Cable Section Design
Application
- ✰ Frequent lightning area and anti electric field : The subway, tunnel
- ✰ Long-distance communication: Local trunk network & User network
- ✰ Duct and direct buried application
- ✰ Harsh environment
Features
- Good mechanical and temperature performance.
- Special control of exceed length and layer stranding technology.
- Low attenuation and dispersion.
- Single armor and double sheath providing excellent crush resistance, water proof, and avoiding rat bite.
- FRP (non-metallic) Strength Member ensures good anti-electromagnetic interference.
- Stranded loose tube improves the tensile strength.
- Water -blocking material enhances water-blocking & moisture-proof.
- Friction reduction because the tube filling compound ensures a critical protection of the fiber.
- Double sheath design enhancing the crushing performance, good moisture-resistance, ultra violet radiation resistant.
