Abstract
The utility model discloses a waterproof termite-proof fireproof tensile flexible cable. The cable comprises multiple conductors, and each conductor is successively wrapped in a composite insulation layer and a mica tape to form an insulating conductor core, wherein the composite insulation layer successively includes a semi-conductive nylon tape, a polyvinyl chloride insulation layer and a semi-conductive shielding layer from internal to external, and each insulating conductor core is wrapped in a slip layer; the multiple insulating conductor cores are intertwisted with reinforced steel cores to form a cable core; the cable core is wrapped in a radial waterproof buffer layer; the radial waterproof buffer layer is successively wrapped in a non-woven fabric belting layer, a nylon protective layer and a sheath layer; and a filling layer is arranged between the cable core and the radial waterproof buffer layer. The waterproof termite-proof fireproof tensile flexible cable has better insulating properties, fireproof performance, waterproof performance and tension resistance; the cable is effectively prevented from being biting by the termite; use safety of the cable is ensured; and good slip performance exists between the insulating conductor cores, so that the cable is convenient to bend and not easy to deform, thereby effectively prolonging service life of the cable.
Description
Technical field
The utility model relates to the electric wire field, is specially the termite-proof fire-resistant tension flexible cable of a kind of waterproof.
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, in use, will avoid not only that cable is mechanically damaged, insulation harm, ageing of insulation are rotten etc., also will avoid insulation to make moist.Cable need sometimes to be laid in ground or the place of water is arranged, because the permeability of cable sheath material, perhaps cable cover(ing) is by mechanical damage, water has entered cable inside, causes insulating barrier to form water tree, the continuous oxidation of water tree, cause destruction to insulation, shortened the life-span of cable so greatly, and common cable bites by termite easily, insulation property, fire resistance are not good, the resistance to tension deficiency, difficult bending is stretched and bending influences easy deformation, causes shorten the useful life of cable.
The utility model content
The purpose of this utility model provides the termite-proof fire-resistant tension flexible cable of a kind of waterproof, not good to solve insulating performance of cable, fire resistance traditional in the prior art, there is potential safety hazard, and bitten by termite easily, the resistance to tension deficiency, be difficult for bending, water resistance is not good, the problem that is stretched easily, bends after long-time the use and seep water and influence and cause cable to shorten useful life.
For achieving the above object, the technical solution adopted in the utility model is:
The termite-proof fire-resistant tension flexible cable of a kind of waterproof, include the array conductor, it is characterized in that: every group of conductor all is coated with composite insulation layer and mica tape outward successively, and formation insulated wire cores, described composite insulation layer is followed successively by wrapped semiconductive nylon tape from inside to outside, polyvinyl chloride insulation layer and semiconductive shielding layer, every eradication edge core is coated with glide lamella, several insulated wire cores constitute cable core with the stranded back of reinforcement steel core, described cable core is coated with radially water-blocking buffer layer, described radially water-blocking buffer layer is coated with the nonwoven fabrics twining package tape outward successively, nylon overcoat and restrictive coating, described cable core and radially be provided with packed layer between the water-blocking buffer layer.
The termite-proof fire-resistant tension flexible cable of described a kind of waterproof is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.
The termite-proof fire-resistant tension flexible cable of described a kind of waterproof is characterized in that: described restrictive coating adopts flame-proof polyvinyl chloride to make.
The termite-proof fire-resistant tension flexible cable of described a kind of waterproof is characterized in that: described packed layer is the intumescent inserts that blocks water.
The beneficial effects of the utility model are:
The utility model is simple in structure, adopts the design of composite insulation layer and mica tape, has promoted the insulation property and the fire-resistance property of power cable effectively, can stand the thermal-flame calcination for a long time, has ensured the safe in utilization of power cable; Employing coats the design of glide lamella outside insulated wire cores, make to have good slipping property between each insulated wire cores, convenient bending, and not yielding; 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 radially design of water-blocking buffer layer, after water entered oversheath, the material water-proof material water-swellable stoped moisture further to spread along cable, has the excellent waterproof effect, has prolonged the useful life of cable effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the termite-proof fire-resistant tension flexible cable of a kind of waterproof, include array conductor 1, every group of conductor 1 outer composite insulation layer and mica tape 5 of all being coated with successively, and formation insulated wire cores, composite insulation layer is followed successively by wrapped semiconductive nylon tape 2 from inside to outside, polyvinyl chloride insulation layer 3 and semiconductive shielding layer 4, every eradication edge core is coated with glide lamella 6, several insulated wire cores constitute cable cores with reinforcement steel core 7 stranded backs, cable core is coated with radially water-blocking buffer layer 8, radially be coated with nonwoven fabrics twining package tapes 9 successively outside the water-blocking buffer layer 8, nylon overcoat 10 and restrictive coating 11, cable core and radially be provided with packed layer 12 between the water-blocking buffer layer 8.
Glide lamella 6 is the macromolecule material film layer of low-friction coefficient, and restrictive coating 11 adopts flame-proof polyvinyl chlorides to make, and packed layer 12 is the intumescent inserts that blocks water.
