Description

The MGTSV mining optical cable is designed with single-mode or multi-mode fibers housed in loose tubes made of high-modulus plastic, filled with water-blocking gel. The central strength member is a phosphated steel wire, or a phosphated steel wire extruded with a polyethylene (PE) layer. Loose tubes (or fillers and signal wires) are stranded around the central strength member to form a compact and circular cable core, with the interstices filled with water-blocking compound. The core is longitudinally wrapped with a steel–polyethylene laminated tape (PSP), followed by an inner sheath, and finally extruded with a blue flame-retardant PVC outer sheath. Fiber color coding can be either standard or full-spectrum.

Operating Temperature

−40℃ to +60℃

Bending Radius

Static: 10 × cable outer diameter; Dynamic: 20 × cable outer diameter

Applications

Suitable for inclined shafts and horizontal roadways in mining environments, offering enhanced mechanical protection and flame-retardant performance due to its double-sheathed structure.
