Technical field
The invention belongs to electric power and technical field of cables, especially relate to a kind of electric power to family optical cable.
Background technology
Along with electric power, the developing rapidly of telecommunications, the quantity of information that electrical network carries increases day by day, for this reason, it may be necessary to the higher optical fiber of communication capacity carrys out the transmission of signal in power-assisted electric utility;As the carrier of signal transmission, optoelectronic composite cable application in electrical network is increasing, but, although the existing optoelectrical cable that can be used for power domain has more specification and model at present, but the requirement laid and use can not be met.
Notification number is: CN201084492, name are called: the patent of optical fiber power cable, includes power wire core, ground connection core and optical cable, described power wire core, ground connection core and optical cable wrapped up by oversheath after in flat.This patent cable allows operating temperature to be 90 DEG C for a long time, and minimum permission operating temperature is-35 DEG C;Possess the weather resisteant of excellence, wearability, there is oil resistant characteristic.Special flat type structural design can use in high mechanical stress, high alternating bending frequency occasion;Utilize fiber-optic transfer, solve electric induction problem.Owing to it is squashed structure, therefore, it is not easy to laying in pipeline.
Notification number is: CN202584869U, name are called: a kind of optical-power composite cable of the patent disclosure of a kind of optical-power composite cable, including optic fibre core and electric power cable core, optic fibre core includes four optical fiber cable cores and is evenly distributed on four regions of cross supporting frame, is enclosed with Loose tube, waterproof layer outside optic fibre core successively;Electric power cable core includes the conductor that three cross sections are sector of parcel insulating barrier, flame retardant coating, screen layer it is enclosed with respectively outside three conductors including insulating barrier, inner restrictive coating is constituted by extrusion moulding outside optic fibre core and electric power cable core, inner restrictive coating is externally provided with armor, and the outer extrusion moulding of armor has the external sheath layer of dumb-bell shape.This reasonable in design, optical cable and power cable are combined into one, it is achieved that optical signal and the signal of telecommunication transmit simultaneously, additionally, have good water resistance, fire resistance, structural compactness, extend service life.But, due to the dumbbell shape that it is special, therefore, also it is not easy to pipeline laying, additionally, due to the junction of dumb-bell shape is relatively thin, and cable unit and fiber unit weight great disparity are relatively big, and therefore, aging through the long period, very easily ruptures, ftractures in junction;Thus affecting the performance of cable.
Notification number is: CN102314968A, name are called: a kind of power optical fiber to the patent of family cable, including the first insulated conductor, the second insulated conductor, butterfly optical cable, envelopes the first outer jacket of the first insulated conductor, envelopes the second outer jacket of the second insulated conductor, envelope the 3rd outer jacket of butterfly optical cable and be positioned at cavity that is within the 3rd outer jacket and that can hold described butterfly optical cable;First insulated conductor, the second insulated conductor lay respectively at the both sides of butterfly optical cable;First outer jacket, the second outer jacket, the 3rd outer jacket are one-body molded;Arbitrary with in the plane of the first conductor axis perpendicular, the outer rim of the 3rd outer jacket is protruded to cavity.The invention solves the problems such as cable of the prior art not easily lays, easily openable, density of optic fibre be not little;The present invention have stable performance of being heated, easily spread split, modularity, easily produce, easily lay, the easy beneficial effect such as construction.Although reached simple structure and optical cable unit is easily separated, more easy heat radiation equivalence fruit, but, be figure-8 structure equally due to it, therefore, be also not easy to pipeline laying.And, this cable there is no standby electricity unit, it does not have ground wire, therefore, during use, safety is poor;Additionally, butterfly cable therein is rectangular shape, therefore, relative cost is higher, very uneconomical.
