Abstract
The utility model discloses a tensile, environment-friendly, fireproof, flame-retardant and termite-resistant cable. The cable comprises a plurality of conductors, and a composite fireproof layer and a crosslinked polyethylene insulating layer are successively wrapped outside each conductor, so that insulting cores are formed. Each composite fireproof layer successively comprises, from inside to outside, a mica tape, a fireproof inorganic short fiber viscose glue layer and a taped layer. The insulating cores and reinforced steel cores are intertwisted to form a cable core. A glass fiber tape is wrapped outside the cable core. A halogen-free taped belt, a nylon protective layer and a low-smoke and halogen-free polyolefin sheath layer are successively wrapped outside the glass fiber tape. A filling layer is arranged between the cable core and the glass fiber tape. The cable of the utility model exhibits excellent fireproof and tensile properties, is effectively prevented from being bitten by termites, is guaranteed to be safe to use when being burnt under a high temperature, is prolonged in terms of the service life, is not liable to release a lot of heavy smoke and poisonous and harmful gas during combustion, causes less environment pollution and is convenient for work of rescue.
Description
Technical field
The utility model relates to the electric wire field, is specially the fire-resistant fire-retardant termite-proof cable of a kind of tension environment-friendly type.
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; therefore flame these protective layers that are easy to ablate; make cable directly be subjected to the calcination of flame, cause cable can not work, and common cable is bitten easily by termite because of short circuit; resistance to tension is not good; useful life is shorter, can discharge a large amount of dense smokes and toxic and harmful during burning, influences rescue work and atmospheric environment.
The utility model content
The purpose of this utility model provides the fire-resistant fire-retardant termite-proof cable of a kind of tension environment-friendly type, not good to solve cable fire resistance and resistance to tension traditional in the prior art, bitten by termite easily, useful life is shorter, easy short circuit when breaking out of fire is subjected to the flame calcination, and can discharge a large amount of dense smokes and toxic and harmful, influence the problem of rescue work and atmospheric environment.
For achieving the above object, the technical solution adopted in the utility model is:
The fire-resistant fire-retardant termite-proof cable of a kind of tension environment-friendly type, include the array conductor, it is characterized in that: every group of conductor all is coated with composite fire layer and crosslinked polyetylene insulated layer 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 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 the Halogen twining package tape outward successively, nylon overcoat and low-smoke halogen-free polyolefin restrictive coating are provided with packed layer between described cable core and the glass fiber tape.
The fire-resistant fire-retardant termite-proof cable of described a kind of tension environment-friendly type is characterized in that: described conductor is zinc-plated soft copper conductor.
The fire-resistant fire-retardant termite-proof cable of described a kind of tension environment-friendly type is characterized in that: described fire-resistant inorganic short fiber adhesive-layer adopts polycrystal alumina or polycrystalline mullite short fiber to make.
The beneficial effects of the utility model are:
The utility model is simple in structure, adopts the design of composite fire layer and glass fiber tape, for cable provides double-deck refractory protection, promoted the fire resistance of cable effectively, has guaranteed cable safe in utilization when being subjected to high temperature sintering; Adopt several insulated wire cores and strengthen the stranded design of steel core, promoted the resistance to tension of cable effectively, prolonged useful life; Adopt the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of termite; Adopt the design of Halogen twining package tape and low-smoke halogen-free polyolefin restrictive coating, make cable can not discharge a large amount of dense smokes and toxic and harmful when burning takes place, environmental pollution is less, has made things convenient for the carrying out of rescue work.
