Drawings
Fig. 1 is a cross-sectional view of an optical cable special for a nuclear radiation resistant nuclear power station according to the embodiment of the present invention.
Detailed Description
The present invention will be further described with reference to the following detailed description of preferred embodiments thereof, which is to be read in connection with the accompanying drawings.
First, the optical cable special for nuclear power plant with nuclear radiation resistance according to the embodiment of the present invention will be described with reference to fig. 1, and the application scenarios are wide.
As shown in figure 1, the utility model discloses special optical cable of nuclear power station of nuclear radiation resistance has many cable cores 1, enhancement layer 2, filling layer 3, oversheath 4.
Specifically, as shown in fig. 1, a plurality of cable cores 1 are twisted in a star shape, and each cable core 1 comprises an optical fiber 11, a cladding 12, an oxidation preventing layer 13 and a tight cladding 14 from inside to outside.
Further, in the present embodiment, the optical fiber 11 is made of high-purity silica, and the purity of the silica material is not lower than 99.9999%. Further, in this embodiment, the cladding 12 is made of fluorine-doped silica, the oxidation preventing layer 13 is coated on the cladding 12, the oxidation preventing layer 13 is made of an ultraviolet curable coating, and the tight cladding 14 is made of aramid fiber.
Specifically, as shown in fig. 1, the reinforcing layer 2 covers the plurality of cable cores 1, in this embodiment, the reinforcing layer 2 is helically twisted outside the plurality of cable cores 1, and in this embodiment, the reinforcing layer 2 is made of aramid fibers.
Because the tight covering layer 14 and the reinforced layer 2 select aramid fiber, the radiation resistance of the optical cable is greatly improved, the cost performance is high, the cost is saved, meanwhile, the specific modulus of the aramid fiber is moderate, the linear expansion coefficient is small, the flexibility of the optical cable is greatly improved, and the optical cable can be repeatedly wound and released.
Specifically, as shown in fig. 1, the filling layer 3 is filled between the cable core 1 and the reinforcing layer 2, and in this embodiment, the filling layer 3 is made of high temperature resistant silicone, so that the thermal resistance is improved, and the cable is stretch-proof and wear-resistant.
Specifically, as shown in fig. 1, the outer sheath 4 covers the reinforcing layer 2, and the outer sheath 4 is made of a thermoplastic elastomer.
Above, with reference to fig. 1, the optical cable special for nuclear power plant with anti-nuclear radiation according to the embodiment of the present invention is described, which is not only anti-radiation, but also stretch-proof and wear-resistant, and moreover, can be repeatedly retracted and deployed, and has good flexibility.
It should be noted that, in the present specification, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention. Numerous modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the foregoing description.
