Technical features: low loss, low dispersion, compact structure, good comprehensive mechanical properties, allowable lateral pressure (n/100mm): long-term: 300, short-term: 1000 allowable tension (n): long-term: 600, short-term: 1500 allowable bending radius : 20 times the. specifications under which the various work for trenching & laying of optical fiber cable are to be executed by the Vendor. Our fiber optic cables are designed to meet high-survivability standards and repeatedly endure the severe mechanical and environmental stress found in surface and subsurface mining. Health Health For For LV & Safety LV Safety & application, Safety application, Management Management usually usually refers Systems refers Systems to to X-90 X-90 grade. The utility model relates to a vertically-laid optical cable for mines, which is characterized in that the optical cable comprises an optical fiber (6), a first aramid fiber layer (1), an inner optical cable jacket (5), a hose (2), a woven net pipe (4), a second aramid fiber layer (7) and an outer. Mining is one of the industrial sectors where the cabling systems have high requirements regarding security and mechanical.
