APLICATIVO
Single-core MV copper power cables are designed for reliable medium-voltage power transmission and distribution in urban, industrial, e ambientes de infraestrutura. Eles são amplamente utilizados em:
- Urban power grid renovation and expansion projects
- Industrial plant power distribution and substation connections
- Underground cable networks, enterro direto, and duct installation
- Projetos de energia renovável (solar, wind farm grid connection)
- Commercial building and data center power supply
These cables can be directly buried in soil, installed in cable trenches, dutos, or tunnels, with excellent resistance to mechanical stress, corrosão química, and environmental aging.
CONSTRUÇÃO
- Condutor: Annealed Copper (Cu, Aula 2/5 encalhado)
- Tela do condutor: Camada extrudada semicondutora
- Isolamento: Polietileno reticulado (XLPE)
- Tela de isolamento: Camada extrudada semicondutora
- Metal Shield: Fita de cobre (CuTape) or copper wire shield for short-circuit current path
- Forro Interno: Camada de polímero extrudado (PE/PVC)
- Armadura: Armadura de fita de aço (STA) or Single Wire Armour (SWA) for mechanical protection
- Bainha Externa: Polietileno de alta densidade (PEAD) or Low Smoke Zero Halogen (LSZH) for environmental resistance
- Identificação Central: Color-coded conductor and shield layers per IEC standards
