APPLICATION
Single-core MV copper power cables are designed for reliable medium-voltage power transmission and distribution in urban, 산업의, 및 인프라 환경. 그들은 널리 사용됩니다:
- Urban power grid renovation and expansion projects
- Industrial plant power distribution and substation connections
- Underground cable networks, 직접 매장, and duct installation
- Renewable energy projects (태양의, wind farm grid connection)
- Commercial building and data center power supply
These cables can be directly buried in soil, installed in cable trenches, 덕트, or tunnels, with excellent resistance to mechanical stress, chemical corrosion, and environmental aging.
