MGTSV flame-retardant optical fiber cable for mining applications features a dual-sheath design—PE inner layer and PVC outer layer—over Corrugated Steel Tape (CST) armor, providing enhanced chemical and abrasion resistance for corrosive or high-friction mine environments. Compliant with EN 50290-2-27, this cable excels in settings with acidic groundwater, slurry, or oil exposure, while its flame-retardant properties meet GB/T 18380.3 for self-extinguishing behavior. The stranded loose tube structure ensures fiber protection with gel filling, and steel tape reinforcement boosts tensile strength to 7000N, supporting reliable data transmission in deep or hazardous mines.
· Dual Sheath Protection: PE inner sheath provides abrasion-proof durability, while FR PVC outer sheath offers oil and chemical resistance and flame resistance for harsh mining surfaces.
· High Tensile Strength: Central metallic strength member and steel tape armoring allows high tensile loads, facilitating long pulls in mine shafts without damage.
· Flame Retardancy: Self-extinguishing per GB/T 18380.3, with low smoke emissions for safer use in confined underground spaces.
· Compact and Durable: Diameter as small as 10.5mm for 12-core versions, with UV-stabilized PE sheath containing carbon black for outdoor resilience.
· Operational Range: Functions from -40°C to +65°C, with gel-filled tubes preventing moisture issues in wet mine conditions.
· Salt and Potash Mines: Resists corrosive brines and chemicals in extraction sites, ensuring stable communication networks.
· Slurry and Pipeline Monitoring: Deployed along transport lines for real-time data on flow and integrity in mineral processing plants.
· Deep Shaft and Hoisting Systems: Supports automation in vertical shafts, withstanding friction and tension from hoisting equipment.
· Acidic Groundwater Areas: Used in mines with high acidity, where the PVC sheath protects against pH variations and erosion.
Q: What installation methods are recommended for this cable in mines?
A: It is suitable for direct burial in mine floors or suspension in shafts using corrosion-resistant clamps, with tension limited to 6000N during pulls.
Q: How does the outer PE sheath resist UV degradation in surface mines?
A: The sheath includes carbon black stabilizers, passing IEC 60794-1-2 UV tests for extended outdoor exposure without degradation.
Q: What are the crush test results for attenuation performance?
A: Under 1000N/100mm crush loads, attenuation change remains ≤0.1dB, ensuring signal stability in high-pressure zones.
Q: Can this cable handle oil spills in mining equipment areas?
A: Yes, the PVC inner sheath resists oils and hydrocarbons per IEC 60811, maintaining integrity in lubricant-rich environments.
Q: What is the temperature limit for storage before installation?
A: Store at -20°C to +50°C to prevent sheath brittleness, with installation possible down to -30°C with proper handling.
