Description
Technical field
The utility model belongs to technical field of electric wires and cables, particularly a kind of multicore flame-retardant composite cable with outer jacket.
Background technology
Along with taking place frequently of fire incident, people constantly deepen electric wire fire risk understanding, and the requirement of relevant department to performances such as electric wire fire protection flame retardings is also more and more higher.Features such as spreading fast, difficulty of putting out a fire to save life and property because cable fire has, produce secondary harm, recovery time is long can bring huge loss to the lives and properties of national economy and the people.Therefore fire-retardant, fire performance, the security reliability of people to electric wire proposes harsher service conditions.As strong in fire prevention, explosion-proof, overload capacity, long service life, the particular/special requirements such as under Fire Conditions, Fire lift, fire pump need keep the normal operation in certain hour, and cable is low-smoke low-halogen low toxicity after combustion, and even smokeless halogen-free is nontoxic.Cable-flame retardant, fire prevention measure reduce the important means that ignition of cable prolongs combustion, and key is being relied mainly on prevention, and all kinds of flame retardant cable, fire-resisting cable, fireproof cable are used widely.
Burning occurs any material all must possess following three conditions: combustible, oxidant and temperature (ignition source).The oxygen contained in air is a kind of oxidant, therefore, in Cable Construction Design, reducing gap between cable is a kind of conventional method with the existence that this reduces air, therefore, prior art often adopts the method arranging the fire-retardant or refractory material such as glass cord, glass fiber tape, mica tape, asbestos cord between each structure of cable, can improve fire-retardant, the fire resistance of cable.This method one is that use that is fire-retardant or refractory material can increase production cost in a large number, and two is fire-retardant or the performance of refractory material own is unreliable or have Shanghai to human body.In order to reduce the gap between core, 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.
Utility model content
The utility model is overcome the shortcoming that prior art exists, provide a kind of compact conformation, cost be low, technology difficulty is low, flame-retardant performance is good, can simultaneously transferring electric power and control signal, be applicable to the multicore flame-retardant composite cable of the band outer jacket of various severe occasion.
The multicore flame-retardant composite cable of band outer jacket of the present utility model, comprises cable core, tightens layer and outer jacket.Described cable core forms by some cores are stranded; Described layer of tightening is wrapped, the vertical fire proofing wrapping, weave or extrude.
As the further improvement of technique scheme, described in tighten layer be braiding fire proofing.
Another kind as technique scheme improves, described in tighten on layer and be coated with flame-retardant coating.
Another kind as technique scheme improves, and described core comprises round conductor and is extruded in the fan-shaped insulating barrier outside round conductor.
Another kind as technique scheme improves, and described round conductor is round compacted comductor.
Another kind as technique scheme improves, and has the round conductor of single line core at least for pressing circular molded line conductor in described several wire core.
Another kind as technique scheme improves, and described fan-shaped insulating barrier is squash type or crowded tubular type.
Another kind as technique scheme improves, and described outer jacket is one or more layers, comprises armour and/or screen.
The multicore flame-retardant composite cable of band outer jacket of the present utility model, with control cable core, can simultaneously transferring electric power and control signal, core is sector structure, compact conformation, between core, gap is little, does not need to use the fire-retardant or refractory materials such as glass cord, glass fiber tape, mica tape, asbestos cord, reduce production cost, flame-retardant dependable performance.Conductor adopts circle to press structure, and technology difficulty is little and can not Damage to insulation layer.Different according to use occasion, sheath is set, various severe occasion can be applicable to and uses.
