NOTICE
For very short cables with a cable length below 100 m we recommend
use of the guard on the far end as well as on the near end. This is possible
for 3 phase systems or systems where you have a second connection
from far end to near end .
Follow the introduction VLF withstand test with Tan Delta and guard
