Abstract
The utility model discloses a fireproof flame retardation tensile double shielding cable comprising plurality groups of conductors, each group conductor is wrapped by a composite fireproof layer, an insulation layer and a copper wire braid sub shielding layer in sequence to form an insulation core, the composite fireproof layer comprises in sequence a mica tape, a fireproof inorganic short fiber viscose glue layer and a taped covering from inside out, the insulation cores and reinforced steel cores are twisted to form a cable core, the cable core is wrapped by a glass fiber tape, the glass fiber tape is wrapped by a copper belt total shielding layer and a sheath layer in sequence, and a filling layer is arranged between the cable core and the glass fiber tape. The fireproof flame retardation tensile double shielding cable is simple in structure, has very good fireproof property, shielding performance and tensile capacity, usage safety of the cable under high temperature firing is guaranteed, service life of the cable is prolonged, and usage effect of the cable under complex work environment is guaranteed.
Description
Technical field
The utility model relates to the electric wire field, is specially a kind of fire resistant flame retardant tension 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 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 these protective layers that are easy to ablate, make 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 are not good, 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 fire resistant flame retardant tension screened cable, to solve traditional cable fire poor-performing in the 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 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 proof copper-wire braided 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, 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 the total screen of copper strips and restrictive coating outward successively, is provided with packed layer between described cable core and the glass fiber tape.
Described a kind of fire resistant flame retardant tension screened cable is characterized in that: described conductor is zinc-plated soft copper conductor.
Described a kind of fire resistant flame retardant tension 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 fire resistant flame retardant tension 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, 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, prolonged 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 the double layer screen design of proof copper-wire braided sub-shield and the total screen of copper strips, effectively promoted the shielding properties of cable, guaranteed the result of use of cable under the complex work environment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of fire resistant flame retardant tension screened cable, include array conductor 1, every group of conductor 1 outer composite fire layer, insulating barrier 5 and proof copper-wire braided sub-shield 7 of all being coated with successively, and formation insulated wire cores, the composite fire layer is followed successively by mica tape 2, fire-resistant inorganic short fiber adhesive-layer 3 and lapping layer 4 from inside to outside, several insulated wire cores and reinforcement steel core 6 stranded rear formation cable cores, cable core is coated with glass fiber tape 8, be coated with successively the total screen 9 of copper strips and restrictive coating 10 outside the glass fiber tape 8, be provided with packed layer 11 between cable core and the glass fiber tape 8.
