Abstract
The utility model relates to the field of communication optical cables, in particular to a high temperature resistant optical cable with a good fireproof performance. At least one composite layer is arranged on each of the inner and outer surfaces of a sheath outside the optical cable, and each composite layer consists of a flame retardant layer and a reinforcement layer. As the composite layers with the fireproof function are added based on the original structure of the optical cable, and each composite layer consists of the flame retardant layer and the reinforcement layer, the composite layers ensures the organic combination of the physical and chemical properties of the structure and the materials, therefore, not only are the good fireproof and flame retardant effects obtained, but the mechanical intensity and the waterproof performance of the optical cable are improved relatively.
Description
Technical field
The utility model relates to the communications optical cable field, specifically refers to a kind of high temperature resistant optical cable of good fire protecting performance.
Background technology
The structure of existing optical cable is made up of optical fiber, core pipe, reinforcement unit and sheath mostly; Optical fiber places in the core pipe; Core pipe crust symmetria bilateralis is provided with the reinforcement unit of steel, and sheath is the cable skin that is wrapped in outside the core pipe, and common cable skin uses organic material more.The fire prevention of optical cable and anti-fire resistance are except that outside the Pass having with employed material, and the structure of existing optical cable also is a fire prevention and a relatively poor key factor of anti-anti-flammability.
The utility model content
The utility model purpose is to solve the deficiency of existing optical cable fire protecting performance, and a kind of high temperature resistant optical cable of simple in structure, dependable performance is provided.
A kind of high temperature resistant optical cable; Comprise optical fiber, core pipe, strengthen unit and sheath; Wherein the surfaces externally and internally of sheath is provided with one deck composite bed at least; Composite bed is made up of flame-retardant layer and enhancement Layer, the composite bed that is provided with between said jacket inner surface and the core pipe be included in the core pipe outward around the home one deck flame-retardant layer add one deck enhancement Layer around the home again; The outer composite bed of said sheath is at jacket outer surface flame-retardant layer and enhancement Layer around the home successively.
Said sheath is that the polyolefine material of low-smoke non-halogen flame-retardant is processed.
Said enhancement Layer is two-sided plastic-coated steel band, and the steel band outside surface also is provided with water blocking layer.
The both sides of the enhancement Layer outside surface of composite bed in said reinforcement unit is symmetrically placed in.
Also be provided with oversheath outside the enhancement Layer of external composite layer.
The beneficial effect of the high temperature resistant optical cable of the utility model: owing on the basis of former cable configuration, set up composite bed with fire-proof function; Composite bed is made up of flame-retardant layer and enhancement Layer; Said composite bed has been realized the combination of structure and material physicochemical property; Not only obtained good fire prevention and flame retardant effect, and relative raising the physical strength and the water resistance of optical cable.The utility model is rational in infrastructure succinct, has certain range of application and market outlook.

Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Be to be understood that practical implementation instance described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Among the embodiment of ginseng Fig. 1; Optical fiber 1 is placed through among the core pipe 2; The composite bed of forming by the enhancement Layer 32 of flame-retardant layer of loose mixed type mica tape 31 and two-sided plastic-coated steel band around the home between core pipe 2 and the sheath 53; Wherein, the outside surface of the enhancement Layer 32 of two-sided plastic-coated steel band is coated with water-proofing powder, has the water blocking layer 321 of water resistance with formation; The monosymmetric of said steel band 32 outside surfaces is provided with 2 parallel steel wires as strengthening unit 4, has the physical strength that enough tensions, lateral pressure resistant and antifatigue are destroyed to guarantee optical cable; By low-smoke non-halogen flame-retardant PE sheath 5 above-mentioned optical fiber 1, core pipe 2, composite bed 3 and 2 are from inside to outside strengthened unit 4 and wrap up in and be placed in one, constitute first kind of embodiment of the utility model.Low-smoke non-halogen flame-retardant PE sheath not only can effectively stop spreading of the intensity of a fire, and can not produce harmful gas.
Fig. 2 is the embodiment of external composite layer in a kind of being provided with; This embodiment promptly is that the outside surface at the sheath 5 of above-mentioned first kind of embodiment is provided with the composite bed 6 outside one deck again; Outer composite bed 6 comprises wide mixed type mica tape 61, two-sided plastic-coated band 62 and oversheath 7; Wide mixed type mica tape 61 is wound on the outside surface of sheath 5; Two-sided plastic-coated band 62 is wound on the outside surface of wide mixed type mica tape 61 again, and then optical fiber 1, core pipe 2, interior composite bed 3, reinforcement unit 4, sheath 5 and outer composite bed 6 are placed through among the oversheath 7 jointly, promptly constitute second kind of embodiment of this practical firewood type.This embodiment causes optical cable that bigger improvement and raising are all being arranged aspect fire protecting performance, water resistance and the physical strength because the composite bed 3 and outer composite bed 6 and oversheath 7 in being provided with implemented double shielding than first kind of embodiment to optical cable.The utlity model has application surface more widely, be particularly suited for fire prevention, the demanding area of classification of waterproof, position are laid.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
