High-current connector bridge keeps
trains live
A new high-current connector bridge is the ideal choice for providing safe and reliable electrical connections between adjacent rail cars.
A special sprung design, combined with exceptional flexibility, the ability to operate at up to 25kV, high fault current withstand capacity, and very competitive pricing make the new high-current connector bridge from interconnect specialist, Icore International, the ideal choice for providing safe and reliable electrical connections between adjacent rail cars Suitable for use on virtually all trains which have an overhead busbar system for power distribution, Icore's high-current connector bridges feature a weather-resistant sheath, and combine security of connection in service with easy, fast disconnection when cars need to be unhitched

The sprung construction used in Icore's high-current connector bridges is a crucial safety feature, since it ensures that, in the unlikely event of a jumper breaking or fracturing, its ends are held straight up and away from the ground, guarding against the exposure of passengers and railway personnel to the risk of making accidental contact with live conductors.
The springing system has, however, been carefully designed so that the jumpers retain excellent flexibility to allow for the inevitable movement of cars, relative to each other, while the train is in motion.
In addition, the use of a current-carrying braided conductor, which is independent of the spring system, means that wear on the conductors due to continual flexing is virtually eliminated.
Typical Icore high-current connector bridges are rated at 450A continuous, with a surge current rating of 45kA, and a contact resistance of less than 0.01.
They are designed for a nominal distance between cars of 16in, which can vary from 9 to 27in while the train is in motion.
Other requirements can, however, be accommodated easily and economically.
