애플리케이션
MV Submarine Power/Optical Composite Cables are designed for medium-voltage power transmission and simultaneous optical communication in offshore and subsea environments. 그들은 널리 사용됩니다:
- Offshore wind farm internal grid connection and communication
- Inter-island power and data transmission
- Coastal industrial facilities and offshore platform power supply
- Subsea renewable energy projects (태양의, 조수)
- Short-to-medium distance subsea power and communication integration
These cables can be directly buried in seabed trenches, installed in submarine cable routes, or deployed in dynamic offshore applications, with excellent resistance to seawater corrosion, 정수압, 기계적 스트레스.
