How can I absorb the vibrations from HV/LV transformers on a KT busbar trunking?
KTB0000YC shims are too rigid to absorb vibrations.
To absorb the vibrations from HV/LV transformers on a KT busbar trunking you should use braids, part number KTB0000YT1.
The number of braids depends on the rating of the trunking, for more details please refer to the product page.
