Convenient and quick to install, easy to maintain
HARTING has designed new interfaces for the power supply of trains that are optimised for a long service life and sustainability. The Han® HPR High Performance Transformer Connector (HPTC) is a transformer interface specially developed for railway customers and outdoor use. The HPTC is pluggable and connects the converter to the transformer. The new interface is available in 400, 850 and 1400 A power classes, while voltages up to 3.6 kV/4.8 kV can be transmitted. An IP degree of protection up to IP69K can also be implemented.
One key advantage of HPTC is durability; previous solutions for transformer connection involved plastic outer casings, which are not tough enough to cope with the demanding and harsh conditions on the roof of rail vehicles. The HPTC offers a completely pluggable solution with a robust housing, based on the proven HARTING High Pressure Railway (HPR) standard. This enables a significantly longer service life.
New housing for jumper cables
The Han® HPR VarioShell was specifically developed for jumper applications. The two-part enclosure achieves protection class IP69K by using a counterpressure frame, in connection with a circumferential internal seal. The enclosure cover is removable, allowing efficient assembly from both inside and outside the carriage. Plug-in connections for wagon transitions on trains are a key feature of the housing and are now easier to access. Time and effort involved in operation, service and maintenance are significantly reduced. In the event of a fault, it is possible to open the housing cover, meaning there is no need to interrupt all connections.
Han® HPR TPL: Simpler power distribution in underfloor areas
To date, power distribution systems in underfloor areas have relied on UIC 552. The different interfaces of these systems each require their own installation technology and must be stocked separately. Thanks to the Han® HPR Train Power Line (TPL) all this now becomes a great deal easier, as there is only one completely pre-assembled Y-distributor as standard interface and single poles for the pluggable connection of the cables. Consequently, the TPL offers a uniform power supply across all wagons. What’s more, it is also significantly lighter than previous solutions, being around 10 kg lighter per wagon.
