Stranded Loose Tube Armored Double Jacket Mining Optical Fibre Cable 4 Core Glass Fiber Optic Cable
This 4Core FO Cable is suitable for coal, gold, iron ore and other mines.
It has the flame retardant, rodent resistance property, so it is a good choice for mines.
Especially for the accident-prone land mines, to ensure smooth communication, reduce losses when the accident happens.
Features:
1. Good flame retardant performance.
2. High strength loose tube that is hydrolysis resistant.
3. Double sheathes and single armor providing excellent crush resistance, water proof, and avoiding rat bite.
4. Loose tube wrapped by non-weaven tape has the water blocking ability.
5. Special tube filling compound ensure a critical protection of fiber.
6. Blue PVC jacket: Flame retardant, the blue color is easy to identify.
7. Crush resistance and flexibility.
Application:
1. Professional usage for the coal industry
2. Tunnel shaft
3. Mine
