Description
Technical field
The utility model and a kind of armour photoelectric comprehensive power cable.
Background technology
In the cable of prior art, a cable only possesses a kind of purposes, if will realize optical transmission communication and supply of electric power, will lay two kinds of cables at least, and promptly a kind of optical cable and a kind of power cable are realized.Above-mentioned this present situation not only need take the bigger space of laying, and also makes manufacturing cost and the expense of laying roll up simultaneously.
The utility model content
The purpose of the utility model provides a kind of photoelectricity cable core of optical cable and power cable variety classes purposes that utilizes to combine to existing weak point in the above-mentioned prior art just; Promptly the optical cable that is used for the transmission medium guided wave be used to transmit and distribute the power cable of electric energy to pass through structural design; Make each other to be independent of each other, concentrate on the couplet armour photoelectric comprehensive power cable of realizing multi-functional transmission in the cable.The cable of the utility model can reduce the radical that lays of traditional special purpose cable, reduces its manufacturing cost and lays expense.
The purpose of the utility model can realize through following technique measures:
The couplet armour photoelectric comprehensive power cable of the utility model comprises the light unit cable core that adopts fiber optic materials to be prepared from, around some electric power cable cores of light unit cable core setting and be wrapped in the outer belting layer of electric power cable core, lining material layer, lock armo layer successively; Said smooth unit cable core is by some optical fiber and is wrapped in the outer cover of optical fiber successively and moulds layer (cover is moulded the pipe layer), aramid fiber layer that light unit restrictive coating is formed.
Fiber count described in the utility model is: 2 ~ 48 cores; Said lock armo layer is to buckle the helix tube that forms by metal tape (galvanized steel strip, stainless steel band, aluminum alloy strip etc.) edge to constitute.
Electric-cable core described in the utility model is the insulated wire cores of conventional structure, is looped around around the light unit cable core according to 20 ~ 40 times pitch of the outer warp of cable core.
It is the center that the utility model adopts light unit cable core, is around the electric power cable core around it, through reasonable structural design, guarantees the transmission characteristic and the mechanical performance of optical fiber.
Because the transmission characteristic of optical fiber directly influences the repeater span and the transmission capacity of fiber optic cable communications, its mechanical performance directly determines the useful life of optical fiber.Added the very high aramid yarn of modulus of elasticity so mould the mode of twining with parcel outside the layer, guaranteed that light unit cable core in power cable, can not sustain damage, produced loss, avoided influencing each other at the cover of its light unit cable core.
In addition.Because the comprehensive cable of the utility model adopts the lock armo structure, overcome many defectives that traditional double band gap armouring exists, like traditional double band gap armouring oversheath must be arranged, alice damage sheath might appear in cable biobelt when bending.Because oversheath is arranged, adding biobelt is the wrapped structure in gap, and the bending property of cable is not good enough relatively.The utility model adopts lock armo, does not need oversheath, and metal tape is the volution cannula-like, can effectively protect comprehensive cable not receive extraneous mechanical damage, can bear radial pressure.Cable can not produce to slip when crooked and take off or the alice phenomenon, guarantees the good bending property of cable.
The beneficial effect of the utility model is following:
Because the utility model has been considered the utilance of comprehensive cable structure space,, effectively reduce light, cables manufacturing cost and lay expense for fiber optic cable communications and electric power transfer offer convenience.Join armour photoelectric comprehensive power cable with one and can replace the single optical cable of conventional func, power cable, save and lay the space.Adopt and join the armour structure; Form a safe and reliable volution sleeve pipe, do not need oversheath, reduce and manufacture operation; Practice thrift cost; Make comprehensive cable outstanding representation all arranged aspect the operating characteristics such as pressure, bending, and directly crane span structure lay, and lays for installation to offer convenience rust resistance, fail safe, anti-pounding.
Description of drawings
Accompanying drawing is the structural representation (cross-sectional view) of the utility model.
Sequence number among the figure: the 1st, optical fiber, the 2nd, cover is moulded layer (cover is moulded the pipe layer), the 3rd, aramid fiber layer, the 4th, light unit restrictive coating, the 5th, conductor, the 6th, insulating barrier, the 7th, belting layer, the 8th, lining material layer, the 9th, lock armo layer.
Embodiment
To combine embodiment (accompanying drawing) to further describe below the utility model:
As shown in the figure, the couplet armour photoelectric comprehensive power cable of the utility model comprises the light unit cable core that adopts fiber optic materials to be prepared from, around some electric power cable cores of light unit cable core setting and be wrapped in the outer belting layer 7 of electric power cable core, lining material layer 8, lock armo layer 9 successively; Said lock armo layer is to buckle the helix tube that forms by metal tape (galvanized steel strip, stainless steel band, aluminum alloy strip etc.) edge to constitute; Said smooth unit cable core is by some optical fiber 1 and is wrapped in the outer cover of optical fiber successively and moulds layer (cover is moulded the pipe layer) 2, aramid fiber layer 3 that light unit restrictive coating 4 is formed.
More specifically say: the fiber count described in the utility model is: 2 ~ 48 cores.The cable core of power cable is the insulated wire cores of conventional structure, is looped around around the light unit cable core according to 20 ~ 40 times pitch of the outer warp of cable core.The nominal cross of electric-cable core conductor 5 can be 1.5 mm
2, 2.5 mm
2, 4 6mm
2, 10mm
2, 16mm
2, 25mm
2, 35mm
