MV wind cable passes 10,000 torsion cycles at -40°C. EPR/butyl insulation, CSM sheath. 3.6/6kV-26/35kV, single/triple core. Salt spray/UV/ozone resistant.
Application
IEC 60502-2 medium voltage twisted resistant cable (3.6/6kV to 26/35kV) for wind farm medium voltage collector systems: turbine-to-turbine connections, turbine-to-substation feeders, and offshore wind farm array cables. Class 5 annealed copper, EPR/butyl rubber insulation, CSM sheath. Supports 10,000 torsion cycles at normal temp and 2,000 at -40°C. Single-core and three-core configurations. Operating temp: -40°C to +90°C. Flame retardant Class C. Resists moisture, salt spray, oil, UV, ozone.
Core Strengths
MV cables in wind farms face constant flexing and harsh marine salt spray. Our 6-35kV cable passes 10,000 torsion cycles and -40°C cold test. EPR/butyl insulation, CSM sheath. Single/triple core. 3.6/6kV to 26/35kV. Flame retardant Class C.
