Product description
Cable test truck
The cable test truck allows the insulation tests to
be carried out on the power cables without
accessing the feeder unit or disconnecting the
cables from the switchgear.
The use of these trucks foresees removal of the
switching device from the switchgear (circuit-
breaker or contactor) and its replacement with the
truck, as shown in figure 1.
During the racking-in phase in OneFit frame the
metallic shutter shall be open and the truck opens
the ANSI insulating shutters if present and, by
means of its connectors allows connection to the
switchgear cable side.
