Description
Technical field
The utility model relates to cable conductor field, and specifically a kind of multicore blocks water composite cable.
Background technology
The intrusion of moisture often power cable suffer to destroy, useful life affected main cause.Moisture immerses approach and mainly invades cable from the sheath of cable and the end of cable, causes the oxidation of conductor, corrosion, thus affects the electrical property of cable, even abnormal broken line accident occurs; Moisture infiltrates insulating barrier, and under the effect of highfield, insulating barrier can produce " water tree ", accelerates the voltage ageing of cable, causes cable breakdown accident, reduces cable useful life.In order to prevent the intrusion of moisture, require between each structure of cable closely very close to each other.
Prior art, in order to prevent the intrusion of moisture, multicore cable is generally many circular cores twisted synthesizing cable together with waterproofing rope or water blocking yarn, wrapped waterstop between primary structure, adopt the method for the water uptake expansion materials such as waterstop, waterproofing rope, water blocking yarn, water-proofing powder of arranging between each structure of cable, a large amount of hydrophilic radical that material water-proof material contains, will imbibition with water short-time contact, can absorb and conduct oneself with dignity into hundred times even water of thousandfold, there is fabulous water-retaining property.This method one is that the use of a large amount of material water-proof material can increase production cost, and two is the modes by water conservation, is absorbing the part of moisture, and moisture still can damage conductor or infiltrate insulating barrier.In order to improve the block-water performance of cable, also usually use sector conductor in prior art, extruded insulation forms stranding after segment conductor-core, and gap between core can be made to drop to minimum, but and gap between sheath still exist.Especially there is an a lot of difficult problem and drawback in process of production in the processing of sector conductor: one is that technology difficulty is large, in order to meet the enough flexibilities of sector conductor and stability, all higher to the characteristic requirements of the design of conductor structure, moulds of industrial equipment, equipment; Two is want conductor to adopt compact conductor for preventing moisture from infiltrating, and to improve the activity coefficient of wire, reduced outside diameter, reduce gap between conductor, and sector conductor is fan-shaped pressing, the shape of every layer is different, and the difficulty of pressing increases; Three is easily cause electric field to concentrate in each angle course of processing of sector conductor and damage cable insulation.
Along with the universal of computer technology and the develop rapidly of information industry, Intellectual district has become the development trend of modern architecture, by the comprehensive wiring system that is made up of composite cable etc. the communication in intelligent construction, computer and various equipment and facility, include comprehensive wiring system under certain conditions, be interconnected to form complete supporting entirety, to realize highly intelligentized requirement.Therefore power cable and control cables is often required to carry out compound.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of compact conformation, cost is low, technology difficulty is low, block-water performance is good, can the multicore of simultaneously transferring electric power and control signal to block water composite cable.
A kind of multicore described in the utility model blocks water composite cable, comprises circular cable core, and this cable core is by a fan-shaped control conductor and be at least that two fan-shaped insulated wire cores are stranded to be formed; Be outside equipped with at cable core and tighten layer; Described fan-shaped control conductor controls conductor by circle, be extruded in and circularly control the control insulating barrier outside conductor and at least outside control insulating barrier, be provided with layer protective layer to form; Described fan-shaped insulated wire cores by round conductor, be extruded in the insulating barrier outside round conductor and outside insulating barrier, be at least provided with layer protective layer and form; The protective layer of described fan-shaped control conductor is identical with the protective layer structure of fan-shaped insulated wire cores.
Further improvement, described tightening outside layer can be coated with pitch, forms bitumen layer.
Further improvement, described control insulating barrier shape can be circular or fan-shaped.
Further improvement, described insulating barrier shape can be circular or fan-shaped.
Further improvement, when described protective layer is one deck, this protective layer is fan-shaped armour.
Further improvement, when described protective layer is two-layer, the internal layer of this protective layer is circular shield layer, and outside is fan-shaped armour.
The beneficial effects of the utility model are: compared with prior art, the utility model is with control cable core, can simultaneously transferring electric power and control signal, core is sector structure, compact conformation, do not need between core to use the water uptake expansion materials such as waterstop, waterproofing rope, water blocking yarn, water-proofing powder, reduce production cost, block-water performance is reliable; Conductor adopts circle to press structure, and technology difficulty is little and can not Damage to insulation layer.
