Abstract
The invention relates to a halogen-free low-smoke flame-retardant cable. The halogen-free low-smoke flame-retardant cable comprises three groups of cores which are formed by conductors and insulating layers through extrusion, a lapping layer, an inner sheath layer, an outer sheath layer and an armor layer. The halogen-free low-smoke flame-retardant cable is characterized in that the external parts of the conductors are further wrapped with flame-retardant isolating layers; aluminum silicate filling layers are further arranged at gaps between the lapping layer and the cores. By adopting multiple strengthening measures such as fire prevention through mica tapes, flame retardation through glass fiber woven tapes and insulation through halogen-free cross-linked polyethylene, the demands of people for low smoke, no halogen and environmental friendliness can be effectively satisfied.
Description
Technical field
The present invention relates to field of cables, be specifically related to a kind of halide-free low-smoke fireproof cable.
Background technology
Traditional cable insulation adopts polyvinyl chloride to make mostly, this type of material has good mechanical strength and insulating properties, but it is poor to the stability of light and heat, Contact Temperature reaches 100 DEG C just can decompose generation hydrogen chloride, physical and mechanical properties also can decline rapidly, when fire occurs, poly (vinyl chloride) blend is heated and easily decomposites a large amount of hydrogen chloride, produce a large amount of dense smoke, bring very large difficulty to the escape of people and fire-fighting and rescue work, and the halogen element given out during polyvinyl chloride burning more there is fatal harm.
Summary of the invention
The present invention will provide the ECO of a kind of low smoke and zero halogen, wear-resisting and stress crack resistant.
Technical scheme of the present invention is as follows:
For solving the problems of the technologies described above, halide-free low-smoke fireproof cable of the present invention it comprise conductor and extrude three groups of cores, lapping layer, inner restrictive coating, external sheath layer and armours of formation with insulating barrier, it is characterized by: described conductor is also coated with fire-resistant separator outward; Between described lapping layer and core, gap is also provided with alumina silicate packed layer.
Described fire-resistant separator adopts mica tape or magnesia powder.
Described lapping layer adopts woven fiberglass tape.
Described insulating barrier adopts cross-linking polyethylene materials.
Described inner restrictive coating adopts polyolefine material.
Beneficial effect: the present invention's multiple enhancements such as adopt mica tape or magnesia powder fire prevention, the fire-retardant and Halogen of woven fiberglass tape crosslinked polyetylene insulated, effectively can meet the demand of people for cable low smoke and zero halogen, environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, conductor 2, insulating barrier 3, fire-resistant separator 4, lapping layer 5, inner restrictive coating 6, external sheath layer 7, armour 8, alumina silicate packed layer
Embodiment
Its structure as shown in Figure 1: a kind of halide-free low-smoke fireproof cable it comprise conductor 1 and extrude three groups of cores of formation, lapping layer 4, inner restrictive coating 6, external sheath layer 7 and armour 8 with insulating barrier 2; Described conductor 1 is outer is also coated with fire-resistant separator 3; Between described lapping layer 4 and core, gap is also provided with alumina silicate packed layer 8; Described fire-resistant separator 3 adopts mica tape; Described lapping layer 4 adopts woven fiberglass tape; Described insulating barrier 2 adopts cross-linking polyethylene materials; Described inner restrictive coating 4 adopts polyolefine material.
The present invention adopts the multiple enhancements such as mica tape is prevented fires, the fire-retardant and Halogen of woven fiberglass tape is crosslinked polyetylene insulated, effectively can meet the demand of people for cable low smoke and zero halogen, environmental protection.
