Mining Fiber Optic Cable MGXTBV
MGXTBV cable mainly carries optical communication signals in underground coal-mine environmental monitoring systems. Flame retardancy, moisture resistance and resistance to lateral pressure meet mine-environment safety requirements. The product requires national mining-product safety-mark certification, known as the coal safety certificate, to ensure compliance with coal-mine production safety standards. II. Structure and materials. Fiber protection: Fibers are placed in high-modulus loose tubes filled with a special water-blocking compound. Stainless-steel spiral armor and aramid yarn reinforcement improve tensile strength and resistance to rodent bites. A flame-retardant PVC jacket is generally blue for identification and passes bundled-cable flame testing. Central reinforcement: Phosphated steel wire or polyethylene-coated steel wire improves mechanical performance for complex installation environments.
