Layer-stranded ribbon fiber cable for electric power or communication
The invention belongs to the field of fiber cable technology, in particular to a layer-stranded ribbon fiber cable for electric power or communication. The ribbon fiber cable comprises multiple loose tubes outside a reinforcing piece and a small filling rope in an outer gap of every two adjacent loose tubes. The loose tubes and the small filling ropes are provided with a protection layer outside. The exterior of the protection layer is coated by a sheath layer in an extrusion molding manner. The fiber cable is characterized in that multiple fiber cable ribbons are arranged in each of the loose tubes; each of the fiber cable ribbons is provided with multiple optical fibers and multiple fiber cable ribbon resin coating the whole optical fibers; there is no other visible filling matter except for the fiber cable ribbons in gaps of the loose tubes; and there is no visible filling material in gaps formed by the loose tubes, the reinforcing piece, the small filling ropes and the protection layer. The beneficial effects are that the fiber cable ribbons have quite high water resisting performance; cost of the fiber cable is quite low; the fiber cable is quite environmentally-friendly and light; detection and construction are quite convenient to perform; and production environment is quite clean.
