Reasons for Poor Quality of Pattern Braided Sleeve

Pattern Braided Sleeve are made of environmentally friendly PET and other materials and have good wear resistance, expandability, smoothness, flame retardancy and breathability and heat dissipation properties. Products are commonly used in the maintenance and decoration functions of computer power cords, audio and video cables, lighting, central air conditioners, refrigerators, automatic washing machines and other electrical products as well as fiber optic cables, motorcycles, vehicles, airports and other routes. They can be customized according to customer requirements. It is required to use brushed or three-wire knitted sleeves with different widths, different colors, and different patterns.

1. Common causes of defects in general pattern knitted sleeves:
①The first is the problem of the material itself. If the PET filament is produced from recycled particles, it is generally not heat-resistant, and the woven equipment is uneven and has no gloss.
② During the production process, the yarn was not paid attention to, resulting in one or two yarns in the middle not being aligned neatly, and yarn skipping would occur during knitting.
2. The key factors for the quality of Pattern Braided Sleeve cable accessories are diverse. Generally, there are the following aspects:
①Electrical equipment performance. The performance of electrical equipment is the main criterion for evaluating the quality of cable accessories. Mainly consider whether the electromagnetic field distribution of the cable accessories is effective, whether the method to improve the electrostatic field distribution is appropriate, the electrical strength of the material, the dielectric loss and the insulation margin of the product, etc. At the same time, the stability of the electrical properties must also be considered, including the chemical, physical properties and structural stability of the cable accessory materials, such as whether the performance of the geostress control material is stable and whether the geostress cone is easy to deform. The harm of cable insulation shrinkage to the electromagnetic field distribution of cable accessories and the countermeasures to avoid it, the compatibility of various material fusions, the stability of fusion page performance, etc. In addition, the thermal properties of cable accessories should also be considered, such as dielectric loss, loop resistance and stability of conductor connections, heat transmission and release, and the impact of thermal expansion and contraction on the electrical properties of each component and mechanical performance. Interference etc.
②Sealing performance. The sealing and waterproof performance directly affects the performance and service life of electrical equipment of cable accessories. Is the sealing structure of the terminal equipment reliable and stable? Generally speaking, the intermediate joint should also have a corresponding metal waterproof casing, especially if it is directly buried or used in a humid environment.
③Mechanical equipment performance. Terminal equipment should have sufficient bending strength and earthquake resistance. The intermediate joint should be able to withstand a certain tensile strength and have measures to avoid damage from external forces.
④Processing performance. Processing performance is an important criterion for the design and model selection of cable accessories. The installation process should be as simple as possible, which is conducive to on-site construction and has a short construction period; the requirements for the on-site environment and the technical strength of employees are not high; the assembly quality is very easy Operation, reliable quality, etc.
⑤Manufacturer`s quality assurance system. When the prefabricated component type cable accessories leave the factory, the manufacturer provides plastic prefabricated components, prefabricated component in-situ stress cones, porcelain sleeves, casings, prepregs and other parts, which are then assembled into overall terminal equipment or connectors during on-site assembly. , Therefore, the manufacturing quality and installation process of each component are directly related to the final quality of the product.
