AREMA Class Insulation (Aerial) 600V Multiple Copper Conductors/90℃ Rating O is produced by Shanghai Laitao Cable Co., Ltd. It adopts ASTM B-3 standard solid bare copper conductor, high strength flame retardant and water-proof filler, high strength flame retardant PVC outer sheath. It is suitable for railroad signal circuits.
This document provides product data for Okonite aerial signal cables used in railroad signal circuits. It describes the solid bare copper conductors, the 4/64" insulation thickness, and the high‑strength Okosheath (CP‑TS) outer jacket that resists flame, oil and chemicals.
The cables meet AREMA and ICEA specifications, are rated for 600 V, and comply with IEEE 383‑1974 flame test. A table of catalog numbers, conductor sizes, and weights is included for reference.
| Voltage rating | 600 V |
|---|---|
| Insulation thickness | 4/64 in |
| Conductor material | Solid bare copper (ASTM B‑3) |
| Flame test compliance | Meets IEEE 383‑1974 Vertical Tray Flame Test |
The cables are rated for 600 V according to the AREMA Class Insulation specification.
The insulation thickness for those sizes is 4/64 in.
