EMC Compliant VSD SWA Motor Cable
EMC Compliant VSD SWA Motor Cable
(OP)
According to the GAMBICA / REMA guide on best practice for the installation of Power Drive Systems (Guide 3). http://www.gambica.org.uk/
3.4.2.3 PROTECTIVE CONDUCTOR (EARTH) CONNECTION.
To operate as a protective conductor, the shield conductance must be at least 50% of
that of the phase conductor.
According to this SWA Conductivity Info:-
http://www.batt.co.uk/catalogs/industrial/Other%20Technical%20Information/247.pdf
All 3C XLPE BS5467 cables 6mm2 & above have a Maximum armour conductivity expressed as a percentage (%) of one phase conductor less than 50%.
This means using 4 core cables from 6mm2 up to 16mm2 & 3 core with separate half size cpc for cables over 16mm2 (as advised by ABB).
What do others think about this?
