The utility model relates to optical communication, power transmission technology field, relates in particular to a kind of built on stilts beaming type Optical Fiber Composite low-voltage insulation cable.
Background technology
Built on stilts beaming type insulated cable can be widely used in the low-voltage power distribution system, and this product has characteristics such as weatherability is good, line loss is little, the easy construction duration is short, can effectively prevent stealing, leaky and have the security performance of transmitting electricity preferably.
Along with country carries forward vigorously " integration of three networks "; Accelerating " electric power-optical fiber " registers one's residence; Built on stilts beaming type insulated cable can not satisfy the intelligent grid Development Trend, and the end that can not solve information superhighway simultaneously inserts problem, for the user provides convenient more and modern life style.
" electric power-optical fiber " can be realized the Joint construction and sharing of network infrastructure to the family, significantly reduce " integration of three networks " implementation cost, improves the comprehensive efficiency of operation of network, aspect energy-conserving and environment-protective, remarkable advantages is arranged." electric power-optical fiber " only needing to have realized once construction, the problem that passage, disposable solution optoelectronic composite cable are registered one's residence technically to the family; Instead is the repeatedly construction of many circuits such as electric wire, netting twine, telephone wire, cable TV in the past, practices thrift cable resource and public safety greatly.
The Chinese patent of CN201020512395.0 discloses a kind of parallel beaming type Optical Fiber Composite low pressure aerial insulated cable; This utility model discloses a kind of parallel beaming type Optical Fiber Composite low pressure aerial insulated cable; Comprise at least two heart yearns that laterally arrange and the dowel that connects adjacent two heart yearns; Also comprise one parallel with heart yearn and through dowel and optical fiber that heart yearn is connected wherein; The cable of this utility model has only an optical fiber, and this optical fiber only is connected with outermost heart yearn, defines the quantity and the connected mode of optical fiber like this.
The utility model content
For solving " electric power-optical fiber " to the family; Only needing to realize once construction, the problem that passage, disposable solution optoelectronic composite cable are registered one's residence; The utility model provides a kind of built on stilts beaming type Optical Fiber Composite low-voltage insulation cable; Dual-use function with electric power transfer and optical communication, simultaneously simple in structure.
The utility model is realized through following technical scheme: a kind of built on stilts beaming type Optical Fiber Composite low-voltage insulation cable; Comprise heart yearn that is parallel to each other and the band muscle that is connected heart yearn; Described cable also comprises optical fiber; Optical fiber connects with heart yearn through the band muscle and is parallel with heart yearn, and perhaps optical fiber directly connects with heart yearn and is parallel with heart yearn, at least one of the quantity of said optical fiber.
The both sides of optical fiber are connected with the band muscle and are connected with heart yearn through the band muscle, also can be that a side of optical fiber is connected with the band muscle and is connected with heart yearn through the band muscle.When a side of optical fiber was connected with the band muscle, optical fiber can be located at the inboard of band muscle or show side or interior table both sides.Optical fiber can connect in different at different position and different with the band muscle that is connected heart yearn.
Heart yearn is made up of the insulating barrier of plain conductor and coated metal lead; Plain conductor is by forming common conductive copper wire core or stranded pressing of aluminium conductor wire core, and insulating barrier generally can be selected polyethylene insulation material, weather resistant polychloroethylene insulation material or crosslinked polyethylene insulation material for use.The light unit protects optical fiber pine pipe box by optical fiber and bag and insulating protective layer is formed.Insulating protective layer adopts identical insulating material with the band muscle that links to each other with insulating barrier, becomes one structure so that make an extrusion modling.Because heart yearn itself has the intensity of four-core one, adds that optical fiber need not external supplemental support line.Built on stilts like this beaming type Optical Fiber Composite low-voltage insulation cable has the dual-use function of electric power transfer and optical communication, solves the problem of the end access of information superhighway simultaneously.
According to the different occasions demand, the quantity of core can be one, two, three, four or more, and the quantity of optical fiber also can be one or more.When several numbers of core are 1, can form phase line power supply, optical fiber is connected through the band muscle with heart yearn, and connecting portion can be any.Several numbers of core can be formed a phase line one zero line and be used for power supply when being 2, and two heart yearns are connected through the band muscle, and optical fiber is connected with heart yearn through the band muscle and also can directly be connected with fresh, and connecting portion can be selected the then outer of middle or two heart yearns of two heart yearns.When several numbers of core are 3; Can form triple line and be used for power supply, three heart yearns are connected through the band muscle, and optical fiber is connected with heart yearn or directly links to each other with heart yearn through the band muscle; Connecting portion can be selected the then outer of heart yearn centre or heart yearn, and heart yearn can link to each other with multifiber like this.When several numbers of core are 4; Can form triple line one zero line and be used for power supply; Can arrive the family by three-phase and four-line, quad is connected through the band muscle, and optical fiber is connected with heart yearn through the band muscle or directly is connected with heart yearn; Connecting portion can select in the middle of the heart yearn or outward then, heart yearn can link to each other with multifiber like this.
As preferably, when the heart yearn more than 2 was connected with optical fiber, the optimal site of optical fiber was selected in the middle of the heart yearn; Though insulating protective layer is arranged during optical fiber fabrication, because optical fiber has fragility, product is avoided dragging along the ground when construction; Optical fiber designs is in the centre, and the external diameter of optical fiber own has protectiveness less than the heart yearn external diameter in construction period; And the light unit is made up of optical fiber and loose pipe box and belongs to nonmetal central tube, can avoid interference.
Compared with prior art, the beneficial effect of the utility model is:
(1) energising and communication function are integrated, and one-time-reach-place is installed, and avoid the secondary wiring, can effectively reduce expenses such as construction, networking, satisfy the demand of the modern life, have also satisfied the demand of national grid power optical fiber pilot project simultaneously.
(2) simple in structure, low cost of manufacture, reliable installation.
