Glass fiber reinforced plastic round bar applied to lightweight all-dielectric aerial optical cable

Abstract

The invention discloses a glass fiber reinforced plastic round bar applied to a lightweight all-dielectric aerial optical cable. The glass fiber reinforced plastic round bar armors the outer layer ofa cable core and is manufactured from the following components: 70-80 parts of a vinyl resin, 5-10 parts of a thermoplastic polyurethane elastomer, 5-15 parts of a fluorine-containing polymer, 90-160parts of glass fibers, 5-12 parts of a coupling agent and 10-20 parts of an impregnating compound. According to the glass fiber reinforced plastic round bar applied to the lightweight all-dielectric aerial optical cable disclosed by the invention, glass fiber reinforced plastic is excellent in strength, corrosion resistance and weather resistance, and can meet the requirements on the lightweight all-dielectric aerial optical cable.

Description

technical field [0001] The invention relates to the field of communication materials, in particular to a glass fiber reinforced plastic round rod used in light-duty all-dielectric aerial optical cables. Background technique [0002] There are two types of optical cable designs for traditional rodent and bird protection: chemical methods and physical methods. The chemical method is generally to add repellants such as capsicum to the outer sheath material, so that rodents and birds do not like to damage the outer sheath of the optical cable, thereby protecting the optical cable from damage; or the outer sheath Designed with colors that birds do not like, etc., but these methods have limited effects, and are likely to cause pollution to the production and use environment, and the taste of capsicum will weaken or even disappear over time, and the warning color will age and fade, making the protective effect more effective. It's getting worse. [0003] The physical method is ge...

[0003] The physical method is generally to add a metal protective layer such as round steel wire spiral armor or stainless steel tape armor in the outer sheath to protect the outer sheath of the optical cable so hard that it is not easy to be damaged. This method is currently a more reliable anti-bite method, but the use of metal protective layers such as steel wire armor or stainless steel tape armor not only deteriorates the bending performance of the optical cable, but also greatly increases the weight and outer diameter of the optical cable, and also increases the difficulty of production, construction and use of the optical cable. Moreover, it is not suitable for overhead laying due to its large weight and high cost, and it is not suitable for areas where lightning strikes frequently occur.
