Power network telecommunication

PowerLink technical data

Answers for infrastructure & cities.

First choice for a seamless flow of

information between substations
PowerLink offers the energy industry the ability to
monitor and protect their networks even in places
which have no fiber-optic networks or where they
are not economically viable.

Regardless of the situation, PowerLink can be used as a

backup system to ensure a continuous flow of information
even in the event of a fault. PowerLink can be flexibly integrated into the existing infrastructure. Its compatibility
with all relevant transmission solutions and the ability to
continue to use existing infrastructure testify to how cost
effective this communications technology is. It has proven
itself over decades and is continually being refined.
