Flame retardant optical cable for coal mines with loose sleeve structure (MGTSV cable)
Product description:
The structure of MGTSV access cable is to insert 250μm optical fiber into a loose sleeve made of high modulus material, and fill the loose sleeve with waterproof compound. The center of the core is a metal reinforcement core, and for some core number cables, a layer of polyethylene (PE) needs to be extruded outside the metal reinforcement core. The loose sleeve (and filler) is twisted around the center to make a compact and circular core, and the gaps in the core are filled with waterproof filler. The double-sided plastic-coated steel strip (PSP) is longitudinally wrapped and extruded to form a flame-retardant sheath. Suitable for: pipeline, overhead, direct burial.
Product features:
1、Has good mechanical properties and temperature characteristics
2、The loose sleeve material itself has good resistance to hydrolysis and high strength
3、Filled with special grease inside the tube to provide critical protection for the optical fiber
4、Specially designed tight optical cable structure to effectively prevent sleeve shrinkage
5、Good pressure resistance and flexibility
6、Special sheath material has excellent flame retardancy
7、The following measures are taken to ensure the waterproof performance of the optical cable: 1、single steel wire center reinforcement core; 2、loose sleeve filled with special waterproof material; 3、complete core filling; 4、double-sided coated steel strip (PSP) to improve the cable's moisture resistance
