Technical field
The utility model relates to a kind of cable, particularly relates to a kind of resistant environmental low-smoke halogen-free flame cable, belongs to technical field of electric wires and cables.
Background technology
Along with the fast development of urban construction, high-rise building covers higher and higher, also day by day harsh to the requirement of electric equipment, and electric wire is generally economic construction just as the blood vessel of people and carries electric power energy and various information signal resource from all directions.But, fire in recent years owing to electrically causing increases gradually, and the fire wherein caused due to electric wire reason occupies sizable ratio, therefore fire-retardant and fire prevention becomes the important indicator of cable performance, how to improve fireproofing of cable fire resistance and seems particularly important.
Along with the progress of science and technology, gasket for packing is as one of important component part of filling electric wire, become important scientific and technological development project, day by day be subject in the industry and the concern of relevant industries, existing cable filling layer adopts asbestos and glass fibre as flame resistant filler material mostly, but above-mentioned material can cause flying dust to fly upward in cable uses, and enters respiratory tract and forms deposition, harmful, and contaminated environment is not environmentally.In addition existing cable insulation material temperature resistant grade only can reach 90 DEG C, and anti-overload ability is not strong.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of environmental protection, and fire-retardant, temperature resistant grade is high, the resistant environmental low-smoke halogen-free flame cable that anti-overload ability is strong.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of resistant environmental low-smoke halogen-free flame cable, comprise cable conductor, insulating barrier is arranged with outside described cable conductor, the cable conductor of more than three or three with insulating barrier is twisted into bunch of cables, the outside of described bunch of cables flame resistant filler layer successively from inside to outside, coating layer and restrictive coating, environment-friendly high-temperature flame resistant filler rope is filled with in described flame resistant filler layer, described coating layer adopts the resistant environmental low-smoke halogen-free flame band coiling of more than three layers to form, described insulating barrier adopts the composite construction combined by inner insulating layer and insulating outer layer, described inner insulating layer adopts environment-friendly type 105 DEG C of IXPE materials, described insulating outer layer adopts environment-friendly type 105 DEG C of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin materials.
Described restrictive coating adopts 105 DEG C of resistant environmental low-smoke halogen-free flame polyolefine materials, further increases the environmental protection of cable, fire resistance.
The beneficial effects of the utility model are: be filled with environment-friendly high-temperature flame resistant filler rope in flame resistant filler layer, further enhance the fire-retardant fireproof performance of cable, cable adopts environment-friendly high-temperature flame resistant filler rope and insulated compound structure fire resistant flame retardant structure from inside to outside, the fire-retardant fireproof performance of whole cable is promoted greatly, fire protection flame retarding designs, high temperature resistant, Stability Analysis of Structures, effect is very good, described bunch of cables adopts the coating layer of high-fire-resistance packed layer and fire-retardant band outward, make cable outward appearance rounding, improve cable-flame retardant performance; Insulating barrier adopts composite construction, the co-extrusion while of two-layer, ensures in conjunction with tight gapless; Described inner insulating layer adopts environment-friendly type 105 DEG C of IXPE materials, and described insulating outer layer adopts environment-friendly type 105 DEG C of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin materials.Electron accelerator is adopted to carry out radiation irradiation to insulating material, by the modification of crosslinking with radiation to insulating material, improve mechanical performance, the ageing-resistant performance of cable insulation, temperature resistant grade reaches 105 DEG C, the lifting of cable temperature resistant grade makes the ampacity of cable compare common low-smoke halogen-free inflaming-retarding cable and improves 10%-15%, and the anti-overload ability of cable is strong.

Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of resistant environmental low-smoke halogen-free flame cable, comprise cable conductor 6, insulating barrier is arranged with outside described cable conductor 6, the cable conductor of more than three or three with insulating barrier is twisted into bunch of cables, the outside of described bunch of cables flame resistant filler layer 3 successively from inside to outside, coating layer 2 and restrictive coating 1, environment-friendly high-temperature flame resistant filler rope is filled with in described flame resistant filler layer 3, described coating layer 2 adopts the resistant environmental low-smoke halogen-free flame band coiling of more than three layers to form, described insulating barrier adopts the composite construction combined by inner insulating layer 5 and insulating outer layer 4, described inner insulating layer adopts environment-friendly type 105 DEG C of IXPE materials, described insulating outer layer adopts environment-friendly type 105 DEG C of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin materials.
Described restrictive coating 1 adopts 105 DEG C of resistant environmental low-smoke halogen-free flame polyolefine materials, further increases the environmental protection of cable, fire resistance.
Described environment-friendly high-temperature flame resistant filler rope comprise rope body and dipping, coated rope body environmental protection fire retarding agent.Concrete rope body adopts high temperature resistant cotton yarn to become sub-thread rope form by mechanical entanglement, then single cord is flooded, the certain thickness flame-retardant layer of coated, then be stranding into the environmental protection flame retardant gasket for packing of various outer diameter of cable filling as required.By adopting this gasket for packing, making that whole cable is soft, lightweight, the harmful substance such as intensity is large, not halogen-containing, asbestos, glass fibre, meeting European Union ROHS standard-required.
Described coating layer adopts more than three layers resistant environmental low-smoke halogen-free flame bands to put up coiling and forms, and forms a fine and close fire-retardant oxygen barrier layer.Make cable when fire occurs, this coating layer forms an airtight housing, stops oxygen to enter cable core inside, reduces the damaged condition of insulation.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
