Abstract

The utility model discloses a bend-resistant tensile heat-resisting variable frequency cable, comprising conductors, insulators, filler, a wrapping tape layer, an inner sheath, a reinforcing layer, and an outer sheath. The conductors use a bunch strand structure. Fiber reinforcing components are added in the center of the conductors. The insulators are extruded on the conductors, and a method of continuous vulcanization is used. Then, six insulating wire cores are stranded together by relatively a small pitch, and meanwhile the filler and the wrapping tape layer are added. The wire cores are extruded with the inner sheath in sequence. On the inner sheath, the reinforcing layer is woven using steel wires/fibers by a braiding machine. The outer sheath is extruded outside the reinforcing layer. The cable is stable in structure, has relatively good voltage resistance impact property, and has good protection effect on frequency conversion electric appliances, and meanwhile the cable has good tensile and bend-resistant properties. Cable laying is very easy, and is characterized by high temperature resistance, low temperature resistance, radiation resistance, and ozone resistance.

Description

The heat-resisting frequency-changing cable of a kind of anti-resisting bending tension

Technical field

The utility model relates to field of cables, relates in particular to the heat-resisting frequency-changing cable of a kind of anti-resisting bending tension.

Background technology

At present, according to statistics, come frequency control motor that very big development is arranged at home and abroad at recent two decades, annual growth slightly surpasses 10%, and the DC Transmission annual growth is 3-4%.Variable-frequency motor has more advantage, and few as the equipment investment expense, simple in structure, volume is little, and cost is low, and is energy-conservation, and speed adjustable range is big, has the characteristic of permanent power, permanent rotating speed, and is easy to use, and capacity is big etc.Therefore currently use widely in industrial aspect such as metallurgy, mine, railways, equally also widely apply at household electrical appliance recently.

Summary of the invention

In order to overcome the defective of above-mentioned prior art, the purpose of this utility model provides a kind of the utility model Stability Analysis of Structures, has the heat-resisting frequency-changing cable of anti-resisting bending tension of stronger proof voltage impact.

The utility model takes following technical scheme to realize: the heat-resisting frequency-changing cable of a kind of anti-resisting bending tension is made up of conductor, insulation, obturator, belting layer, inner sheath, reinforced layer and oversheath.Described conductor adopts restraints the structure that tangles, add the fiber reinforcing element at described conductor center, described insulation is extruded on the described conductor, and employing continuous vulcanization, six roots of sensation insulated wire cores twists together with less pitch then, adds described obturator and described belting layer simultaneously, is extruded with described inner sheath successively, carry out steel wire/fibrage with braiding machine and become described reinforced layer on described inner sheath, described reinforced layer is extruded with described oversheath outward.

Described conductor adopts high tensile strength fibrous material as reinforcing element.

The utlity model has following beneficial effect in sum:

1, has stronger proof voltage impact, frequency conversion electrical equipment is played a good protection;

2, while cable tension good bending property is very easily laid;

3, have high temperature resistant, low temperature resistant, radiation hardness and ozone proof characteristics.

Wherein: 1, conductor; 2, insulation; 3, obturator; 4, belting layer; 5, inner sheath; 6, reinforced layer; 7, oversheath.

Embodiment

As shown in Figure 1, the heat-resisting frequency-changing cable of a kind of anti-resisting bending tension is made up of conductor 1, insulation 2, obturator 3, belting layer 4, inner sheath 5, reinforced layer 6 and oversheath 7.Described conductor 1 adopts restraints the structure that tangles, add the fiber reinforcing element at described conductor 1 center, described insulation 2 is extruded on the described conductor 1, and employing continuous vulcanization, six roots of sensation insulated wire cores twists together with less pitch then, adds described obturator 3 and described belting layer 4 simultaneously, is extruded with described inner sheath 5 then, on described inner sheath 5, carry out steel wire/fibrage with braiding machine and become described reinforced layer 6, be extruded with described oversheath 7 outside the described reinforced layer 6.

In concrete the enforcement: conductor 1 adopts high tensile strength fibrous material as reinforcing element.

It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail with reference to above-mentioned the utility model of each embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
