In order to solve the technical problem existed in background technology, the utility model proposes a kind of aviation environment friendly heat resistant fireproof cable, its high current-carrying, lightweight, high temperature resistant excellent fire retarding performance, being suitable for using under aviation aircraft environment.
A kind of aviation environment friendly heat resistant fireproof cable that the utility model proposes, comprises cable core, the wrapped lapping layer in described cable core outside, is coated on the fireprotection layer of lapping layer outside, is coated on the restrictive coating of fireprotection layer outside; Described cable core longitudinally to form by multiple conducting wires is parallel, every root wire comprises the aluminium alloy stay pipe being positioned at middle part, at the outside coated conductor layer be entwined by many tin-coated copper wires of aluminium alloy stay pipe, form ring cross-section, semiconductive shielding layer is extruded in conductor layer outside, the outside extruded insulation layer of semiconductive shielding layer, the outside wrapped metallo-plastic composite band of insulating barrier; Lapping layer adopts the wrapped form of ceramic fibre strip, and restrictive coating adopts low-smoke non-halogen flame-retardant high-strength abrasion-proof elastomer to make.
Preferably, aluminium alloy stay pipe is circular cross-section.
Preferably, metallo-plastic composite band is double-sided aluminum plastic composite band, and be thin aluminium lamination in the middle of it, two sides is polyethylene layer.
Preferably, insulating barrier adopts crosslinked polyethylene to make.
In the utility model, the aviation environment friendly heat resistant fireproof cable proposed, cable core outside is coated lapping layer, fireprotection layer and restrictive coating successively, lapping layer adopts that ceramic fibre strip is wrapped forms, the conductor center of each wire adopts aluminium alloy stay pipe, at the conductor layer that the outside coated multilayer of aluminium alloy stay pipe is entwined by many tin-coated copper wires, and each wire is equipped with semiconductive shielding layer and metallo-plastic composite bed.With the cable of above-mentioned structural allocation, while ensure that the conductive capability of cable, decrease copper material consumption, alleviate the total weight of cable, meanwhile, reduce the possibility of cable breaking out of fire in hot environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of aviation environment friendly heat resistant fireproof cable that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of aviation environment friendly heat resistant fireproof cable that the utility model proposes.
With reference to Fig. 1, a kind of aviation environment friendly heat resistant fireproof cable that the utility model proposes, comprises cable core, lapping layer 2, fireprotection layer 3 and restrictive coating 4;
Described cable core longitudinally to form by three wires 1 are parallel;
Every root wire 1 comprises the aluminium alloy stay pipe 11 being positioned at middle part, and aluminium alloy stay pipe 11 is circular cross-section, at the outside coated conductor layer 12 be entwined by many tin-coated copper wires of aluminium alloy stay pipe 11, forms ring cross-section; Copper conductor is utilized to become skin principle, while ensure that the conductive capability of cable, decrease copper material consumption, alleviate the total weight of cable, and adopt tin-coated copper wire to replace oxygen-free cupreous, solve the problem that oxygen-free cupreous is oxidizable, improve current capacity further, in addition, the heat that during cable work, conductor produces also can dispel the heat from aluminium alloy stay pipe 11 inner space;
Extrude semiconductive shielding layer 13 in conductor layer 12 outside, the outside extruded insulation layer 14 of semiconductive shielding layer 13, the outside wrapped double-sided aluminum plastic composite band 15 of insulating barrier 14, be thin aluminium lamination in the middle of it, two sides is polyethylene layer; Prevent the gap between metal and insulating barrier, ensure metal equipotential and with insulating barrier good contact, thus avoid metal and surface of insulating layer to produce partial discharge, and in semiconductive shielding layer uniform electric field distribution and metal and insulating surface generation corona produce, ensure the stable of cable height current-carrying, in addition, semiconductive shielding layer 13 both provides separated-shielding for every root wire 1 together with the thin aluminium lamination of double-sided aluminum plastic composite band 15, prevents the Electromagnetic Interference with Exterior cable between wire 1;
The outside coated lapping layer 2 of described cable core, lapping layer 2 adopts that ceramic fibre strip is wrapped to be formed, and it is compared with mica tape, and adiabatic fire resistance is good, and conductive coefficient is less, intensity is high simultaneously, and three wires 1 are strapped in together by it, play the effect of thermal insulation layer simultaneously, the outside coated fireprotection layer 3 of lapping layer 2, the outside coated restrictive coating 4 of fireprotection layer 3, restrictive coating 4 adopts low-smoke non-halogen flame-retardant high-strength abrasion-proof elastomer to make, and can improve the fire-resistant needs of tensile wear-resistant sexual satisfaction of the restrictive coating of cable.
