New interfaces for the power supply of trains that are optimized for long service life and thus stand for sustainability: The Han ® HPR High-Performance Transformer Connector (HPTC)is a transformer interface specially developed for railway customers and
optimized for outdoor use. The HPTC pluggable connects the converter to the transformer. The new interface is available in the 400, 850, and 1400 A power classes, while voltages up to 3.6 kV/4.8 kV can be transmitted. IP degree of protection up to IP69K can also be implemented.
Key HPTC advantages: Previous solutions for transformer connection involve plastic outer
casings, which can lead to low durability under the demanding and harsh conditions on
the roof of rail vehicles. The HPTC, however, offers a completely pluggable solution
enabling significantly longer service lives compared to plastic housings. This is also due to
the robust housing, which is based on the proven HARTING High-Pressure Railway
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 wagon. Plug-in connections for the wagon transition for trains are an appreciated feature in the housing and at the same time are easier to access. Input and efforts involved in operation, service, and maintenance are significantly reduced. In the event of a fault, it is sufficient to open the housing cover, meaning that it is not necessary 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 necessitate their own installation technology and must be stocked separately. Thanks to the Han ® HPR Train Power Line (TPL) all this becomes a great deal easier: now, the is only one completely pre-assembled Y-distributor as a standard interface as well as single poles for the pluggable connection of the cables. Consequently, the TPL becomes a uniform power supply across all wagons. What’s more, the result is also lighter than previous solutions: The difference in weight per wagon compared to previous solutions tips the scales at around 10 kg.
