Nexans is launching a new range of 72.5kV cable and power accessories to meet the growing demand for higher capacity wind farms.
The company said the accessories have an F-type outer cone comprising separable T-connectors, coupling connectors and surge arresters.
It added that transformer and switchgear OEMs have also upgraded designs to cope with 72.5kV voltage rather than the current 36kV.
“As renewable energy becomes more prevalent, economic power supply becomes more and more important. There is now a new common standard for offshore wind connection systems up to 72.5 kV,” Nexans said.
It said all the 72.5 kV power accessories are type tested according to IEC 60840, while the equipment bushings by Euromold are additionally type tested according to IEC 60137.
Separable connectors and bushings are tested according to IEC 60068 – solar radiation IEC 60068-2-5 and salt mist IEC 60068-2-52 – with connectors, terminations and joints type tested according IEC 61238-1, Nexans added.
