Problems solved by technology

When stainless steel strips are welded, there is an instantaneous high temperature, so the fiber paste should have a higher dropping point and flash point; due to the incompatibility between the fiber paste and stainless steel and the hydrogen generated during the welding process, the presence of hydrogen will be adsorbed on the surface of the optical fiber, and the It will react in the fiber to generate OH groups, or form defects in the fiber lattice, which will increase the loss of the fiber and affect the transmission performance of the fiber; in addition, the high and low temperature performance of the fiber paste also directly affects the transmission performance of the fiber

Abstract

The invention relates to hydrogen absorption fiber paste for an optical fiber composite overhead ground wire (OPGW) optical cable. The hydrogen absorption fiber paste comprises, by weight, 75-85% of base oil, 6-10% of gelatinizing agent, 0.3-0.6% of antioxidant, 0.8-1% of viscosity index improver, 1.5-2% of oil distribution inhibitor and 2-5% of hydrogen absorption agent. The base oil is polyalpha-olefin synthesis oil, and the gelatinizing agent is a composite of an organic gelatinizing agent and an inorganic gelatinizing agent. The hydrogen absorption fiber paste has the advantages of adopting the polyalpha-olefin synthesis oil as the base oil so as to enable the fiber paste to have good high-low-temperature performance; improving the stability of a glue body by adding an appropriate amount of silicon-containing (inorganic) glue body into a silicon-free (organic) glue body; having good hydrogen absorption performance by adding an efficient hydrogen absorption agent, removing hydrogen caused by incompatibility of the fiber paste and stainless steel and caused in welding process, reducing defects in optical fiber lattice and loss of optical fiber, and improving transmission performance of the optical fiber.

Description

technical field [0001] The invention relates to optical fiber technology, in particular to a hydrogen-absorbing fiber paste for OPGW optical cables and a manufacturing method thereof. Background technique [0002] OPGW (Optical Ground Wire), that is, optical fiber composite overhead ground wire, it is a form of optical cable structure that combines optical fiber and overhead ground wire, and it is used on high-voltage transmission and distribution lines. Among them, the optical fiber uses the difference in refractive index between the core and cladding materials to transmit light energy in the optical fiber. In addition, because the optical fiber has the characteristics of anti-electromagnetic interference and light weight, it can be installed on the top of the transmission line tower without considering the best hanging position and electromagnetic corrosion. [0003] This kind of optical cable in the form of OPGW combines the two functions of grounding and communication. ...
