Abstract
The utility model discloses a fire-resistant flame retardant flexible cable, comprising a plurality of groups of conductors, wherein each group of conductor is sequentially coated with a composite fire-resistant layer and an insulating layer, thereby forming an insulating wire core; the composite fire-resistant layer comprises a mica tape, a fire-resistant inorganic short-staple adhesive layer and a wrapping layer successively from inside to outside; and each insulating wire core is coated with a slip layer, a cable core is formed by twisting a plurality of the insulating wire cores, a glass fiber tape is coated outside the cable core, a sheath layer is coated outside the glass fiber tape, and a filling layer is arranged between the cable core and the glass fiber tape. The fire-resistant flame retardant flexible cable has simple structure and good fire resistant and flame retardant performances, the sliding property among the insulating wire cores is good, the cable is convenient to bent and uneasily deformed, the service life of the cable is prolonged, and the application safety of the cable is ensured.
Description
Technical field
The utility model relates to the electric wire field, is specially a kind of fire resistant flame retardant flexible 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 flame resistant not.Therefore; when breaking out of fire; the not flame resistant baking of this class cable; be difficult to isolated flame, so flame is easy to these protective layers of ablation, makes cable directly be subject to the calcination of flame; cause cable can not work because of short circuit; and common cable is difficult for bending, affected easily by bending and deforms, and causes shorten the useful life of cable.
The utility model content
The purpose of this utility model is to provide a kind of fire resistant flame retardant flexible cable, be difficult for bending to solve cable traditional in prior art, fire resistance is not good, is easily bent the problem that causes cable shortening in useful life with the flame calcination and be short-circuited that affects during use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fire resistant flame retardant flexible cable, 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, every eradication edge core is coated with glide lamella, the stranded formation cable core of several insulated wire cores, described cable core is coated with glass fiber tape, described glass fiber tape is coated with restrictive coating, is provided with packed layer between described cable core and glass fiber tape.
Described a kind of fire resistant flame retardant flexible 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 flexible cable is characterized in that: described glide lamella is the macromolecule material film layer of low-friction coefficient.
Described a kind of fire resistant flame retardant flexible 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, adopts the design of composite fire layer and glass fiber tape, for cable provides double-deck refractory protection, has effectively promoted the fire resistance of cable, has guaranteed the use safety of cable when being subjected to high temperature sintering; Employing makes to have good slipping property between each insulated wire cores in the design of insulated wire cores outer cladding glide lamella, and convenience bends, and not yielding, has extended the useful life of cable.
