Efficient Power Distribution (High Current / Voltage)
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 new Han® HPR HPTC series was specially developed for railway transformer applications. The Han® HPR standard enables use in harsh environments. Shielding can be reached without shrinking and taping.
Safety through simplicity
The demand for the greatest possible safety and simplicity determines the packaging, installation, operation and dismantling of the HPTC. Even the cartonnage contributes to simplicity through pre-structuring. Some parts are pre-assembled: the aluminium housing and internal insulating body are already connected, so they can be installed in the field quickly. The use of partly pre-assembled components increases the safety of the assembly. No special tools are needed.
Significantly faster installation
The time required to assemble Han® HPR HPTC interfaces is about half that of comparable products. This is due to the particularly simple assembly. Only a few parts are used and the pre-assembled components also help to improve increase safety. On the cable side, a crimped contact is inserted into a three-part, touch-proof insulating body. In addition, there is a cable gland that protects against dust and moisture. The cable gland also forms part of the shielding that absorbs residual currents and transfers them to the housing.
Now simply add the cover (including seal), tighten the cable gland, and that's it. Shrinking or taping is not required, air and creepage distances are safely maintained. A separate shield discharge is not required.
Higher energy at the same temperature
The Han® HPR HPTC stands out among connectors of the same size due to its higher energy density. This increases flexibility in the application. The compatibility with the flange on the mounting side is critical for the application. On the transformer side, this increases the current-carrying capacity from 1250 A to 1400 A compared to conventional connectors. The Han® HPR HPTC therefore transmits significantly more energy at the same temperature.
High-quality materials ensure a longer lifetime
The housings are made of die-cast aluminium, the HPR surfaces are powder-coated and the contacts are silver-plated. In the case of the socket contact, there is also a special transfer element in the receptacle: two springs wrap around the pin in the socket and ensure the best possible contact, even when forces act on the cable or housing. HPTC interfaces are resistant to shock and vibration. Their contacts are thoroughly protected against external influences; after insertion, the contact is locked in place with a slide in the insulating body. This supports the plug connection mechanically. The housing, insulator and contact thus form a single unit. External forces first act on the cable gland, then on the slide and finally on the contact. The contacts are only subjected to a minimal load.
