Abstract
The invention discloses a low-smoke halogen-free flame-retardant aluminum alloy variable frequency cable which consists of power wire cores, ground wire cores, low-smoke halogen-free flame-retardant glass fiber ropes, low-smoke halogen-free glass fiber band winding layers, a shielding layer and a low-smoke halogen-free flame-retardant polyolefin outer sheath layer. The power wire cores and the ground wire cores are formed by wrapping flame-retardant crosslinked polyethylene insulating layers on aluminum alloy stranded conductors. Three power wire cores and three ground wire cores are stranded at intervals to form cable cores. Gaps of the cable cores are filled with the low-smoke halogen-free flame-retardant glass fiber ropes, and the low-smoke halogen-free glass fiber band winding layers are arranged outside the cable cores. The low-smoke halogen-free flame-retardant polyolefin outer sheath layer and the shielding layer sequentially cover the low-smoke halogen-free glass fiber band winding layers from outside to inside. The low-smoke halogen-free flame-retardant aluminum alloy variable frequency cable has the advantages of being halogen-free, low-smoke, high in flame retardance and shielding performance and the like.
Description
Technical field
The present invention relates to cable, relate in particular to low-smoke non-halogen flame-retardant aluminium alloy frequency conversion cable.
Background technology
Along with the development of frequency drive technology processed, requirement to frequency variable ratio drive system is more and more higher, especially to adopting the modern converter technique of IGBT semiconductor of quick switching, although pulse frequency is high or more they generate an electromagnetic field to surrounding environment only in millisecond the break time.For keeping frequency converter normal work not to be subject to electromagnetic interference, therefore connect cable between frequency converter and three phase alternating current motor and will there is interference free performance, lower effective capacitance and lower transfer impedance.The features such as this just requires cable to have Halogen, low cigarette, high flame retardant, high shielding.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide low-smoke non-halogen flame-retardant aluminium alloy frequency conversion cable.
The solution of the present invention is as follows: low-smoke non-halogen flame-retardant aluminium alloy frequency conversion cable, it by power core, wire core, low-smoke non-halogen flame-retardant glass fiber rope, low smoke and zero halogen glass fibre belt lapping layer, screen and low smoke halogen-free flame-retardant polyolefin external sheath layer form, described power core and ground wire core are to be all extruded on aluminium alloy stranded conductor and to be formed by flame-retardant crosslinking polyethylene insulated layer; Described three power cores and wire core interval, three ground are twisted into cable core; Described cable core gap-fill has low-smoke non-halogen flame-retardant glass fiber rope, and cable core is provided with low smoke and zero halogen glass fibre belt lapping layer outward; Described low smoke halogen-free flame-retardant polyolefin external sheath layer and screen cover on low smoke and zero halogen glass fibre belt lapping layer successively from outside to inside.
Described screen adopts proof copper-wire braided and copper strips is wrapped combines.
Beneficial effect of the present invention: cable of the present invention has Halogen, low cigarette, high flame retardant, the features such as high shielding.
Brief description of the drawings
Fig. 1 is structural representation of the present invention,
Wherein: 1, power core; 2, aluminium alloy stranded conductor; 3, flame-retardant crosslinking polyethylene insulated layer; 4, wire core; 5, low-smoke non-halogen flame-retardant glass fiber rope; 6, low smoke and zero halogen glass fibre belt lapping layer; 7, screen; 8, low smoke halogen-free flame-retardant polyolefin external sheath layer.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described;
As shown in Figure 1, low-smoke non-halogen flame-retardant aluminium alloy frequency conversion cable, it by power core 1, wire core 4, low-smoke non-halogen flame-retardant glass fiber rope 5, low smoke and zero halogen glass fibre belt lapping layer 6, screen 7 and low smoke halogen-free flame-retardant polyolefin external sheath layer 8 form, described power core 1 and ground wire core 4 are to be all extruded on aluminium alloy stranded conductor 2 and to be formed by flame-retardant crosslinking polyethylene insulated layer 3; Described three power cores 1 and wire core 4 intervals, three ground are twisted into cable core; Described cable core gap-fill has low-smoke non-halogen flame-retardant glass fiber rope 5, and cable core is provided with low smoke and zero halogen glass fibre belt lapping layer 6 outward; Described low smoke halogen-free flame-retardant polyolefin external sheath layer 8 and screen 7 cover on low smoke and zero halogen glass fibre belt lapping layer 6 successively from outside to inside.
Described screen 7 adopts proof copper-wire braided and copper strips is wrapped combines.
The conductor of power core 1 and ground wire core 4 forms by aluminium alloy conductor is stranded, make the bending radius of cable more much smaller than copper core cable, more easily lay, insulating barrier all adopts cross-linking polyethylene materials, it has excellent electric property, and there is flame-retarding characteristic, screen 7 can effectively suppress the electromagnetic interference on inside and outside boundary, and conveyer, transmission line and all kinds of compression pump, the air blast, the central air conditioning etc. that are particularly useful for the automatic production line of iron and steel, petrochemical industry, power plant, papermaking, weaving, metal processing and food processing are connected use.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
