Abstract
The utility model disclose a tension-resistant fireproof flame-retardant anti-termite shielding cable. The cable comprises multiple conductors, wherein each conductor is wrapped in a composite fireproof layer and an insulating layer to form an insulating core, and the composite fireproof layer includes a mica tape, a fireproof inorganic short fiber viscose layer and a taped covering from inside to outside; the multiple insulating cores are stranded with strengthening steel cores to form a cable core; the cable core is wrapped in a glass fiber tape; the glass fiber tape is successively wrapped in a copper wire braided shielding layer, a nylon protective layer and a sheath layer; and the a filling layer is arranged between the cable core and the glass fiber tape. The tension-resistant fireproof flame-retardant anti-termite shielding cable is simple in structure, and has better fireproof performance, shielding performance and mechanical strength, so that it is effectively prevented the cable from being bitten by the termite, use safety of the cable during high-temperature calcinations is ensured, and service life of the cable is prolonged.
Description
Technical field
The utility model relates to the electric wire field, is specially the termite-proof shielded type cable of a kind of tensile type fire resistant flame retardant.
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 termite easily and has potential safety hazard because of short circuit; shielding properties and tensile property are 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 the termite-proof shielded type cable of a kind of tensile type fire resistant flame retardant, relatively poor to solve cable fire resistance traditional in the prior art, shielding properties and tension are not good, bitten by termite easily, cause cable short circuit easily 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:
The termite-proof shielded type cable of a kind of tensile type fire resistant flame retardant, 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, fire-resistant inorganic short fiber adhesive-layer and lapping layer from inside to outside, several insulated wire cores constitute cable core with the stranded back of reinforcement steel core, described cable core is coated with glass fiber tape, described glass fiber tape is coated with copper wire woven shield, nylon overcoat and restrictive coating outward successively, is provided with packed layer between described cable core and the glass fiber tape.
The termite-proof shielded type cable of described a kind of tensile type fire resistant flame retardant is characterized in that: described conductor is zinc-plated soft copper conductor.
The termite-proof shielded type cable of described a kind of tensile type fire resistant flame retardant is characterized in that: described fire-resistant inorganic short fiber adhesive-layer adopts polycrystal alumina or polycrystalline mullite short fiber to make.
The termite-proof shielded type cable of described a kind of tensile type fire resistant flame retardant 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 several insulated wire cores and strengthen the stranded design of steel core, promoted the resistance to tension of cable effectively; Adopt the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of termite; Adopt the design of copper wire woven shield, promoted the shielding properties of cable effectively, guaranteed the result of use of cable under the complex work environment.
