Ignition cabling for high-pressure discharge lamps
11 June 2008
Interconnection
In shop-fitting applications, high-pressure discharge lamps are increasingly replacing fluorescent lamps. For electrical installation, this implies additional wiring. Wieland Electric now offers the gesis 5 kV plug-in ignition cable which connects ignition devices and lamps efficiently and safely.
High-pressure discharge lamps meet the requirements of correct colour rendering, energy efficiency, long lamp life and high operational reliability; however, they require additional wiring. The ballasts needed for generating the standard ignition voltage of 5 kV are located outside the lamps in most cases. Whereas a 3-conductor power cable is connected to the lamp in conventional lighting technology, here an additional 3-conductor wiring between ballast and lamp is required. This cable must be designed both for the 5 kV ignition pulse and for temperatures higher than 70°C.
The red coded plug connectors of the gesis cables reliably prevent confusing the 5 kV cables with pre-assembled 240 V power connection cables, by using black coding and a different plug face. The plug connectors are designed for plugging and pulling under load and are optionally available with spring force, screw-type or snap-in connector technology. All components meet the requirements of ignition voltage resistance according to DIN EN 60598-1, VDE 0711, para. 10.2 ff.
