Abstract
The utility model discloses a rat-and-ant-proof environment-friendly power cable, which comprises three conductors. A tensile rope braided by aramid fibers is arranged in each of the three conductors, each conductor is wrapped in a low-smoke halogen-free insulating layer to form an insulating core, and the three insulating cores are arranged in the form of triangle. A thickening layer is arranged outside the three insulating cores, a buffer layer molded by plastic extrusion of thermoplastic elastomers is arranged outside the thickening layer, a high-intensity carbon tube is arranged outside the buffer layer, a crosslinked polyolefin oversheath layer is arranged outside the high-intensity carbon tube, and a steel band is arranged in the crosslinked polyolefin oversheath layer. The rat-and-ant-proof environment-friendly power cable is reasonable in structural design, wherein the buffer layer, the high-intensity carbon tube and the steel band in the oversheath layer effectively resist external extrusion and damages by the rat and ant, and the thickening layer and the low-smoke halogen-free insulating layers enable the cable to have good high temperature resistance and fireproof performance and have no environmental pollution.
Description
Technical field:
The utility model relates to power cable, relates in particular to a kind of protection against rodents ant and environment-friendly type power cable.
Background technology:
Power cable is applicable to that electric pressure is in 0.6/1kv and following power transmission and distribution system, usefulness for the transmission ﹠ distribution electric energy, be widely used in departments such as electric power, building, industrial and mineral, petrochemical industry, traffic, along with environmental protection is more and more paid attention to by people, so the low smoke and zero halogen environment-friendly cable is more and more paid attention to.
Original construction of cable design is reasonable inadequately, and it is impaired easily to be subjected to extraneous extruding cable core, simultaneously the mouse ant is stung the damage resistance and does not reach the real work demand, influences electric power transfer.
The utility model content:
For remedying the defective of prior art, the purpose of this utility model provides a kind of protection against rodents ant and environment-friendly type power cable, can guarantee that being out of shape does not appear in cable core or the phenomenon of disconnected core, can defend the mouse ant to sting damage well simultaneously.
The technical solution of the utility model is as follows:
Protection against rodents ant and environment-friendly type power cable, comprise three conductors, it is characterized in that: be equipped with the aramid fiber silk in described three conductors and be woven into funicular tension rope, described three conductors are coated with the low smoke and zero halogen insulating barrier outward respectively and form insulated wire cores, insulated wire cores is arranged in a triangle and is provided with thickening layer in the outside and constitutes cable core, thickening layer is provided with the resilient coating of thermoplastic elastomer (TPE) extrusion moulding outward, resilient coating is provided with the plain pipe of high strength carbon outward, high strength carbon element pipe is provided with the cross-linked polyolefin external sheath layer outward, also is provided with steel band in the cross-linked polyolefin external sheath layer.
Described protection against rodents ant and environment-friendly type power cable is characterized in that: the thickness of described resilient coating is not less than 1.25mm.
Described protection against rodents ant and environment-friendly type power cable is characterized in that: described cross-linked polyolefin external sheath layer also is provided with corrosion-inhibiting coating outward, and the thickness of corrosion-inhibiting coating is not less than 0.8mm.
The utility model has the advantages that:
The utility model reasonable in design, by designing the steel band in resilient coating and high strength carbon element pipe, the restrictive coating, effectively extraneous extruding of opposing and mouse ant damage performance improve, simultaneously, thickening layer and low smoke and zero halogen insulating barrier make cable have high temperature resistant well and fire resistance, and environmentally safe.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Protection against rodents ant and environment-friendly type power cable, comprise three conductors 1, be equipped with the aramid fiber silk in three conductors 1 and be woven into funicular tension rope 2, three conductor 1 outer low smoke and zero halogen insulating barriers 3 that are coated with respectively form insulated wire cores, insulated wire cores is arranged in a triangle and is provided with thickening layer 4 in the outside and constitutes cable core, thickening layer 4 adopts the overlapping wrapped formation of high temperature resistant nonwoven fabrics, the thickening layer 4 outer resilient coatings 5 that are provided with the thermoplastic elastomer (TPE) extrusion moulding, the resilient coating 5 outer plain pipes 6 of high strength carbon that are provided with, be provided with cross-linked polyolefin external sheath layer 7 outside the high strength carbon element pipe 6, also be provided with steel band 8 in the cross-linked polyolefin external sheath layer 7.
The thickness of resilient coating 5 is not less than 1.25mm, can effectively alleviate the extraneous damage that causes distortion even disconnected core to cable conductor of pushing, and influences the transmission of cable to electric power or information.
Also be provided with corrosion-inhibiting coating 9 outside the cross-linked polyolefin external sheath layer 7, the thickness of corrosion-inhibiting coating 9 is not less than 0.8mm, and in a humid environment, corrosion resistance is strong.
