When using the product after purchasing it, it is found that there will be some problems with the product, such as the soft connection of copper tape. Some products have been installed on the equipment for less than a month, and the copper skin on the surface has broken. What is the problem?

Is it because the product is bent and installed, or is the product frequently vibrated or moved?

1. The flexible connection of the copper tape installed by bending must be set to an incremental length. In this way, there will be a uniform gap between the copper strips after bending. On the one hand, the skin effect is good, and on the other hand, the heat dissipation is also fast.

2. If the copper foil soft connection vibrates frequently, it is recommended to increase the area of the contact surface during production. The most direct way is to increase the thickness of a single piece of copper foil, which can reduce the friction caused by the bolt during the process of excessive friction. To reduce the probability of rupture of copper foil, if there is budget space, use copper plates to fix the top and bottom, so that the effect is better.

Copper soft connection is welded by multi-layer copper tape or multi-strand copper wire braided wire. It is widely used in generators, transformers, switches, busbars, electrolysis, smelting and other high-current equipment for flexible conductive connections. Its functional advantages are as follows What time is it:

1. Make the conductive connection between high-current equipment more convenient, reliable and safe, and protect the related equipment from external forces.

2. Absorb the noise and vibration generated by the operation of high-current electrical equipment, and play an auxiliary role in heat dissipation.

3. It can avoid operation accidents caused by earthquakes and displacements in the surrounding environment.
