Description

Technical Field

With the large-scale application and replacement of products in the field of high pulse discharge, the demand for the use of coaxial cables is increasing, especially in the application scenarios of capacitor charging and discharging and high-voltage and high-current power transmission. Coaxial cable is not used for twisted pair cables, and the same wire exists in multiple connection layers. Therefore, it cannot adopt ordinary connection structure, because the strong short-circuit electric force in the test or product operation will cause the cable to be thrown off or the connection is not firm. The cable is easily affected by electromagnetic vibration. When high pulse and high current are passed through the cable, strong electromagnetic vibration will be generated regardless of high voltage or low voltage conditions. The connection between the cable and the equipment has poorer mechanical strength than other parts of the cable itself. Therefore, under the action of strong electromagnetic vibration, it will cause the internal connection layers of the cable to be easily misaligned or even peeled off, which will not only shorten the life of the cable, but also endanger personal safety in serious cases.
