What are the key safety protection components of an electric vehicle charging cable, and what functions do they serve?

While every component contributes to overall safety, the combination of conductor-connector connections and insulation layers is most critical.
Loose or high-resistance terminal connections generate excessive heat during charging, which is a leading cause of charging failures and safety risks. At the same time, degraded or damaged insulation can cause current leakage and short circuits. This is why Degson places special emphasis on ultrasonic welding technology for terminal connections and strict insulation material testing — addressing both primary safety risk points at their source.
