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 transmission performance of the optical cable.
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 high-strength optical cable filler and a preparation method thereof, and belongs to the technical field of optical cables. The preparation method comprises the following steps: putting high-temperature-resistant ethylene resin, a curing agent TBPO, a curing agent TBPB, a release agent PUL24 and a filler into a liquid tank, and uniformly stirring to obtain a resin mixed solution; heating a to-be-used mold, and taking glass fibers and strands to form a required wire diameter; enabling the stranded glass fiber wire diameter to pass through a liquid tank filled with the resin mixed solution, then enabling the stranded glass fiber wire diameter to pass through the heated mold, stripping the mold, and pulling and winding the stripped optical cable to obtain the high-strength optical cable filler. The high-strength optical cable filler disclosed by the invention is prepared by taking the glass fibers and the high-temperature-resistant ethylene resin as main raw materials, is high in impact strength and non-conductive, and is not influenced by high voltage and thunder and lightning. Therefore, the service life is long.

Description

technical field [0001] The invention relates to a high-strength optical cable filling material for increasing the strength of optical cables and a preparation method thereof, belonging to the technical field of optical cables. Background technique [0002] Optical cable filler is a component that fills the space in the cable core to keep it round during the stranding process. Most of the fillers for existing optical cables are solid ropes extruded from high-density insulating materials. The solid ropes consume a large amount of raw materials, have high manufacturing costs, and have high weight, resulting in high transportation costs for optical cables. In addition, the solid rope has high hardness, poor resistance to external force buffering, and poor protection effect. [0003] 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 ca...
