Product Description / PRODUCT

The MGTSV cable structure is made by inserting a 250 μm fiber into a loose tube made of a high modulus material, and the loose tube is filled with a waterproof compound. The center of the core is a metal reinforcing core, and the loose tube (and the filling rope) is twisted around the center reinforcing core into a compact and round core, and the gap in the core is filled with a water-blocking filler. The double-coated plastic strip (PSP) is longitudinally extruded and extruded into a polyethylene inner sheath, and the inner sheath is externally packed with a polyethylene outer sheath to form a cable.

Product Features / PRODUCT

　　 · Has good mechanical properties and temperature characteristics.

　　The loose tube material itself has good water resistance and high strength.

　　· The tube is filled with a special grease to protect the fiber.

　　· Good pressure resistance and softness.

　　• The following measures are taken to ensure the waterproof performance of the cable.

　　· Single wire center reinforcement core.

　　• The loose tube is filled with a special waterproof compound.

　　· Complete cable core filling.

　　· Double-sided coated steel strip (PSP) improves the moisture resistance of the cable and has the function of preventing rat.

　　• Good water blocking material prevents longitudinal leakage of the cable.

　　·Using blue flame retardant PVC for secondary sheathing, the cable has good flame retardant effect.

Product Standard / PRODUCT

· MGTSV fiber optic cable follows the test method and judgment rules of flame retardancy of MT386-1995 coal mine flame retardant cable.
