Part B - Certificates and approval requirements 
T251 DIN VDE 0278-629-1 or 
1261 I EC 60502-4 
1271 DIN EN 61442 (VDE 0278-442) or 
1281 IEC 61442 
3.4.2.2 Connection to the power grid 
3.4.2.2.1 Alternating current transmission 
The following technical codes of practice in their current version are to be observed for test requirements 
and suitability certificates, with alternating current transmission using plastic-insulated power cables: 
T291 DIN VDE 0276-632 or HD 632 S1 or 
f301 IEC 60840 
f311 DIN VDE 0276-62067 (in preparation, status September 2006) or 
132] IEC 62067 
If tests on high-voltage submarine cables cannot be performed in accordance with the aforementioned 
standards, reference is made to the recommendations of CIGRE in their current version, published in 
the following Electra editions (house magazine of CIGRE): 
• CIGRE: Recommendations for Mechanical Tests on Submarine Cables f331 
• CIGRE: Recommendations for Testing of long Submarine Cables with Extruded Insulation for 
System Voltage above 30 (36) to 150 (170) kV f341 
• CIGRE: Recommendations for Testing long AC Submarine Cables with Extruded Insulation for 
System Voltage above 30 to 170 kV f351 
3.4.2.2.2 Direct current transmission 
The current version of the following CIGRE recommendation can be used for all direct current (DC) 
cables: 
• CIGRE Recommendations for Mechanical Tests on Submarine Cables f331 
The following recommendations of the CIGRE in their current version can be used for plastic-insulated 
direct current (DC) power cables: 
• CIGRE: Testing DC Extruded Cable Systems for Power Transmission up to 250 kV f361 
The following CIGRE recommendation can be used for cables with mass-impregnated paper 
insulation: 
• CIGRE: Recommendations for Tests of Power Transmission DC Cables for a rated voltage up to 
800 kV £3ZI- 
3.4.3 Environmental influences 
3.4.3.1 Electrical fields 
Shielded cables do not generate any electric field outside the cable. The limit value of 5 kV/m at 50 Hz 
in accordance with BlmSchV is therefore complied with without restrictions. A certificate according to 
BlmSchV shall be produced if using unshielded cables.
