Abstract

The utility model relates to a high-capacity copper-clad steel composite optical cable used for three-network convergence. The cable comprises an optical fiber conduit tube and a copper-clad steel wire, wherein the optical fiber conduit tube and the copper-clad steel wire are twisted to a central reinforcing core, and the outer layer of the central reinforcing core is twisted by the copper-clad steel wire to form an electricity conducting base. The utility model is not limited by the safe distance from the ground and the crossing, and truly realizes the perfection amalgamation of electric energy transmission and optical fiber communication; the steel wire is uniformly cladded by the copper liquid at a semi-solid state, so as to prolong the service life at least by 50 years to 80 years; and the copper-clad steel composite optical cable is not limited by the short-circuit thermal limit, so as to solve the defects of strand breaking from lightning stroke, overheated short-circuit current, cable breaking from electrocorrosion, and the like.

Description

High-capacity copper-clad steel composite optical cable for fusion of three nets

Technical field

The utility model relates to a kind of composite cable, especially relates to a kind of high-capacity copper-clad steel composite cable with electric power overhead phase line and optical communication dual-use function.

Background technology

The present ordinary optical cable that adopts in the power communication industry, it is restricted to have a little leap of capacity, the fail safe of transmission line and reliability instability, especially subject to be struck by lightning disconnected strand, intermediate current can not transmit fast, and non-refractory, overheat short circuit, defective such as corrosion-resistant difference and useful life are short.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of restriction that is not subjected to safe distance over the ground and scissors crossing, really realizes the high-capacity copper-clad steel composite optical cable for fusion of three nets that the perfection of electric energy transmitting and optical fiber communication is merged.

The technical scheme in the invention for solving the technical problem is: a kind of high-capacity copper-clad steel composite optical cable for fusion of three nets, comprise optical fiber spool and copper covered steel wire, described optical fiber spool and copper covered steel wire are twisted into the center strengthening core, and the skin of described center strengthening core is by the stranded conducting base that forms of copper covered steel wire.In order to make this product that high conductance be arranged, and can corrosion-and high-temp-resistant, not being subjected to short circuit and heat-staple restriction, described copper covered steel wire is coated on the high-carbon steel core by hot dipping copper layer and constitutes.

The utility model has the advantages that: be not subjected to the restriction of safe distance over the ground and scissors crossing, the real perfection fusion that realizes electric energy transmitting and optical fiber communication, improve grid automation, the dispatching communication level is a telecommunications network, computer network, cable television network can provide to comprise language, data by technological transformation, comprehensive multimedia communication service such as image, and can not reduce the fail safe and the reliability of transmission line; Adopt hot dipping copper layer bag high-carbon steel core, its advantage is that steel wire is wrapped plating in semisolid uniformly by copper liquid, has improved 50 ~ 80 years useful life, and the copper covered steel composite cable is not subjected to the thermally-stabilised restriction of short circuit, avoids being struck by lightning disconnected strand, and short circuit current is overheated, defectives such as the disconnected cable of galvano-cautery.

Embodiment

A kind of as shown in Figure 1 high-capacity copper-clad steel composite optical cable for fusion of three nets, comprise optical fiber spool 1 and copper covered steel wire 4, it is characterized in that: described optical fiber spool 1 is twisted into the center strengthening core with copper covered steel wire 4, the skin of described center strengthening core is by the copper covered steel wire 4 stranded conducting bases that form, and described copper covered steel wire 4 is coated on high-carbon steel core 3 by hot dipping copper layer 2 and constitutes.

This composite cable is not subjected to the restriction of safe distance over the ground and scissors crossing, the real perfection fusion that realizes electric energy transmitting and optical fiber communication, improve grid automation, the dispatching communication level is a telecommunications network, computer network, cable television network can provide to comprise language, data by technological transformation, comprehensive multimedia communication service such as image, and can not reduce the fail safe and the reliability of transmission line.The copper covered steel composite cable owing to adopt hot dipping copper layer bag high-carbon steel core, its advantage be steel wire when semi-cured state, be 20% ~ 90% can satisfy the various conductance grades of customer requirements by copper liquid bag plating conductance, high temperature resistant 〉=1080 ℃.Improved 50 ~ 80 years useful life, the copper covered steel composite cable is not subjected to the thermally-stabilised restriction of short circuit, can avoid being struck by lightning disconnected strand, and short circuit current is overheated, defectives such as the disconnected cable of galvano-cautery.Because the copper-clad steel core has excellent conducting performance and higher economic current density, can satisfy the big capacity of extreme high voltage, big electrical network, the requirement of super large short-circuit current capability system.Has higher mechanical strength simultaneously, tensile properties is good, mechanical electric apparatus characteristic coupling, long-term heat resistance can be good, do not need to use high-temperature resistant optical fiber, general communication optical fiber can satisfy long-term serviceability temperature, is to useful the replenishing and use and extend of ordinary optical cable as a kind of novel integration of three networks high-capacity copper-clad steel composite cable.
