Abstract
The utility model discloses a fire-resistant flame retardant tensile shielded cable which comprises multiple groups of conductors. Each group of conductors is sequentially coated with a composite fire-resistant layer and an insulating layer, and an insulating wire core is formed. The composite fire-resistant layer comprises a mica tape, a fire-resistant inorganic short fiber adhesive layer and a wrapping layer sequentially from inside to outside. A plurality of insulating wire cores and reinforcing steel cores are stranded to form a cable core which is coated by a glass fiber tape which is orderly coated by a copper wire braid shielding layer and a sheath layer. A filling layer and a layer of steel piece are arranged between the cable core and the glass fiber tape. The surface of the steel piece is painted with waterproof paint and insulating paint. The fire-resistant flame retardant tensile shielded cable has the advantages of simple structure, good fire-resistant performance, good shielding performance and good tensile ability, the safe use of the cable in high temperature burning is ensured, the service life of the cable is prolonged, and the use effect of the cable in a complex work environment is ensured.
Description
Technical field
The utility model relates to the electric wire field, is specially a kind of fire resistant flame retardant tension shielding 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 poor structure of thermal insulation, not flame resistant calcination.Therefore; when breaking out of fire; the not flame resistant baking of this class cable; be difficult to isolated flame, so flame is easy to these protective layers of ablation, makes cable directly be subject to the calcination of flame; cause cable can not work because of short circuit; shortened the useful life of cable, and the shielding properties of common cable and tensile property not good, result of use is relatively poor under the complex work environment.
The utility model content
The purpose of this utility model is to provide a kind of fire resistant flame retardant tension shielding cable, to solve traditional cable fire poor-performing in prior art, shielding properties and tension are not good, easily cause cable short circuit and cisco unity malfunction when being subjected to the flame calcination, 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 fire resistant flame retardant tension shielding cable, include the array conductor, it is characterized in that: every group of conductor all is coated with composite fire layer and insulating barrier outward successively, and formation insulated wire cores, described composite fire layer is followed successively by mica tape from inside to outside, fire-resistant inorganic short fiber adhesive-layer and lapping layer, several insulated wire cores and the stranded rear formation cable core of reinforcement steel core, described cable core is coated with glass fiber tape, described glass fiber tape is coated with proof copper-wire braided screen and restrictive coating outward successively, be provided with packed layer and one deck steel disc between described cable core and glass fiber tape, the surface of steel disc scribbles underwater paint and insulating varnish.
Described a kind of fire resistant flame retardant tension shielding cable is characterized in that: described conductor is zinc-plated soft copper conductor.
Described a kind of fire resistant flame retardant tension shielding 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 fire resistant flame retardant tension shielding 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, for cable provides double-deck refractory protection, effectively promoted the fire resistance of cable, guarantee the use safety of cable when being subjected to high temperature sintering, extended the useful life of cable; Adopt the design stranded with strengthening steel core of several insulated wire cores, effectively promoted the resistance to tension of cable; Adopt proof copper-wire braided screen and steel disc design, effectively promoted shielding properties and the intensity of cable, guaranteed the result of use of cable under the complex work environment.
