As an important component to ensure the safety of line connections in the power field, the cable joint box's operation stability will directly affect the reliability of the entire power system. However, there are often many buyers in practical applications who encounter various failures due to improper selection, product quality defects or installation problems, which can not only easily lead to project delays, increased operation and maintenance costs, but may also cause safety accidents. Therefore, in this article, I will help you sort out the common problems of cable joint box and tell you how to choose the right cable joint box.
From the perspective of practical application scenarios, the most prominent problem of cable joint box is the failure of the seal, which is also the main cause of line failure. In outdoor, underground pipe corridors, or coastal high-humidity environments, if the sealing structure design of the cable joint box is unreasonable and the weather resistance of the sealing material is insufficient, water vapor, dust, or corrosive media will gradually invade the inside of the box, resulting in oxidation and corrosion of the metal terminals and deterioration of insulation properties. In addition, some low-cost connector boxes adopt a single sealing structure. Under long-term mechanical vibration and temperature changes, the sealing surface is prone to gaps, which further exacerbates the risk of sealing failure. This is a huge hidden danger for manufacturing, data centers and other scenarios that rely on continuous power supply.
Insufficient insulation performance is another type of high-incidence problem of cable joint box, and this type of hazard is usually concealed. When the dielectric loss of the insulating material of the cable joint box exceeds the standard or the design of the insulating partition in the box is unreasonable, the electric field distribution at the joint will be uneven, and partial discharge may be caused after long-term operation, which will not only accelerate the aging of the insulating layer, but may also penetrate the insulating structure, causing leakage or short circuit.
In addition, the poor adaptability of the cable joint box and the complex installation problems will also cause a lot of troubles to buyers. In different projects, there are differences in the material, cross-sectional area, and voltage level of the cables. If the specifications of the cable joint box are single and cannot be flexibly adapted to different types of cables, the connection may be loose or the contact resistance is too large, and the joule heat generated during operation will also exacerbate the joint loss. At the same time, some cable joint boxes require professional tools and skilled technicians to complete the installation. In overseas projects, the skill level of the local construction team is uneven, and the complex installation process will not only prolong the construction cycle, but may also cause hidden faults due to improper operation.
