直达电动分配系统和电动汽车的传播导致对尺寸较小，更安全和可靠性的直流电路HVC的需求增加。这款最近开发的密封高压HVC的接触块位于密封的胶囊中，该胶囊带有断裂气体，以提高断裂性能，较小的尺寸和高接触可靠性。

Even in the event that overcurrent is generated by short circuit due to failure or malfunction, the original contact structure maintains its contacting point contact state, and this enables it to achieve the industry’s highest overcurrent withstand capability of 20,000 A, while significantly reducing the risk of fire and explosion. Furthermore, it also achieves non-polarization for the main circuit and a consistent forward and reverse direction breaking performance.
