Existing anti-explosion cable structure is made up of conductor and insulating barrier usually, its insulating barrier generally adopts PVC polyvinyl chloride or XLPE cross-linking polyethylene materials to be made, the insulating barrier resistance to elevated temperatures adopting PVC polyvinyl chloride or XLPE cross-linking polyethylene materials to make is poor, security reliability is poor, useful life is short, and cost performance is low; Or wrapped layer of non-woven fabric after stranding is filled, this construction of cable is simple, and shield effectiveness is poor, and tensile strength is also undesirable, does not have explosion prevention function, easily produces electric discharge, leaky, there is serious potential safety hazard.
And the existing cable with fire-proof function, fireprotection layer is all generally select mica tape or silicon rubber pottery mud or magnesium oxide, but these quality of materials weights, easy solidification, easily ftracture when after solidification, cable is installed bending, discharge a large amount of harmful poisonous aerosol gases during burning, production material technology is simultaneously complicated, easily to environment; And not long by the cable production length of above manufacture of materials, electric cable with large cross-section can not make one, cable quality weight, and cable pliability is poor, all brings great inconvenience to installation and transportation, and Cable Bending Radius is large, extrudes the defects such as easy core shift.
[summary of the invention]
The purpose of this utility model is the technical barrier that the shield effectiveness in order to solve above-mentioned anti-explosion cable is poor, security reliability is poor, adapt to the demand that development of modern industry is supporting, design that a kind of explosion-proof effect is good, tension is effective, high temperature resistant, shielding properties is high, can meet the fire-proof and explosion-proof cable of fire-proof and explosion-proof instructions for use.
To achieve these goals, design a kind of fire-proof and explosion-proof cable, comprise conductor and fixture, described conductor adopts that some copper wires are stranded to be formed, fire-proof and water-proof insulating barrier is wrapped up outside conductor, gap-fill explosion-proof lamp between the wire of parcel fire-proof and water-proof insulating barrier, fire-proof and water-proof insulating layer is wrapped up successively again outside interior, total screen and external sheath layer, described fire-proof and water-proof insulating layer bonds aluminium foil again after adopting ceramic fiber paper back adhesive glass fabric and forms, described fixture comprises insulator, conduit, fixed cover, be connected and fixed by fixed cover between two conduits, conduit side is provided with insulator and insulation crust.
Described ceramic fiber paper is replaced by ceramic fiber blanket or ceramic fiber cloth or ceramic fibre strip, plays the effect of explosion-proof, shielding demagnetization, the insulation of thermal insulation fire-proof and water-proof.
Described fire-proof and water-proof insulating barrier adopts silicone band, and two layers or more is wrapped outside conductor.
Described anti-explosion cable packing material is explosion-proof mud or high flame retardant glass fiber or ceramic fibre rope.
Described total screen adopts thin copper wire braiding, copper strips or the wrapped formation of aluminium foil, plays electromagnetic iris action.
Described external sheath layer selects environmental-friendly halogen-free low-smoke or silica gel material.
Described insulation crust is made up of mineral fibres.
The utility model patent compared with the existing technology, its advantage is: the construction of cable adopts fire-proof and water-proof insulating barrier, filling explosion-proof lamp, fire-proof and water-proof insulating layer, total screen and external sheath layer sandwich construction parcel conductor to form, rational in infrastructure, can reach explosion-proof, fire prevention, waterproof effect, explosion-proof performance safety and stability; Fire-proof and water-proof insulating layer wherein after ceramic fiber paper back adhesive glass fabric, bonds aluminium foil again form, and refractory temperature is high, and thermal insulation is effective, and quality of materials is light, quality is soft, alleviates the weight of whole cable, make the easy mounting and installation of cable and bend, convenient transportation; The material that each layer adopts is all ep-type material, and clean environment firendly is nontoxic, meet national environmental protection policy.
