Encyclopedia > Cable layer

A cable layer is a deep-sea vessel designed and used to lay underwater cables for telecommunications, electricity, and such. A large superstructure, and one or more spools that feed off the transom distinguish it. Italian ship-rigged vessel Amerigo Vespucci in New York Harbor, 1976 A ship is a large, sea-going watercraft, sometimes with multiple decks. ... A cable is two or more wires bound together which may be bare, covered or insulated. ... // Sociological concept In social sciences, superstructure is the set of socio-psychological feedback loops that maintain a coherent and meaningful structure in a given society, or part thereof. ...

Telecommunications cable - Patent 5563377 (1523 words)
A telecommunications cable having a cable core in which each conductor is surrounded by an individual dual layer insulation of an inner layer of flame retardant polyolefin and an outer layer of fluorinated ethylene propylene.
In preferred cables, the fluorinated ethylene propylene layer has a minimum thickness of 2 mil to afford the required protection, the remainder of the insulated thickness being provided by the flame retardant polyolefin to produce the required electrical characteristics to the cable.
Surprisingly, although the flame retardant polyethylene conventionally is avoided for plenum cable constructions, in the invention and as shown by the embodiment it was shown that material is suitable as the inner layer insulation for plenum cables.
Differentially compressed, multi-layered, concentric cross lay stranded cable electrical conductor, and method of ... (1799 words)
The method of producing a compressed, multi-layered, concentric lay stranded cable of claim 13, wherein the circumferentially compressed cable is compressed to an overall outside diameter reduction of approximately 2.5 percent of its uncompressed diameter.
1, 2 and 3, the construction of the differentially compressed, multi-layered, concentric cross lay strand cable 10 of this invention comprises a central or core strand 12 with a plurality of strands concentrically arranged thereabout.
Additional layers of strands, more than illustrated in the drawing, can be employed for larger capacity cables, such as a fifth layer comprising thirty or other apt number of strands, a sixth layer comprising thirty-six or other apt number, a seventh layer comprising forty-two or other apt numbers, et seq.
