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 out 
put 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 us 
ing plastic-insulated power cables (energy distribution cables):
