Draka - Rail Tunnel Infrastructure Cables

At Draka we know that the safety of occupants and passengers in mass transit systems, especially road and rail tunnels, is of paramount importance. One factor that can play a key role in making these environments safer is the appropriate use of fire-performance cables for critical safety systems.

TUNNEL FIRE-PERFORMANCE CABLES

In the event of a tunnel fire and smoke filled environment, it is vital that the emergency lighting remains secure, to ensure that escape routes are clearly illuminated. Moreover, the correct selection and installation of these vital safety cables ensures that, in the event of an emergency, systems can continue to function and people will have time to evacuate safely, as well as helping the emergency services to operate effectively.

CONNECTA TUNNEL FIRE-PROTECTION SYSTEM

The technical resources of Draka and Custom Design Group have combined to deliver a system that offers optimum fire safety performance in tunnels. Connecta is manufactured with high-quality injection moulded Zero Halogen, Low Smoke (OHLS®) components and features a male joint and female plug with an optional integral fuse and coupling nut.

EMERGENCY LIGHTING AND POWER SUPPLY PROVISION

Connecta is available with a primary cable of 2.5mm² to 50mm², in three, four or five-core variations and a wiring loom length of approximately 700m. This ensures the system is ideally suited to a wide variety of tunnel environments for the provision of emergency lighting and three-phase power supplies.

Another significant benefit of Connecta is the ease in which it can be installed and maintained. With project deadlines becoming tighter and tighter, Connecta offers both time and cost-saving benefits to a variety of applications.

With all of the lighting or power joints manufactured in a clean factory environment, rather than in-situ on site, installation times can be significantly reduced. This can assist in meeting or bringing forward project milestones or deadlines. In addition, with the jointing pre-manufactured, the need for highly skilled electrical installers can be reduced, as the system can be installed by semi-skilled labour, again offering a cost-saving benefit.

CONNECTA CUSTOMISED COUPLING SYSTEMS

Each coupling system is specifically designed and manufactured to meet the client's needs with pre-set lengths between each moulded socket outlet unique to each installation. Secondary outputs are then taken from the primary cable via moulded plugs to pre-wired individual luminaries. Therefore not only is Connecta easy to install, but, because of its modular design, maintenance is also simple.

Each Connecta is phase identified and circuit integrity meets the requirements of BS6387 categories C, W and Z. Ingress protection meets IP 67 standards. As part of the Firetuf range of fire performance cables, Connecta also benefits from being a OHLS system.
