PVC electrical tape is an important necessity in electrical work, and one of its major functions is to protect line insulation. Therefore, we must also pay attention to the insulation performance when purchasing PVC electrical tape. So, how do we quickly judge whether PVC electrical tape has superior insulation performance when purchasing it? According to Guangzhou ruidetai Electrical Equipment Co. , Ltd. , there are many kinds of PVC electrical tapes on the market. However, different brands of PVC electrical tapes have different insulation properties due to different production processes. This also caused great trouble to PVC electrical tape purchasing personnel, how to quickly judge whether the insulation performance of PVC electrical tape is superior has become one of the skills that many PVC electrical tape purchasers must master. Guangzhou ruidetai Electrical Equipment Co. , Ltd. believes that the superiority of the insulation performance of PVC electrical tape can be quickly judged by stretching the PVC electrical tape and observing whether the surface of the tape is consistent in color. In general, after stretching PVC electrical tape, the appearance and surface color of the tape are consistent, so the insulation performance of the PVC electrical tape will be better. However, after the general inferior PVC electrical tape is stretched, the appearance surface of the PVC electrical tape will appear anti-white phenomenon. The more obvious the anti-white phenomenon is, the worse its insulation performance will be.
