Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
A kind of all dielectric high intensity central beam tube type optical fiber ribbon cable provided by the utility model, as shown in Figure 1-2, including light
Fibre ribbons stack 1, the outside of fibre ribbon stack 1 are coated with plastic tube 2 made of polybutylene terephthalate (PBT), and fibre ribbon is folded
Body 1 can be freely movable in plastic tube 2, and the gap between fibre ribbon stack 1 and plastic tube 2 is filled with fine cream 3, plays what is blocked water
Effect；The outside of plastic tube 2 is coated with one layer of blended fabric 4, blended fabric 4 by warp-wise the He of aromatic polyamide fibre yarn 7
The shuffling of PET polyester fibers 8 of broadwise forms, its length of aromatic polyamide fibre yarn 7 along optical cable in cladding of blended fabric 4
Direction coats, and to ensure tensile strength, is made up of in an aromatic polyamide fibre yarn 7 hundreds of filaments, yarn it is strong
Degree can reach 100N, wrap up the quantity foundation light of the aromatic polyamide fibre yarn 7 contained by the blended fabric 4 used in an optical cable
Cable diameter is 20-30 roots, and the maximum tensile strength of blended fabric 4 can reach 2000-3000N；Aromatic polyamide fibre
