Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1 and Fig. 2, the embodiment of the present invention includes:
Embodiment 1
A kind of crosslinked polyetylene insulated optical fiber composite submarine power cable, including cable core, light unit 10, reinforced packing 8, band 9, inner liner 11, armor 12 and serving 13.
Described cable core has 3, and is distributed in star, and band 9 is around the periphery wrapping in cable core.Reinforced packing 8 is filled in the cable core gap inside band 9, is provided with preformed hole 14, and light unit 10 is placed in preformed hole 14.On the one hand this reinforced packing 8 is PP material, and material is hard, is unlikely to deform, and it is filled in the stranding gap of product, can ensure that the product after stranding is closely knit, rounding；On the other hand play protection and the effect of fixing light unit, and ensure that light unit is not damaged in laid processes.It addition, the size of the aperture ratio light unit 10 in reinforced packing internal reservation hole 14 wants big, which ensure that light unit in reinforced packing can relative movement, when product is when being bent, and light unit will not be damaged.
The most wrapped described inner liner 11 in outside, armor 12 and the serving 13 of described band 9.Wherein, armor 12 is zinc-coated wire, and inner liner 11 and serving 13 are the PP rope that Colophonium is cementing.
