KEC has developed a purpose-built test box for Alstom Grid. The new KA0916 plugs into Alstom Grid VBE cabinets that are used as part of the company’s high voltage, direct current (HVDC) electronic power transmission systems.

The test box is used as part of the annual maintenance checks allowing operators to configure data back into the VBE cubicles, check for faults and ensure all functions are working correctly.

The design uses a DGA25M30 backshell from the KEC ‘Inotec’ range. This is drilled to receive four toggle switches and a push switch that are internally wired to a high density ‘D’ type connector to interface with the VBE cabinet. Blanking plugs are fitted in the unused open cable entry points to ensure high levels of EMC throughout the system.
