MGXTSWV For Duct Fcj Opto Tech 4-96 Core G652D Central Mining Cable Fiber Optic Cable

Short Description:

MGXTSWV Central mining cable , the fibers,200μm or 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape, over a thin inner PE sheath, the cable is completed with a polyethylene (PE) outer sheath.
