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.
