Can you build High-Voltage (HV) connectors above 3,000V?

Yes. For high-power umbilical applications, we can design High-Voltage Connectors rated for 3.3kV, 6.6kV, or higher. These custom designs feature extended Creepage and Clearance distances, specialized insulating materials, and corona-resistant potting to prevent electrical breakdown or arcing at depth.

High voltage underwater is risky.

  • Design Physics: We increase the physical distance between pins and the metal shell to prevent “Flashover.”
  • Partial Discharge (PD): We pay special attention to avoiding internal voids in the insulation, as these can cause Partial Discharge, leading to long-term insulation failure.
  • Testing: Custom HV connectors undergo Hi-Pot testing at significantly higher safety factors (e.g., 2x Rated Voltage + 1000V) to ensure absolute safety.
