Double steel wire mesh power cord elevator cable manufacturers tell you that cable accessories are an indispensable part of power transmission lines, as cable-related products. Play the role of connecting and transferring power. Once a problem occurs in this link, it will inevitably cause power interruption, affecting the operation of society and causing unnecessary losses. Double steel wire mesh power cord elevator cable manufacturers tell you that cable accessories are of limited value, but they play a pivotal role. So how to choose high-quality cable accessory products? I think there are the following points for your discussion and analysis.
1. Electrical performance. The manufacturer of Double steel wire mesh power cord elevator cable tells you that the electrical performance is the primary principle for judging the quality of cable accessories. The main consideration is whether the electric field distribution of the cable accessories is reasonable, the electric strength of the material, the dielectric loss and the insulation margin of the product, and whether the measures to improve the electric field distribution are appropriate. At the same time, the stability of electrical properties must also be considered, including the chemical, physical and structural stability of the cable accessory materials, such as whether the performance of the stress control material is stable, the compatibility of the combination of various materials, and the cable insulation shrinkage to the cable The influence of the electric field distribution of the accessories and preventive measures, combined with the stability of the interface performance, whether the stress cone is easy to deform, etc. In addition, the thermal performance of cable accessories should also be considered, such as the contact resistance and stability of the conductor connection, dielectric loss, conduction release of heat, thermal expansion and contraction on the electrical and mechanical properties of each component, etc.
2. Mechanical properties. The manufacturer of Double steel wire mesh power cord elevator cable tells you that the terminal should have enough anti-bending and anti-vibration capabilities. The intermediate joint should be able to withstand a certain amount of tension and measures to prevent damage from external forces.
3. Sealing performance. Double steel wire mesh power cord elevator cable manufacturers tell you that the sealing performance directly affects the electrical performance and service life of the cable accessories. Whether the sealing structure of the terminal is stable and reliable. Generally speaking, the intermediate joint should also have a matching metal moisture-proof shell, especially for direct burial or use in a humid environment.
4. Process performance. The manufacturer of Double steel wire mesh power cord elevator cable tells you that process performance is an important condition for the design and selection of cable accessories. The installation process should be as simple as possible to facilitate on-site construction and short construction period; the requirements for the on-site environment and the technical level of workers are not High; the installation quality is easy to control, and the quality is reliable.
5. The manufacturer's product quality certification. Double steel wire mesh power cord elevator cable manufacturers tell you that when prefabricated cable accessories leave the factory, the manufacturer provides rubber prefabs, prefabricated stress cones, porcelain sleeves, shells, impregnating agents and other components, which are assembled into a whole when installed on site Terminal or joint, therefore, the manufacturing quality and installation process of each component are directly related to the final quality of the product.
