6  Submarine  cables
6.1  Preliminary  remarks
The  cables  and  accessories  used  must  be  state  of  the  art  and  meet  the  requirements  of  the
relevant  standards  in  each  case  (selection  see  below)  or  their  suitability  must  have  been
proven  by  comparable  tests  and  they  must  be  suitable  for  the  particular  operating  conditions/
applications.
Reference  is  made  to  the  specifications  of  the  Spatial  Offshore  Grid  Plan  (BFO)  in  the  current
version.  Only  one  approval  is  granted  for  the  cabling  within  the  wind  farm  and  the  power  output ­
  cable.

6.2  Technical  codes  of  practice
6.2.1  Cabling  within  the  wind  farm
For  test  requirements  and  suitability  certificates,  the  following  technical  codes  of  practice  in
their  current  version  must  be  complied  with  in  relation  to  alternating  current  transmission  using ­
  plastic-insulated  power  cables  (energy  distribution  cables):
DIN  VDE  0276-620  (VDE  0276-620)
