Railway signalling cables
APAR’s rail signalling cables incorporate a unique design to ensure the smooth running of railway networks. These cables are used for control and signalling,
which keeps rail networks moving safely. They are suitable DC circuits, where the nominal voltage to earth does not exceed 1100 V, and are suitable for installation in ducts.
| Application | Based on their application and design, these cables are ideal for internal applications, like free wiring installations in ducting, relay rooms, signal boxes, REBs and location cases. Some designs are used between equipment boxes, signal boxes, relay rooms and location cases. Others are for tunnels and underground purposes. These cables are suitable for AC systems (earthed or unearthed), for rated voltages up to and including 1100 V, and DC systems for rated voltages up to and including 1500 V to earth. |
|---|---|
| Characteristics | Cables with these specifications have the advantage of elastomer or Low Smoke Zero Halogen (LSZH) type insulation over the tinned copper conductors. Their voltage ratings are 650/1100 V, and they have an operating temperature range of -25°C to +85°C. |
| Applicable standards | IRS: S 63/2007 |
| Product range | Heavy-duty EPR insulated, and heavy-duty PCP sheathed single, twin and multi core cables.Light duty LSZH sheathed single and multi core cables for internal use.TYPE A/B/C/D/E 1, 2 & 3 railway signalling cables. |
| Advantages | These cables ensure that there is no interruption in the transmission of signals, and ensure continuous power supply alongside tracks for signalling. |
