Abstract
The utility model relates to a four in one fire-resistance optical cable of mineral insulating metal protective sleeve comprising an external protective sleeve and a cable core. The cable core includes a data copper cable[2], an optical cable[3], a radio-frequency cable[4], and a power cable[5] which are parallelly arranged. The utility model is characterized in that the external protective sleeve is a seamless metallic conduit[1] and a mineral fire-resistance layer is arranged between the cable core and the cavity wall of the seamless metallic conduit[1]. The mineral fire-resistance layer is lapped and coated by one or two of a mineral fibre mesh grid layer[6] and fire-resistance mica tape clad[7]. The mineral fibre mesh grid layer[6] is a mesh grid layer woven by taking the mineral fibre as longitude and latitude, while the fire-resistance mica tape clad[7] is a clad which is formed by the fire-resistance mica tape enwinding upward in a twist on the axial direction. The utility model has a good fire-resistance performance which can continually work normally in a fire environment without burning and can resist a heavy impact and extrusion caused by fire.
Description
Technical field
The utility model relates to a kind of mixed light cable, and it is the fire-resistant optical cable that data copper cable, optical cable, radio-frequency cable (being concentric cable) and power cable are combined as a whole, simultaneously transmitting optical signal, digital electric signal, analog electrical signal and electric energy.
Background technology
Along with the continuous development of information communication, users increase fast to the demand of information, such as the multimedia communication that utilizes computing machine, videophone and video conferencing etc.At present, the user realizes that broadband access is mainly still by data copper cable (i.e. five class copper cables (Cat.5), six class copper cables (Cat.6) etc.), but the limitation of its transmission capacity exposes, and therefore, jumbo Fiber to the home is only the inevitable choice of following broadband service.But at present the compatibility and the cost of the price of optical cable and the terminal device that matches thereof are still high, and making whole realizations Fiber to the home also needs one period time.Therefore, believe in a very long time, when buildings connects up, need optical cable and data copper cable cloth is all selected to use for people in the future.Simultaneously, the CATV (cable television) of popularizing on a large scale, radio communication base station, high-frequency signal transmission equipment, radar etc. are still analog and digital signal now, must adopt radio-frequency cable (concentric cable) during transmission, therefore, communications facility backbone and feeder line, user of access network line etc. still need use radio-frequency cable (being concentric cable).On the other hand, also have in some buildingss and will place electrical equipment, the power supply of its electrical equipment and the transmission of control signal need be used power cable.
Therefore in sum, present some heavy constructions (as intelligent building) need be laid data copper cable, optical cable, radio-frequency cable and power cable simultaneously when the finishing wiring.For adapting to this situation, four unification optical cables also once appearred on the market, comprise a plastics oversheath on the structure of this four unification mixed light cables, be equipped with data copper cable, optical cable, radio-frequency cable and power cable in the oversheath side by side.The oversheath that the outside of above-mentioned existing four unification optical cables has only one deck to make with flame retardant plastics (as tygon, Polyvinylchloride) or rubber, its continuous working temperature has only 60～105 ℃, not fire-resistant, can not be in fire hazard environment operate as normal continuously, and its cable intensity difference can not be resisted the weight bump and the extruding that cause because of fire, be unable to bear fire water and dash pouring, safety in utilization is not high.
Summary of the invention
Prior art is not fire-resistant in order to solve for the utility model, cable intensity difference, the not high problem of security, provides a kind of fire performance good, the fire-resistant optical cable of four unifications safe to use.
For achieving the above object, the technical solution adopted in the utility model is: the fire-resistant optical cable of a kind of mineral insulation protective metal shell four unifications, constitute by oversheath and cable core, comprise the data copper cable, optical cable, radio-frequency cable and the power cable that are set up in parallel in the described cable core, its innovative point is: described oversheath is a seamless metal pipe, the internal chamber wall of described cable core and seamless metal pipe is interval with the mineral flame retardant coating, and this mineral flame retardant coating is made of one of mineral fibres woven mesh layer and fire-resistant isinglass belt clad or both stacked coatings; Described mineral fibres woven mesh layer is with the mineral fibres woven mesh layer that braiding forms as warp and parallel, and the fire-resistant isinglass belt clad is with the fire-resistant isinglass belt clad that is entwined of spiral fashion in the axial direction.
Related content in the technique scheme is explained as follows:
1, in the such scheme, further preferred version is as follows: be filled with the mineral fibres filler in the inner chamber that described mineral flame retardant coating constitutes, and data copper cable, optical cable, radio-frequency cable, power cable are embedded in all in the mineral fibres filler.
2, in the such scheme, described " this mineral flame retardant coating is made of one of mineral fibres woven mesh layer and fire-resistant isinglass belt clad or both stacked coatings " comprises that following situation: a, mineral flame retardant coating only are made of the mineral fibres woven mesh layer; B, mineral flame retardant coating only are made of the fire-resistant isinglass belt clad; C, mineral flame retardant coating are total to double-layer structure by mineral fibres woven mesh layer and fire-resistant isinglass belt clad and constitute; D, mineral flame retardant coating are made of the sandwich construction that mineral fibres woven mesh layer and fire-resistant isinglass belt clad constitute.
And the ectonexine stacked package of mineral fibres woven mesh layer and fire-resistant isinglass belt clad is covered in proper order and is not limit, and can inside and outsidely replace.
3, in the such scheme, have annular or spiral embossing on the described seamless metal pipe, seamless metal pipe can be not damaged when making cable crooked with this, is convenient to bending, the convenient installation and construction.
The seamless metal pipe here plays fire-resistant and the outer protection effect, makes the cable refractory temperature reach the fusing point of metal, and, increased cable intensity, make it to resist the weight bump and the extruding that cause because of fire.
4, in the such scheme, described data copper cable, optical cable, radio-frequency cable and power cable can adopt existing all kinds of cables on the market.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
Because outside of the present utility model has seamless metal pipe to coat as oversheath, and in seamless metal pipe, be equipped with again by the fire-resistant isinglass belt layer or/and the mineral flame retardant coating that the mineral fibres woven mesh layer constitutes, reach the effect of mineral insulation protective metal shell, the fire performance of cable is improved greatly, the continuous working temperature can reach 200 ℃～250 ℃, fire-resistant maximum temperature reaches the fusing point of seamless metal pipe, and, this optical cable can be in fire hazard environment operate as normal continuously, do not burn, can resist the weight bump and the extruding that cause because of fire.
