How to maximize the shielding layer of drag chain cables?

1. Sufficient shielding to meet usage needs

In ordinary usage environments, electromagnetic interference can reduce the transmission efficiency of signals. Generally speaking, using shielded drag chain cables with metal foil can provide sufficient noise protection. But in environments with severe noise, shielded cables that combine woven mesh and metal foil can be used.

2. Choose appropriate shielding for specific environments

In the process of repeated bending, spiral wound shielding cable layers are usually used, and bent cables should be avoided as much as possible, as bent cables may tear the foil layer, weaken the shielding effect or disappear directly.

3. Grounding requirements

In order to meet the grounding requirements of the equipment connected to the drag chain cable, it is necessary to use a large area of shielding layer as much as possible, and check whether the connection between the grounding point and the shielding cable is tight, whether electromagnetic noise can be effectively eliminated, and most importantly, whether the low resistance resistance of the cable grounding path is excellent.

Of course, in order to maximize the effectiveness of the shielding layer, the most important thing is to start from the source. The appropriate production materials, processes, and usage scenarios are the best. After selecting the cable, it is necessary to set up an appropriate grounding method. During use, attention should be paid to the operation method, and there should be no violent dragging or other actions that can cause significant damage to the cable. It is also important to avoid the environment of the supermarket, pay attention to protection during transportation, reduce friction with the contact surface, extend the service life of the cable, and further enhance the effectiveness of the shielding layer.
