Cable test termination systems are used for high voltage testing
of power cables. Before high voltage (AC or Impulse) can be
applied the power cable needs to be prepared and terminated
in a special way in order to control the electrical field distribution
along the ends.
The Haefely water-filled cable test terminations (CTT) and water
processing unit (WPU) offer the perfect connection for these
tasks. The new generation of CTTs are optimised for AC routine
testing and completed by a modern, easy to use WPU.
The CTT range covers rated AC voltages from 100kV up to 800kV
and are for diameters of 115, 130 or 165mm maximum across the
outer semiconducting layer.
Advantages include: short tubes for easy handling and less
cable waste, rugged design, hydraulic jacking system (manual or
automatic), new service friendly design, pneumatic valves ensure
partial discharge free operation and a modern user-friendly touch
screen interface.
