Abstract
The utility model discloses a fireproof, flame-retardant, termite-prevention and tensile cable. The cable comprises a plurality of conductors, and a composite fireproof layer and an insulating layer are successively wrapped outside each conductor, so that insulating cores are formed. Each composite fireproof layer successively includes, from inside the 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, and a glass fiber tape is wrapped outside the cable core. An inner sheath layer, a nylon protective layer and an outer sheath layer are successively wrapped outside the glass fiber tape. A filling layer is disposed between the cable core and the glass fiber tape. Through a design of the composite fireproof layers and the glass fiber tape, the cable of the utility model is protected by two fireproof layers, is effectively enhanced in terms of fireproof performance, is guaranteed to be safe to use when being burnt at a high temperature, is effectively prevented from being bitten by termites, is improved in terms of tensile performance and is prolonged in terms of the service life.
Description
Technical field
The utility model relates to the electric wire field, is specially the termite-proof tension cable of a kind of 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 flame resistant not of thermal insulation difference.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 because of short circuit; the resistance to tension deficiency is subjected to stretch effects also can shorten the useful life of cable for a long time.
The utility model content
The purpose of this utility model provides the termite-proof tension cable of a kind of fire resistant flame retardant, not good to solve cable fire resistance traditional in the prior art, cause cable short circuit easily and cisco unity malfunction when being subjected to the flame calcination, bitten by termite easily, the resistance to tension deficiency is subjected to stretch effects can shorten the cable problem in useful life for a long time.
For achieving the above object, the technical solution adopted in the utility model is:
The termite-proof tension cable of a kind of 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 inner sheath, nylon overcoat and oversheath outward successively, is provided with packed layer between described cable core and the glass fiber tape.
The termite-proof tension cable of described a kind of fire resistant flame retardant is characterized in that: described conductor is zinc-plated soft copper conductor.
The termite-proof tension cable of described a kind of 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 tension cable of described a kind of fire resistant flame retardant is characterized in that: described oversheath adopts silicon rubber 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 the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of termite; Adopt several insulated wire cores and strengthen the stranded design of steel core, promoted the resistance to tension of cable effectively, prolonged the useful life of cable.
