Description
Overviewwhich 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, a
