Abstract
The invention discloses an environment-friendly cable and relates to the field of wires and cables. The environment-friendly cable comprises a plurality of cable cores (1), fillers (2), a polyolefin inner sheath (3) and a polyolefin outer sheath (4), wherein each cable core (1) comprises a conductor (1-1), an isolation layer (1-2) and an insulation layer (1-3), and the isolation layer (1-2) and the insulation layer (1-3) are arranged on the outer side of the conductor (1-1) in sequence. The cable cores (1) are connected into the polyolefin inner sheath (3) in a twisted mode, the fillers (2) are arranged in gaps in the polyolefin inner sheath (3), and the polyolefin outer sheath (4) is arranged on the outer side of the polyolefin inner sheath (3). The environment-friendly cable overcomes the shortcomings in the prior art. The inner sheath and the outer sheath are made from polyolefin, therefore, discarded cables can be recycled or buried and burned, and no pollution to the environment is caused.
Description
Technical field:
The present invention relates to a kind of electric wire and cable material, be specifically related to a kind of environment-friendly cable.
Background technology:
Along with social development, and people constantly increase the demand of electric power, also more and more as the demand of the electric wire of electric power transfer main carriers.The most important electric property of electric wire is that realization decay is low, impedance is even, return loss is high, most important mechanical performance is bending property (especially under low temperature), tensile strength, compression strength and anti-wear performance, the environmental stress during electric wire also should be able to bear transportation, storage, installs and use.If electric wire is arranged on the high place of fire safety requirement, its fire protecting performance is also very important, and wherein three most important factors are: flame-retarding power, smoke density and halogen gas burst size.
Formal execution along with the RoHS of European Union standard, and the domestic continuous reinforcement to environmental consciousness, exploitation environment-friendly type wire products become trend of the times, therefore, for meeting the continuous demand in market, when keeping the original performance of product and cost, producing the wire products that reach environmental protection standard is brand new technical fields anxious to be developed.
In cable, mostly adopt now pvc material to make insulating barrier and the restrictive coating of cable, contain the noxious substances such as lead, cadmium, mercury in polyvinyl chloride, these materials have all produced serious pollution to nature, are not suitable for a large amount of production.
Summary of the invention:
The object of this invention is to provide a kind of environment-friendly cable, it can overcome the drawback of prior art, adopts polyolefin to make inner sheath and oversheath, can recycling after cable is discarded or do not bury, burn and can produce harm to environment.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises cable core 1, filler 2, polyolefin inner sheath 3, polyolefin oversheath 4, cable core 1 comprises conductor 1-1, separator 1-2 and insulating barrier 1-3, the outside of conductor 1-1 is disposed with separator 1-2 and insulating barrier 1-3, several cable core 1 hinge joints are arranged in polyolefin inner sheath 3, in space in polyolefin inner sheath 3, be provided with filler 2, the arranged outside of polyolefin inner sheath 3 has polyolefin oversheath 4.
Described separator 1-2 is compound nonwoven cloth separator.
Described insulating barrier 1-3 is crosslinked polyetylene insulated layer.
Described polyolefin inner sheath 3 and polyolefin oversheath 4 adopts polyethylene, polypropylene and polyolefin blend to make, and it has, and transparency is high, good insulating, good corrosion resistance, and the advantage such as environmental and durable.
The present invention can overcome the drawback of prior art, adopts polyolefin to make inner sheath and oversheath, can recycling after cable is discarded or do not bury, burn and can produce harm to environment.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises cable core 1, filler 2, polyolefin inner sheath 3, polyolefin oversheath 4, cable core 1 comprises conductor 1-1, separator 1-2 and insulating barrier 1-3, the outside of conductor 1-1 is disposed with separator 1-2 and insulating barrier 1-3, several cable core 1 hinge joints are arranged in polyolefin inner sheath 3, in space in polyolefin inner sheath 3, be provided with filler 2, the arranged outside of polyolefin inner sheath 3 has polyolefin oversheath 4.
Described separator 1-2 is compound nonwoven cloth separator.
Described insulating barrier 1-3 is crosslinked polyetylene insulated layer.
Described polyolefin inner sheath 3 and polyolefin oversheath 4 adopts polyethylene, polypropylene and polyolefin blend to make, and it has, and transparency is high, good insulating, good corrosion resistance, and the advantage such as environmental and durable.
This embodiment can overcome the drawback of prior art, adopts polyolefin to make inner sheath and oversheath, can recycling after cable is discarded or do not bury, burn and can produce harm to environment.
