Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model；
In figure: mixed conductor 1, insulating barrier 2, outer jacket 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of positive square cable of mixed conductor resistant environmental low-smoke halogen-free flame, comprise mixed conductor 1, insulating barrier 2 and outer jacket 3, described mixed conductor 1 comprises tinned copper wire and tin-coated copper plated aluminium B alloy wire, the quantity of tinned copper wire is more than one, it is arranged on outer layer, the quantity of tin-coated copper plated aluminium B alloy wire is more than one, it is arranged on internal layer, the two bundle strand is arranged, the material of insulating barrier 2 is flame-retardant low-smoke halogen-free polyolefine material, extrusion is coated on the outside of mixed conductor 1, insulated wire cores is formed with mixed conductor 1, the material of outer jacket 3 is flame-retardant low-smoke halogen-free polyolefine material, extrusion is coated on the outside of insulated wire cores.
The quantity of the mixed conductor 1 that each insulating barrier 2 is coated with is three strands.
The quantity of the insulated wire cores that each outer jacket 3 is coated with is two.
Conductor have employed the mode of copper wire and aluminum-alloy wire mixing as conductor.The resistivity of 20 DEG C of aluminum-alloy wires is 0.0268 Ω .mm2/ m, and the specific insulation of copper is 0.017241 Ω .mm2/ m, 1.5 aluminum-alloy wires can substitute 1 copper wire as conductor in theory.
Percentage elongation >=8% of aluminum-alloy wire, percentage elongation >=15% of copper wire, during synnema, aluminum-alloy wire is placed on internal layer, copper wire, completely can not fracture of wire at outer layer, it is achieved aluminum-alloy wire substitutes the possibility of copper wire.
The proportion of aluminum-alloy wire is 3.7 g/cm 3, the proportion of copper wire is 8.89 g/cm 3, the overall weight of cable can be alleviated generally, it is simple to install.
In actual applications, mixed conductor 1 is combined into for many tinned copper wires and tin-coated copper plated aluminium alloy tow, the percentage elongation of aluminum-alloy wire is less than the percentage elongation of copper wire, synnema internal layer subjected to low tension, outer layer is big by tension force, in order to avoid aluminum-alloy wire phenomenon of fracture of wire during synnema, use the synnema mode of unlined aluminium B alloy wire outer layer copper wire, it is achieved the not possibility of fracture of wire.Using three strand extrusion arranged in parallel low smoke halogen-free flame-retardant polyolefin insulation after bundle strand, insulated wire cores is platypelloid type, and two core insulation cores are placed in parallel extrusion low-smoke and halogen-free flame retardant polyolefin jacket again.Insulation and sheath material use resistant environmental low-smoke halogen-free flame polyolefin, it has the low-smoke and flame retardant performance of excellence, can guarantee that cable does not produce toxic gas and not the spreading of flame support in the environment of burning, and there is self-extinguishment, it is ensured that cable safe handling in the combustion environment.Cable has lightweight, low cost of manufacture, environmental protection, fire-retardant advantage on the whole, is the environment-friendly cable that is suitable for of very economical.
