• Medium Voltage cables 3.6/6 kV for the supply of signalling and auxiliary circuits
• Medium Voltage cables 1.8/3 kV used for track feeder circuit, with special fire performance
• Low Voltage cables 0.6/1 kV used for lighting and low voltage circuits, also halogen free
• Low Voltage cables 0.45/0.75 kV - flexible cables for equipment and rail track connections, also halogen free
• TERAIL Flex - Sector shaped conductor flexible for low voltage circuits, also halogen free
• TERAIL Afumex Subaqua 1.8/3 kV

Tailor-made solutions

TERAIL SUBAQUA

In order to meet the specific needs deriving from a special application (Tunnel with frequent ingress of water, either fresh or salt), Prysmian developed a new design for 1.8/3 kV power cable with EPR insulation and LS0H anti-termite sheathing material: TERAIL Subaqua.

This cable leverages the excellent electrical ageing properties of EPR and avoids using metallic sheath or expensive swelling materials. Some of the benefits guaranteed by this solution are:

• Water resistance - no water treeing - longer life-time
• Higher overload temperature - safer
• Better partial discharge resistance, no shrink-back, flexibility – better tolerance to jointers’ errors
• Lead Free - Health and Safety - environmental benefits
• Lighter, longer delivery lengths, lower number of joints, reduced jointing costs and jointing problems
• Lower total investment cost
