KEC has again demonstrated its versatility in EMC interconnect assembly by developing a purpose-built EMC test box for Alstom Grid.
The box, designated the KA0916, plugs into Alstom Grid VBE cabinets that are used as part of the company’s high-voltage, direct current (HVDC) electric 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, such as trip settings, are working correctly.
The KEC design uses a standard 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. The prototype was evaluated, tested and approved by Alstom Grid and the assembly is now in full production.
“KEC has supplied cable harness assemblies to Alstom Grid for a number of years and used its many years of knowledge and experiences in EMC interconnect to design this test box that helps us to maximise the reliability of our HVDC distribution systems. The project was completed on time and within budget,” said Richard Reynolds of Alstom Grid UK.
