What are the reasons for the poor quality of PP Zipper Braided Sleeve?

The PP Zipper Braided Sleeve is made of environmentally friendly PP and other materials, which has good wear resistance, ductility, smoothness, flame retardant grade, and breathable and heat dissipation performance. Products are often used in computer power lines, audio and video lines, lighting, refrigerators, automatic washing machines and other electrical products, as well as maintenance and decoration effects of optical cables, motorcycles, vehicles, airports and other lines. Brushed or three-lines with different total widths, different colors, and different patterns can be made according to customer requirements.

1. The common causes of bad PP Zipper Braided Sleeve are as follows
① The problem of the material itself. If the PP filament produced by granules is generally not heat-resistant, the equipment prepared is uneven and has no gloss.
②In the production process, the yarn is not paid attention to, resulting in one or two yarns in the middle not being drawn neatly, and yarn skipping will occur in the case of weaving.
2. The key factors for the quality of PP Zipper Braided Sleeve and cable accessories are diverse. In general, there are the following levels.
① The performance of electrical equipment and the quality of electrical equipment are the main criteria for evaluating the quality of cable accessories. Focus on considering whether the electromagnetic field of the cable accessories is useful, whether the method of improving the electrostatic field is appropriate, the compressive strength of the raw material electrical equipment, dielectric loss, and the insulation margin of the product, etc. At the same time, the stability of electrical properties should also be considered, including the organic chemistry, physical properties and structural stability of raw materials for cable accessories. For example, whether the performance of the raw material controlled by the ground stress is stable, whether the ground stress cone is easy to deform, the damage of the cable insulation shrinkage to the electromagnetic field distribution of the cable accessories and its avoidance measures, the compatibility of various materials, the stability of the fusion page performance, etc. In addition, the thermal performance of cable accessories should also be considered, such as dielectric loss, loop resistance and stability of electrical conductor connection, heat transfer and release, thermal expansion and contraction on the electrical performance of various components and mechanical equipment performance.
② Sealing performance, sealing and waterproof performance directly affect the performance and service life of electrical equipment of cable accessories, and whether the sealing structure of terminal equipment is reliable and stable. In general, the intermediate joints should also have a consistent metal waterproof casing, especially when directly buried or applied in a humid environment.
③ mechanical equipment performance. The terminal equipment should have sufficient bending strength and anti-seismic working ability, and the intermediate joint should be able to withstand a certain tensile strength to avoid external damage.
④ Processing technology performance, which is the main criterion for selecting the design scheme and model of cable accessories. The installation process should be as simple as possible, which is conducive to on-site construction, short construction period, low requirements on the site environment and technical strength of employees, easy assembly quality, and reliable quality.
⑤Quality assurance system for PP Zipper Braided Sleeve. When prefabricated cable accessories leave the factory, plastic prefabricated components, ground stress cones, porcelain bushings, sleeves, prepregs and other parts of prefabricated components are given, and then assembled into overall terminal equipment or connectors during on-site assembly. Therefore, the manufacturing quality and installation process of each part is directly related to the quality of the goods.
