Description
Technical field
The utility model belongs to a kind of lightning protection cable for building in conductive cable technical field.
Background technology
Thunder and lightning has extremely huge destructive power, and its destruction is comprehensive, comprises the destruction of thermal effect, dynamo-electric effect, mechanical effect, blast effect, electrostatic induction effect and Electromagnetic Environmental Effect; Electric induction is divided into electrostatic induction and electromagnetic induction two kinds; Electrostatic induction is because thundercloud is close to ground, induces caused by a large amount of charges of different polarity at ridge top, ground.After thundercloud and other positions discharge, the electric charge at ridge top loses constraint, with lightning wave form, propagates as quick as thought along protrusion; Electromagnetic induction is that huge lightning current around space produces caused by vertiginous strong magnetic field due to after thunderbolt; The nigh metallic conductor of this magnetic field energy induces very high voltage, causes the secondary discharge to human body, thus damage electric equipment.China is the area that Lightning Disaster frequently occurs, and according to statistics, etesian Lightning Disaster has nearly ten thousand times, and the casualties caused has 3000 ~ 4000 people, and direct economic loss reaches tens to over ten billion RMB.Current city gets more and more when middle-high building, and along with the progress of technology, intelligent building is a development trend especially, but this kind of building is higher for the requirement of lightning protection.Prevent thunder and lightning from forming injury to building, most effective method carries out lightning protection, Contact patch mainly band steel, copper covered steel wire or copper stranded conductor, the copper covered steel twisted wire of current extensive use exactly.Though good conduction can be played when building at the beginning of this series products year long afterwards along with the corrosion of band steel, copper covered steel wire, lightning protection effect reduces year by year, and but produce stronger thunderstorm hour and can produce side and dodge damage wires body and contiguous building and electric equipment and can injure neighbouring personnel even, potential have unsafe factor, use is restricted, and also brings inconvenience to practical application.
Utility model content
In order to overcome the deficiencies in the prior art, solve existing lightning protection cable construction for building and design unreasonable, lightning protection properties is poor, the potential problem having unsafe factor.The object of the utility model is to provide a kind of simple and practical, lightning protection properties is good, possess good electric conductivity, against natural corrosive nature by own shield effect and insulation effect, effectively prevent side from dodging the building lightning protection cable bringing harm.
The technical scheme in the invention for solving the above technical problem is:
A kind of novel building lightning protection cable, it is provided with: fire-retardant supporting-core, ground connection inner wire, separator, insulating barrier ground connection outer conductor are held concurrently screen, outer separator, fire-retardant external insulation sheath, conductive cable core, the outsourcing of conductive cable core is connected with fire-retardant supporting-core, fire-retardant supporting-core and separator inner clip are surrounded by ground connection inner wire, the outsourcing of ground connection inner wire is connected with insulating barrier, insulating barrier outsourcing is connected with ground connection outer conductor and holds concurrently screen, the screen outsourcing of holding concurrently of ground connection outer conductor is connected with outer separator, and outer separator outsourcing is connected with fire-retardant external insulation sheath.
Above-mentioned novel building lightning protection cable, described ground connection inner wire is any one the ground connection inner wire wiry in copper wire, aluminium wire, steel wire, iron wire, or other adaptive type is wiry and the ground connection inner wire of radio frequency silk
Above-mentioned novel building lightning protection cable, described ground connection inner wire wire cross-section area>=50mm
2.
When the utility model uses, according to designing requirement, by this novel lightning protection cable general ply lay-ups in any position of building, do not limit by laid condition.Can bear the surge voltage being not less than 280KV, can play good lightning protection effect, flashing without side when complete double-layer insulating structure guarantees lightning impulse resembles generation and effectively protects contiguous building, electric equipment and neighbouring personnel.
Because the utility model design have employed technique scheme, electric conductor is coated in insulating material, there is excellent against natural corrosive nature, also coaxial configuration can be adopted, for transient current, there is low impedance characteristic, be convenient to the transmission of moment lightning current, and the use of coaxial shielding structure can suppress online in-core with the electromagnetic interference formed by thunder and lightning, prevents lightning induction to the infringement of sensitive electronic equipment; Adopt cheap fire proofing as expanding supporting-core, improve earthing conductor diameter, during reduction temporary impact, conductive surface field intensity, reduces insulation breakdown risk; The crosslinked polyethylene adopted, as insulating material, requires to carry out insulating Design with reference to system for high voltage cable grounding; Adopt flame-retardant insulating material as external insulation overcoat, both guard shield layers, can play certain insulating effect again, possess flame-retarding characteristic to increase fail safe during vertical run under construction simultaneously.It is unreasonable that it efficiently solves existing lightning protection cable construction design for building, and lightning protection properties is poor, the potential problem having unsafe factor.Show through several actual tests result on trial, it compared with prior art, have simple and practical, lightning protection properties is good, possess good electric conductivity, against natural corrosive nature by own shield effect and insulation effect, effectively prevent side from dodging and bring harm, advantage safe and convenient to use, is applicable to building lightning protection.
