Optical Fibre Cable
MGTSV Flame-retardant Stranded Loose Tube CST Armor PVC +PE double Sheath Optical Fiber Cable for Mine
MGTSV
CST armour · PVC sheath · for underground mine communications
The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the metallic strength member to form the cable core filled with water blocking compound. Then the steel tape (CST) is longitudinally armored over the cable core and a PE inner jacket is extruded. Finally the cable is completed with a blue flame-retardant PVC jacket.
Key features
- Good mechanical and thermal performance
- Steel wire as the central strength member
- Hydrolysis resistant loose tube
- Tube filling gel ensures critical protection of fiber
- Specially designed stranded structure eliminating contraction of tubes
- Flame-retardant PVC jacket ensuring good fire resistance
- Water-blocking measures :
- – Loose tube gel-filled
- – 100% cable filling compound
- – Corrugated steel tape(CST) enhancing moisture-proof
