Abstract
The invention provides a multicore inflaming retarding fire resistant cable with a control cable core. The multicore inflaming retarding fire resistant cable with the control cable core comprises a twisted circular control cable core and a circular conductor; a corrugated insulating layer covers the circular conductor in a squeezing mode to form into cable cores; the twisted circular control cable core and a plurality of corrugated cable cores are twisted to form into a circular cable core; an external protective layer covers the cable core in a squeezing mode. According to the multicore inflaming retarding fire resistant cable with the control cable core, electric power and control signals can be simultaneously transmitted, a structure between the electric power cable core which is in a corrugated structure and the control cable core is compact, the gap between cable cores is small, inflaming retarding or fire resistant materials such as a glass cord, a glass fiber tape, a mica tape and an asbestos cord is not required to be used, production costs are reduced, and the inflaming retarding performance is reliable. The conductor adopts a circular compressing structure, the technical difficulty is small, and the insulating layer is not damaged. A protective layer is arranged according to different utilization occasions and the multicore inflaming retarding fire resistant cable with the control cable core is suitable for various severe occasions.
Description
Technical field
The present invention relates to power cable field, specifically a kind of multicore flame resistant cable with controlling cable core.
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 corrugated conductor in prior art, extruded insulation forms stranding after corrugated 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 corrugated conductor: one is that technology difficulty is large, in order to meet the enough flexibilities of corrugated 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, reduces gap between conductor, and corrugated conductor to be corrugated press, the shape of every layer is different, the difficulty increase of pressing; Three is easily cause electric field to concentrate in each angle course of processing of corrugated 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.
Summary of the invention
The present invention in order to solve the problem of prior art, provide a kind of compact conformation, cost be low, technology difficulty is low, flame-retardant performance is good, simultaneously transferring electric power and control signal, the band that is applicable to various severe occasion can control the multicore flame resistant cable of cable core.
The present invention includes stranded circle and control cable core and round conductor, be extruded with corrugated insulating barrier outside described round conductor, form core, stranded circle controls cable core and the many circular cable cores of the stranded formation of corrugated type core, outside cable core, be extruded with outer jacket.
Between described cable core and outer jacket, one better has one deck to tighten layer, and described tightens layer, can be wrapped, vertical bag, weave or extrude, a kind of fire proofing preferably woven, improve on braid, being coated with flame-retardant coating further.
Described stranded circle controls cable core, for lay configuration or can be extruded with round insulation sheath composite bed.
Described round conductor, one is better round compacted comductor, improves round compacted comductor further for pressing circular molded line conductor.
The described corrugated insulating barrier extruded, can be squash type or crowded tubular type, one be better squash type.
Described outer jacket, different according to use occasion, can be provided with one or more layers, as armour, screen etc., a kind of each layer of better outer jacket adopts the common structure of flame resistant cable.
Beneficial effect of the present invention is: can simultaneously transferring electric power and control signal, power cable core is corrugated structure, and control compact conformation between cable core, between core, gap is little, do 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.
