Overhead/Underground Cable

Outdoor Over HeadUnder Ground Type, Single Loose Tube, Single Jacket Steel Armored Cable C/W 2×1.0mm Steel Messenger

The fibers, 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. The cable is completed with a polyethylene (PE) sheath.
