Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an electromagnetic interference-proof flexible oil-resistant cable. Background Art

[0002] Cables are widely used in various fields, including power, communications, and industrial control. However, in certain environments, cables may be affected by electromagnetic interference, oil corrosion, and rodent gnawing, which can lead to unstable signal transmission, cable damage, and even safety accidents.

[0003] Electromagnetic interference (EMI) refers to the effect of external electromagnetic fields on cables during signal transmission, potentially leading to signal distortion and bit errors. This is unacceptable in applications requiring high signal accuracy, such as medical equipment and precision instruments. Furthermore, in industrial environments, cables are often exposed to oil and dirt, which can cause aging and cracking of the cable sheath, reducing the insulation performance and service life of the cable. Therefore, we have developed an EMI-resistant, flexible, oil-resistant cable to address this issue. Utility Model Content
