Problems solved by technology

Using steel wire as the strengthening core wire of the optical cable can increase the strength of the optical cable, but due to the poor corrosion resistance of the steel wire, it will rust after two years of use, produce harmful gases, cause hydrogen loss, and affect the propagation performance of the optical fiber
Due to the strong electrical conductivity of the steel wire, under the influence of high voltage and lightning, an induced current will be generated, which will also affect the performance of the optical cable.
In short, the service life of this steel wire reinforced core is not long

Abstract

The invention relates to a glass fiber reinforcement core used for increasing cable strength and a production method of the glass fiber reinforcement core, and belongs to the technical field of optical fiber. The production method comprises the following steps of: placing epoxy vinyl ester resin, curing agent BPO, curing agent TBPB, release agent PUL24 and fillers in a liquid tank, and uniformly stirring the components to obtain a resin mixed solution; heating a mould to be used, and stranding glass fibers to a necessary line diameter; and passing the stranded glass fibers through the liquid groove filled with the resin mixed solution, and passing the stranded glass fibers through the heated mould, demoulding, towing and winding the demoulded cable to obtain the cable reinforcement core. The cable reinforcement core provided by the invention is prepared with the glass fibers and the epoxy vinyl ester resin as main raw materials, so that the cable reinforcement core is non-conductive and is not affected by high pressure electricity or thunder and lightning. Therefore, the service life is long.

Description

technical field [0001] The invention relates to a glass fiber reinforced core for increasing the strength of an optical cable and a production method thereof, belonging to the technical field of optical fibers. Background technique [0002] In order to increase the strength of the optical cable, reinforcing core wires are arranged in the optical cable. At present, steel wires are widely used as the reinforcing core wires of optical cables. Using steel wire as the strengthening core wire of the optical cable can increase the strength of the optical cable, but due to the poor corrosion resistance of the steel wire, it will rust after two years of use, produce harmful gases, cause hydrogen loss, and affect the propagation performance of the optical fiber. Due to the strong electrical conductivity of the steel wire, under the influence of high voltage and lightning, an induced current will be generated, which will also affect the performance of the optical cable. In short, the...
