Technical field
The present invention relates to a kind of self-supporting fiber composite low-voltage cable.
Background technology
Along with State Grid Corporation of China builds strong intelligent grid implementation, the requirement that intelligent grid is joined, electricity consumption link information is mutual is improved gradually, the communication technology is to realize the basis that intelligent grid is joined, power information is mutual, is to realize electric network information, automation, interactive prerequisite and guarantee.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of self-supporting fiber composite low-voltage cable, realizes multi-purpose, saves conduit resource and significantly reducings the construction costs, and can adapt to the environment that lays of relative complex.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: self-supporting fiber composite low-voltage cable, comprise cable body, strutting piece and suspender belt, described cable body, strutting piece connect by described suspender belt, described cable body comprises nonwoven layer, the PVC external sheath layer of cable core and coated cable core, and described cable core is by optical cable unit, stranded the forming in low-tension supply line unit.
As preferably, described optical cable unit is stranded and coated waterstop, double plastic-coated wrinkle steel band of model, outer protective polyethylene cover by some loose tube fibers.
As preferably, described loose tube fiber comprises the loose sleeve pipe of at least one optical fiber and parcel optical fiber.
As preferably, described low-tension supply line unit comprises the high-voltage cross-linking polythene insulating barrier of at least one copper conductor and parcel copper conductor.
As preferably, between the each unit of described cable core, adopt dry type expansion water blocking yarn to fill.
As preferably, described strutting piece adopts that galvanized strand wires is stranded to be formed.
The present invention, owing to having adopted technique scheme, realizes multi-purpose, avoids repeating wiring, saves conduit resource and significantly reducings the construction costs; Adopt self-bearing type structure, can adapt to the environment that lays of relative complex.
