Underground 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 buried installation for use wherever long service life is required. They consist of insulated ethylene-propylene-rubber (EPR) conductors and a polyethylene outer jacket.
Design Parameters
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 conductor with an identifying 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.
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.
