Drag chain cable has been very popular in industrial production and machine manufacturing industry, but in many working occasions, because of the interference factors from the inside and outside of the cable, it is necessary to add a shielding layer to the drag chain cable to reduce the interference of external signals, so as to improve the use performance of the cable. So how can we maximize the role of shielding layer? Yichu cable is analyzed from three aspects.

1. Enough shielding to meet the use requirements

In the common use environment, electromagnetic interference will reduce the signal transmission efficiency. Generally speaking, the use of metal foil type shielded drag chain cable can provide enough noise protection. However, in the environment with serious noise, the shielded cable with combination of woven mesh and metal foil can be used.

2. Select appropriate shielding in specific environment

In the process of repeated bending, the spiral wound shield cable layer is usually used, and the bent cable is avoided as far as possible, because the bent cable may tear the foil layer, making the shielding effect weaken or disappear directly.

3. Grounding requirements

In order to meet the grounding requirements of the equipment connected with the drag 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 the electromagnetic noise can be effectively eliminated, the most important point depends on whether the low resistance of the cable grounding path is good.

Of course, in order to maximize the role of shielding layer, the most important thing is to start from the source, production materials, production technology, use occasions, and appropriate is the best. After the cable is selected, proper grounding mode shall be set. During the use, attention shall be paid to the operation mode to avoid violent dragging and other actions that may cause great damage to the cable. In addition, the supermarket environment shall be avoided as far as possible. During the transportation, attention shall be paid to the protection to reduce the friction with the contact surface and extend the service life of the cable, so as to further say that the function of the shielding layer can be played better.
