Flame Retardant Fiber Optic Cable (Corrugated Steel Tape Armored)
This fiber optic cable features corrugated steel tape armoring and a flame retardant sheath, making it suitable for mining applications.
Description
This flame retardant mining cable has a central loose tube containing the optical fibers, which is filled with a filling compound. Water blocking material and corrugated steel tape (CST) protect the unitube. The outer layer is a flame retardant and anti-rodent sheath.
The cable offers excellent tensile strength, crush resistance, and anti-rodent properties, making it suitable for installation in demanding and harsh environments.
Application
This cable is designed for underground mining communications.
Features
- Small diameter and light weight for easy installation.
- Long delivery length.
- The special sheath material provides excellent flame retardant and anti-rodent properties.
- Hydrolysis resistant and high strength loose tube.
- Good mechanical and temperature characteristics.
- Corrugated steel tape improves the cable’s moisture resistance.
