Abstract

The invention relates to the technical field of power tubes, and particularly to a lightning-proof optical fiber communication pipeline and a preparation method thereof. The lightning-proof optical fiber communication pipeline in the invention comprises a body, wherein the outer surface of the body is coated with an insulation shielding layer with a thickness of 6-8 mm, the insulation shielding layer is prepared from a shielding filler, and the shielding filler comprises 10-15 parts of modified ceramic, 4-6 parts of flaky nanometer aluminum nitride and 3-5 parts of modified silk mica. The lightning-proof optical fiber communication pipeline prepared by the invention can bear instantaneous lightning voltage in the use process, has a good lightning-proof effect, and also has good flame retardant property.

Description

technical field [0001] The invention relates to the technical field of power pipes, in particular to a lightning-proof optical fiber communication pipe and a preparation method thereof. Background technique [0002] Communication lines are responsible for the important task of transmitting information. With the continuous development of communication technology, it has become an inevitable trend to use more and more optical fibers on communication lines. Our country has a vast territory and complex landform structure, and it is a place where natural disasters frequently occur. Especially in some parts of the south of our country, due to frequent lightning, the degree and frequency of lightning disasters have been ranked among the top in the world. One of the worst natural disasters. It is known that the phenomenon of damage to communication lines caused by lightning strikes occurs frequently in our country every year, which has brought great losses to the country and people...
