Abstract
The utility model discloses a mouse prevention, fireproof, flame-retardant and double-shielding cable. The cable comprises a plurality of conductors. A composite fireproof layer, an insulating layer and a copper wire braided sub-shielding layer are successively wrapped outside each conductor, such that insulating cores are formed. Each composite fireproof layer successively includes, from inside to outside, a mica tape, a fireproof inorganic short fiber viscose glue layer and a taped layer. The insulating cores are intertwisted to form a cable core. A glass fiber tape is wrapped outside the cable core, a copper belt main shielding layer, a nylon protective layer and a sheath layer are successively wrapped outside the glass fiber tape, and a filling layer is disposed between the cable core and the glass fiber tape. The cable of the utility model has a simple structure, exhibits good fireproof and shielding properties, is effectively guaranteed to be safe to use when being burnt at high temperature, is prevented from being bitten by mice and is prolonged in terms of the service life.
Description
Technical field
The utility model relates to the electric wire field, is specially a kind of protection against rodents fire resistant flame retardant screened cable.
Background technology
Along with the fast development of power industry, urban construction, all trades and professions are more and more higher to the requirement of cable.The employing that traditional cable is more the structure of thermal insulation difference, not flame resistant calcination.Therefore; when breaking out of fire; the not flame resistant baking of this class cable is difficult to isolated flame, so flame these protective layers that are easy to ablate; make cable directly be subjected to the calcination of flame; cause cable can not work, shortened the useful life of cable, and common cable is bitten by mouse easily and has potential safety hazard because of short circuit; shielding properties is not good, and result of use is relatively poor under the complex work environment.
The utility model content
The purpose of this utility model provides a kind of protection against rodents fire resistant flame retardant screened cable, not good to solve cable fire resistance and shielding properties traditional in the prior art, cause cable short circuit easily and cisco unity malfunction when being subjected to the flame calcination, bitten by mouse easily, useful life is shorter, the relatively poor problem of result of use under the complex work environment.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of protection against rodents fire resistant flame retardant screened cable, include the array conductor, it is characterized in that: every group of conductor all is coated with composite fire layer, insulating barrier and copper wire braiding sub-shield outward successively, and formation insulated wire cores, described composite fire layer is followed successively by mica tape, fire-resistant inorganic short fiber adhesive-layer and lapping layer from inside to outside, the stranded formation cable core of several insulated wire cores, described cable core is coated with glass fiber tape, described glass fiber tape is coated with the total screen of copper strips, nylon overcoat and restrictive coating outward successively, is provided with packed layer between described cable core and the glass fiber tape.
Described a kind of protection against rodents fire resistant flame retardant screened cable is characterized in that: described conductor is zinc-plated soft copper conductor.
Described a kind of protection against rodents fire resistant flame retardant screened cable is characterized in that: described fire-resistant inorganic short fiber adhesive-layer adopts polycrystal alumina or polycrystalline mullite short fiber to make.
Described a kind of protection against rodents fire resistant flame retardant screened cable is characterized in that: described restrictive coating adopts acrylonitrile-butadiene rubber to make.
The beneficial effects of the utility model are:
The utility model is simple in structure, adopt the design of composite fire layer and glass fiber tape,, promoted the fire resistance of cable effectively for cable provides double-deck refractory protection, guarantee cable safe in utilization when being subjected to high temperature sintering, prolonged useful life of cable; Adopt the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of mouse; Adopt the double layer screen design of copper wire braiding sub-shield and the total screen of copper strips, promoted the shielding properties of cable effectively, guaranteed the result of use of cable under the complex work environment.
