The aluminium alloy flame-retardant frequency variable cable has advantages of being simple in structure design, being stable in performance, being capable of fulfilling performance requirements of high-temperature-resistant and flame-retardant cables, being easy to lay due to the flexibility of the cable, being capable of preventing squeezing deformation between the cable cores, and being capable of discharging leakage electricity through the current guiding line.
Description
Technical field
The utility model relates to cable, relates in particular to the fire-retardant frequency-changing cable of aluminium alloy.
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.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide the fire-retardant frequency-changing cable of aluminium alloy.
Scheme of the present utility model is as follows: the fire-retardant frequency-changing cable of aluminium alloy, it by power core, wire core, fire-retardant gasket for packing, glass fibre belt lapping layer, screen and flame-proof polyvinyl chloride 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; In the middle of described three power cores, be extruded with foam filled layer; Every two power cores and one ground wire core is provided with drainage thread in stranded gap; Described cable core gap-fill has fire-retardant gasket for packing, and cable core is provided with glass fibre belt lapping layer outward; Described flame-proof polyvinyl chloride external sheath layer and screen cover on glass fibre belt lapping layer successively from outside to inside.
Described screen adopts proof copper-wire braided and copper strips is wrapped combines.
The beneficial effects of the utility model: the utility model structural design is simple, stable performance, can meet high temperature resistant and performance requirement flame retardant cable, and cable softness is easy to lay, and more can prevent the crimp between core, can discharge electric leakage by drainage thread.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Wherein: 1, power core; 2, aluminium alloy stranded conductor; 3, flame-retardant crosslinking polyethylene insulated layer; 4, wire core; 5, fire-retardant gasket for packing; 6, glass fibre belt lapping layer; 7, screen; 8, flame-proof polyvinyl chloride external sheath layer; 9, foam filled layer; 10, drainage thread.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, the fire-retardant frequency-changing cable of aluminium alloy, it by power core 1, wire core 4, fire-retardant gasket for packing 5, glass fibre belt lapping layer 6, screen 7 and flame-proof polyvinyl chloride 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; In the middle of described three power cores 1, be extruded with foam filled layer 9; Every two power cores 1 and one ground wire core 4 is provided with drainage thread 10 in stranded gap; Described cable core gap-fill has fire-retardant gasket for packing 5, and cable core is provided with glass fibre belt lapping layer 6 outward; Described flame-proof polyvinyl chloride external sheath layer 8 and screen 7 cover on 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, in addition the structural behaviour of the symmetrical core band shielding of 3+3 is best, adopt symmetrical shielded type cable also can reduce the electromagnetic radiation of drive system, and reduce the shaft current of motor and the bearing wear causing thus.Flame-proof polyvinyl chloride external sheath layer 8, plays a protective role to cable, heat insulation, oxygen barrier effect; And foam filled layer 9 more can prevent the crimp between core, can discharge electric leakage by drainage thread 10.
Although above embodiment of the present utility model 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 utility model and change and amendment; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
