer jacket.
Product Construction
Conductor: Solid soft drawn, bare or tinned copper per ASTM B258 and B33. INSULATION: Heat and moisture-resistant EPR meeting the requirements of AREMA C&S Manual Part 10.3.19, suitable for a maximum continuous operating temperature of 90°C.
Circuit Identification: Black conductors with number print: (1-ONE, 2-TWO, 3-THREE, etc.). One black conductor with a red stripe serves as a tracer.
Assembly: The insulated circuit conductors are cabled together with non-hygroscopic fillers as needed. The cable core is wrapped in a binder tape.
Cushion Layer: Extruded layer of shock-absorbing polymer. An optional ripcord placed underneath the cushion layer is available upon request. Fabric tape is also available. ARMOR: 10 mil thick bronze tape helically-applied with a minimum overlap of 20%. An optional 10-mil-thick bronze tape, corrugated and applied longitudinally with a minimum overlap of 12.5%, is available upon request.
Overall Jacket: Heat and moisture-resistant black polyethylene (PE) meets the requirements of AREMA C&S Manual Part 10.3.21. Neoprene and LSZH XLPO are available. An optional ripcord can be placed underneath the overall jacket upon request.
