Modular power connectors reduce cabling in railways
Developed for use on railway systems, Smiths Interconnect has launched the next generation modular transformer connector. The Heavy Power Series is designed for on-board power applications and is a modular system that is designed to reduce cabling and maintenance costs.
The Transformer Heavy Power Series is based on the building block principle that allows manufacturers in the railway industry to design their own interconnect system by procuring the connector’s elementary piece parts. This reduces supply chain, cabling and maintenance costs, whilst ensuring quick and flexible time to market, says Smiths Interconnect.
The Transformer Power series has Smith Interconnect’s Tortac technology, which draws on the exceptional characteristics of the Hypertac hyperboloid contact on equal pin diameter to feature smaller pitches, higher contact density and higher current ratings.
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 is 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 towards preventing break down caused by over-voltage issues, while ensuring passengers’ safety. In addition, design and testing is performed according to NFF61030 & EN50467, adds Smiths.
The connector is available in one- to four-pole versions and supports up to 300A, a voltage rating of 3600V continuous 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 to 70mm². 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 aluminium 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.
