Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of environmental protection flame retardant telecommunication cable.
The utility model is taked following technical scheme to realize: a kind of environmental protection flame retardant telecommunication cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier and oversheath, and described cable body inside is provided with many conductors; One deck protective sleeve is set outside described conductor; One deck insulating barrier is set outside described protective sleeve; Described insulating barrier, protective sleeve and conductor form cable core jointly; Described cable core cross section is circular configuration; Described cable body inside is provided with many cable cores; Described cable core be outside equipped with multiple drain wire and cable core tangent; One deck high-temperature-resistant layer is set outside described cable core; Described high-temperature-resistant layer, between drain wire and cable core, gap portion is provided with packed layer; Described high-temperature-resistant layer extrudes one deck foil shielding layer; Described foil shielding layer closely extrudes one deck oversheath outward.
Above-mentioned a kind of environmental protection flame retardant telecommunication cable, described conductor is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire.
Above-mentioned a kind of environmental protection flame retardant telecommunication cable, described high-temperature-resistant layer is made up of the rubber combined carrying material of ceramic silicon.
Above-mentioned a kind of environmental protection flame retardant telecommunication cable, described insulating barrier is woven by tin annealed copper wire to form, and the tin annealed copper wire count of described insulating barrier is no less than 80%.

Above-mentioned a kind of environmental protection flame retardant telecommunication cable, described oversheath adopts semiconductive plastics to extrude formation.
The utility model has following beneficial effect in sum: the utility model has reasonable in design, good communication quality and the advantage such as high temperature resistant, described foil shielding layer effectively can strengthen the ability that outside electromagnetic interference kept out by cable, simultaneously again can the electromagenetic wave radiation of control cables itself, the normal work of around other equipment and network can not be disturbed, thus be adapted to more occasion.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, cable body; 2, conductor; 3, protective sleeve; 4, insulating barrier; 5, packed layer; 6, drain wire; 7, high-temperature-resistant layer; 8, foil shielding layer; 9, oversheath.
Embodiment
As shown in Figure 1, a kind of environmental protection flame retardant telecommunication cable, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 4 and oversheath 9, and described cable body 1 inside is provided with many conductors 2; Outside described conductor 2, one deck protective sleeve 3 is set; Outside described protective sleeve 3, one deck insulating barrier 4 is set; Described insulating barrier 4, protective sleeve 3 and conductor 2 form cable core jointly; Described cable core cross section is circular configuration; Described cable body 1 inside is provided with many cable cores; It is tangent with cable core that described cable core is outside equipped with multiple drain wire 6; One deck high-temperature-resistant layer 7 is set outside described cable core; Described high-temperature-resistant layer 7, between drain wire 6 and cable core, gap portion is provided with packed layer 5; Described high-temperature-resistant layer 7 extrudes one deck foil shielding layer 8; Described foil shielding layer 8 is outer closely extrudes one deck oversheath 9.
Described conductor 2 is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor 2 structure is easy to processing, making length is unrestricted, there is during use certain flexibility and bendability, facilitate the laying of workpeople; The outer protective sleeve 3 arranged of described conductor 2 is fiberglass pipe, effectively can improve the bending property of cable body 1, easy to use and can meet the requirement of cable to electromagnetic field; Described insulating barrier 4 is woven by tin annealed copper wire to form, and can improve the insulation property of cable body 1, effectively make cable working stability; Described packed layer 5 makes cable body 1 internal structure compacter, prevent its because of the external world stressed excessive and damage; Described drain wire 6 can reach protective ground and bonding requirement, effectively can solve the problem of cross-talk between line pair, ensures effective transmission of signal; Described high-temperature-resistant layer 7 is made up of the rubber combined carrying material of ceramic silicon, thus substantially increase the resistance to elevated temperatures of cable body 1, can not occur situation about melting again under hot environment, cable also can normally be used in high temperature environments; Described foil shielding layer 8 effectively can strengthen the ability that outside electromagnetic interference kept out by cable, simultaneously again can the electromagenetic wave radiation of control cables itself, can not disturb the normal work of other equipment of surrounding and network, thus be adapted to more occasion; Described oversheath 9 adopts semiconductive plastics to extrude formation, can bear higher temperature, and can not produce harmful Substances Pollution environment in hot environment, thus make its environmental-protecting performance more excellent, meet present the advocated environmental protection concept of people.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
