The metallized electrodes adopt tiny fuses structure like picture 1. If there is any failure during capacitor operation, the power supply is automatically cut off by disconnecting the micro-fuse. In this way, the failure can be prevented and self-safety protection realized.

Pic.3 The red point is accident area. If any fault, the nearby fuse will immediately disconnect the circuit, playing the role of local protection.
Pic 3 After the failure of capacitor, the internal fuse will be completely disconnected and form open state.
