What Causes Poor Quality Neoprene Zipper Cable Sleeves

The Neoprene Zipper Cable Sleeve is made of environmentally friendly PET and other materials, and has good wear resistance, expandability, smoothness, flame retardancy and air permeability and heat dissipation performance. The product is commonly used in the maintenance and decoration of electrical products such as computer power lines, audio and video lines, lighting, central air conditioners, refrigerators, automatic washing machines, and optical cables, motorcycles, vehicles, and airports. It is required to use brushed or three-wire neoprene zipper cable sleeves with different widths, colors and patterns.

Common reasons for the failure of general neoprene zipper cable sleeves:
1. The first is the problem of the material itself. If the recycled granules are used to produce PET yarn, it is generally not heat-resistant, and the weaving equipment is uneven and has no gloss.
2. In the production process, the yarn was not paid attention to, resulting in one or two yarns not being aligned neatly in the middle, and yarn skipping will occur during knitting.
The key factors of the quality of neoprene zipper Cable Sleeve cable accessories are diversified, generally there are several levels as follows:
1. Performance of electrical equipment. The performance of electrical equipment is the main criterion for evaluating the quality of cable accessories. It mainly considers whether the electromagnetic field distribution of the cable accessories is effective, whether the method of improving 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 electrical properties must also be considered, including the chemical and physical properties and structural stability of cable accessories, such as whether the stress control material performance is stable, whether the stress 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 materials fusion, the stability of 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 transmission and release, thermal expansion and contraction on the electrical properties of each component and mechanical equipment performance interference etc.
2. Sealing performance. The sealing and waterproof performance directly affects the performance and service life of the electrical equipment of the cable accessories. Whether the sealing structure of the terminal equipment is reliable and stable. Generally speaking, the intermediate joint should also have a corresponding metal material waterproof casing, especially for direct burial or application in humid environments.
3. Mechanical equipment performance. The terminal equipment should have sufficient bending strength and anti-seismic working ability. The intermediate joint should be able to bear a certain tensile strength and prevent damage from external forces.
4. Processing technology performance. The performance of processing technology is an important criterion for the design scheme and model selection of cable accessories. The installation process should be as simple as possible, which is conducive to on-site construction and the construction period is short; the requirements for the on-site environment and the technical strength of employees are not high; the assembly quality is very easy Control, reliable quality, etc.
5. Manufacturer's quality assurance system. When the prefabricated component cable accessories leave the factory, the manufacturer provides plastic prefabricated components, prefabricated component ground 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 assembly process of each component are directly related to the final quality of the product.
