Background
With the requirement of strategic construction of the national smart grid, the national grid can be used for constructing the smart grid nationwide. The intelligent power grid is based on a strong grid frame which takes an extra-high voltage power grid as a backbone grid frame and is coordinately developed with power grids at all levels, and is supported by a communication information platform, has the characteristics of informatization, automation and interaction, comprises six links of power generation, power transmission, power transformation, power distribution, power utilization and scheduling of a power system, covers all voltage levels, realizes multi-grid fusion of power flow, information flow and service flow, and has a modern power grid which is strong, reliable, economic, efficient, clean, environment-friendly, transparent, open and friendly in interaction connotation. In the medium-voltage section cable and the high-voltage section cable in the current market, an OPGW (optical fiber composite overhead ground wire) or an ADSS (automatic dependent Surveillance gateway) and the existing power conductor form a multi-network fusion concept, and in the medium-voltage section and the low-voltage section, namely a metropolitan area network or when a user accesses, the city appearance construction requirement is considered, the cable laying mode is often changed from the road to the underground, namely a pipeline and a direct-buried mode become more common, and therefore the optical fiber and the power conductor which are used for transmitting information are fused into one optical fiber composite cable, so that the optical fiber composite cable becomes the main force.
The optical unit in the newly developed layer-stranded single-sheath unarmored fully dry type composite cable adopts a loose tube fully dry type structure, namely, the effect of full-section water resistance and moisture resistance is realized by adopting a dry type water-blocking material in a tube or a cable core, and a brand-new access mode is provided in the cable construction by adopting self-supporting overhead laying.
Disclosure of Invention
The main inventive content of the central tube type double-sheath armored full-dry type self-supporting composite cable is that the optical unit adopts a full-dry type structure, namely, dry type water-blocking materials are adopted in the loose tube and the gap between the loose tube and the cable core to realize full-section water blocking, and the whole optical unit is of a nonmetal full-medium structure. Because the whole optical fiber composite cable adopts raw materials with excellent performance and a more appropriate structure, the optical unit has the characteristics of better heat insulation, compression resistance and tensile strength, and the whole cable has better electrical performance and optical performance, thereby completely meeting the requirements of intelligent power grid construction.
The central tube type double-sheath armored full-dry self-supporting composite cable has the following specific structure: this composite cable includes optical unit and conductor and cladding their oversheath, is equipped with steel wire suspension wire and outer jacket thereof in one side of outer jacket, is equipped with the suspender between oversheath and the outer jacket and links into an organic whole, and composite cable line part is from outside to inside in proper order: oversheath, armor, inner sheath, heat insulating tape, filler, light unit and conductor, the conductor by interior and outer cladding has conductor shielding layer, insulating shield, metallic shield, the light unit is central tubular light unit, and this central tubular light unit is from outside to inside in proper order: optical unit sheath, non-metal reinforcement, loose tube, dry type water-blocking object, optical fiber.
The conductor insulating layer, the filler and the outer sheath are made of flame-retardant materials.
Wherein the flame retardant material is PVC or LSZH.
