Next generation of power connectors for rail

Smiths Interconnect announces today the release of the next generation of its modular Transformer Connector Range – Heavy Power Series, for on-board power applications within the rail market.

The Transformer Heavy Power Series employs a specialist do-it-yourself system based on the building block principle that allows manufacturers in the Railway industry to design their own interconnect solution by procuring the connector’s elementary piece parts. This translates into design flexibility and cost savings by reducing supply chain, cabling and maintenance costs, at the same time ensuring quick and flexible time to market. 

The key innovation of the next generation of the Transformer Heavy Power Series is Smiths Interconnect’s Tortac® technology, boasting the characteristics of the Hypertac hyperboloid contact on equal pin diameter to feature smaller pitches, higher contact density and higher current ratings.

Suitable for on-board applications requiring the transmission of very high currents such as power distribution, inter-coaches and bogies, the Transformer Heavy Power Series has been designed according to EN50124 PD4 to ensure the reliability of the interconnect solution in high voltage applications operating in a polluted environment. It contributes to prevent breaks down caused by overvoltage issues, while ensuring passengers’ safety. In addition, design and testing is performed according to NFF61030 & EN50467.

The connector is available in 1 to 4 pole versions and supports up to 300A, a voltage rating of 3600V continue and a withstanding voltage of 12kV. It is easy to assemble due to the adoption of just three contacts and can be used with cross section cables from 25 mm² to 70 mm². An anti-swaying device on the connector’s back end provides a safe and reliable solution for the cables and simplifies the installation of the jumpers.

A plastic insulator with aluminum frame ensures optimum protection against ballast and allows for weight savings whilst playing an important role in reducing energy consumption. The materials used are in compliance with fire and smoke standards, according to NF F 16-101 & NF F 16-102 and EN 45545.

“Smiths Interconnect has designed a rugged, reliable and high-performance modular solution for railways applications, but also for hybrid and electric vehicles and various other industries.” said Paul Harris, VP Sales and Marketing. “The use of our distinctive Tortac® technology further enhances the connector’s performance and pushes the boundaries of innovation in design and manufacture of interconnect solutions to deliver a competitive edge to our customers.”

High Power Transformer Series Connectors

Transformer Series

Transformer Series offers a customer configurable architecture, with just a few piece parts to create several types of connectors as a platform solution. No special tools are needed except crimping tools, resulting in a reduced stock and kitting/logistic management. The series offers a high reliability due to the Tortac® contact and provides up to 500 mating cycles and high current rating up to 300A/500A.
