The next generation of power connectors for the railway industry

With the new generation of the modular Transformer Heavy Power series, Smiths Interconnect offers innovative and even more powerful connectors for on-board rail applications.

The products of the Transformer Heavy Power Series are modular in design. With the individual parts of the connector, manufacturers in the railway industry can design their individual connection solution. This flexible design reduces supply chain, cabling and maintenance costs.

The innovative Tortac® technology has the properties of the Hypertac hyperboloid contact with the same pin diameter. This enables smaller pitches, higher contact densities and higher rated currents.
