Han® HPR HPTC Series

HARTING's Han HPR high-performance transformer connector (HPTC) series was specially developed for railway transformer applications. Transformer connections are exposed to environmental influences, including mechanical impacts, water, oil, direct sunlight, and ozone, all of which can negatively influence the lifetime of the connections. The Han HPR standard enables use in harsh environments. Hoods, housings, and cable glands have been optimized for outdoor use; everything is designed to be very robust, so the connection between a pantograph, transformer, and train busbar remains stable over the long term.

The Han HPR HPTC simplifies installation. No shrinking or taping is required to set up transformer connections. The interfaces are quick to prepare; crimp the contacts, insert the insulating body with shielding into the housing, close the cover, and the cable side is ready.

Numerous encoding options are available. Two coding elements in the mounted housing open up 16 different combination possibilities. One connector type is therefore sufficient for the transformer connection; everything else can be controlled via coding. This significantly reduces the inventory needed and helps to reduce costs.

The Han HPR HPTC series is retrofit. The transformer side has the same dimensions as existing solutions in the market. Existing contours on the transformer can be reused, meaning design changes are not necessary. Customers can use the HARTING housing system to replace former solutions.
