Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
Referring to Fig. 1 and Fig. 2, this utility model embodiment 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
In cable core gap inside band 9, being provided with preformed hole 14, light unit 10 is placed in preformed hole 14.This is reinforced fills out
Filling bar 8 is PP material, and material is hard, is unlikely to deform, and it is filled in the stranding gap of product, after on the one hand can ensureing stranding
Product is closely knit, rounding；On the other hand play protection and the effect of fixing light unit, and ensure light unit in laid processes not by
Damage.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 exists
In reinforced packing can relative movement, when product is when being bent, and light unit will not be damaged.
