Abstract
The present invention provides an industrial cable. The industrial cable comprises more than one baseline. Each baseline includes a copper conducting core wire (1); the exterior of the copper conducting core wire (1) is provided with a silver tin layer (2); the exterior of the silver tin layer is provided with an insulation cladding (3); a cable filling part is arranged between more than one baseline; the insulation cladding (3) is composed of polyvinyl chloride and TPEE composite materials; and the cable filling part (4) is constituted by two parts, one part thereof is a mixture consisting of talcum powder, modified kaolin clay and Mg(OH)2, wherein the mass ratio of the talcum powder, the modified kaolin clay and the Mg(OH)2 is 3:7:(7-10), and the other part thereof is cellosilk, wherein the weight ratio of the mixture and the cellosilk is 1:2. According to the invention, the performances of wires such as water resistance, flame retardation, aging resistance and the like may be greatly improved.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of industrial cable.
Background technology
The ageing-resistant ability of cable of the prior art is poor, and through the place of field natural exposing or bad environments, long-time use there will be fatigue state, thus causes the aging fracture of electric wire, there is the electric shock risk of industrial operation personnel.
In addition, mostly traditional electric wire is single-core line, and its inside does not have traction element and heat absorbing part.Therefore material is along with meeting quick aging service life, and is easy to destroy internal structure, causes the fracture of internal core.
Summary of the invention
In order to reach as above object, the present invention takes following technical scheme: comprise more than one baseline, described baseline comprises copper and leads heart yearn (1), described copper leads heart yearn (1) outside silver-colored tin layers (2), there is insulated cladding (3) described silver-colored tin layers outside, comprise cable filling portion (4) between described more than one baseline, described more than one baseline outside is surrounded by skin (5);
Described skin (5) is for containing Sb
2o
3with CaCO
3the TPU of filler paints line layer;
Described insulated cladding (3) polyvinyl chloride and TPEE composite material form;
Described cable filling portion (4) is made up of two parts, and wherein a part is mixture, and this mixture is talcum powder, modified kaolin and Mg (OH)
2mixture, wherein talcum powder, modified kaolin and Mg (OH)
2mass ratio be 3:7:(7-10), another part is filament, and described mixture and filametntary weight ratio are 1:2;
Described cable filling portion (4) is filament or fire-retardant, heat absorption material;
Described more than one baseline is concentric circles arrangement;
Described filament is more than one, itself and baseline close contact;
Spacing is identical each other for described more than one baseline;
Described copper leads the cross section of the silver-colored tin layers (2) of heart yearn (1) and outside for circular.
Adopt the present invention of as above technical scheme, have following beneficial effect relative to prior art: power line and holding wire can be used as, therefore act on various, can not the heart yearn of damaging internal, and can efficiently radiates heat.
Accompanying drawing explanation
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
Fig. 1 is the cross section structure schematic diagram of invention;
Wherein: 1. copper leads heart yearn; 2. silver tin layers; 3. insulated cladding; 4. cable filling portion; 5. outer.
Embodiment
Be described embodiments of the invention below in conjunction with accompanying drawing, embodiment is not construed as limiting the invention:
A kind of industrial cable, comprise more than one baseline, described baseline comprises copper and leads heart yearn 1, described copper leads heart yearn 1 outside silver-colored tin layers 2, there is insulated cladding 3 described silver-colored tin layers outside, comprises cable filling portion 4 between described more than one baseline, and described more than one baseline outside is surrounded by outer 5;
Described outer 5 for containing Sb
2o
3with CaCO
3the TPU of filler paints line layer;
Described insulated cladding 3 polyvinyl chloride and TPEE composite material form;
Described cable filling portion 4 is made up of two parts, and wherein a part is mixture, and this mixture is talcum powder, modified kaolin and Mg (OH)
2mixture, wherein talcum powder, modified kaolin and Mg (OH)
2mass ratio be 3:7:(7-10), another part is filament, and described mixture and filametntary weight ratio are 1:2.
Described cable filling portion comprises filament, therefore easy tractive, and the resistance between above structure baseline is out 500 megaohms.Above more than one baseline color each other can be different.Described cable filling portion is fire-retardant, heat absorption material.Therefore can absorb heat, prevent heat from too much gathering in heart yearn inside.It can also be high temperature resistant material.Described more than one baseline is concentric circles arrangement.Therefore compact conformation, there will not be the intertexture of the heart yearn in traction process.
Described filament is more than one, itself and baseline close contact.
Spacing is identical each other for described more than one baseline.Therefore heat can transmit evenly, there will not be the phenomenon that local temperature is too high.
Described copper leads the cross section of the silver-colored tin layers 2 of heart yearn 1 and outside for circular.Because the line of circle has good conducting power.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.Those skilled in the art should understand the present invention and not be restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed scope.
