Rail Product Overview 19
Pantograph systems are expected to work harder as
train manufacturers continue to develop faster trains.
If the pantograph is detached from the wire, arcing can
occur, reducing the life of the wire and carbon strip.
Our LR27H high flow precision regulator is a fast response, high flow precision regulator, which
enables the pantograph to respond to the height variations on electric overhead lines.
The pressure regulator is the heart of the pantograph system, as it regulates
and maintains the force of the carbon strip onto the overhead wires.
As the wires are mounted between supports, the pantograph needs to extend and retract with
the height variations of the wires. The faster the train, the faster the reaction time needed.
It provides unrivalled performance, with a rapid, quiet and stable
operation, in a temperature range of -40°C to +80°C.
