High Voltage Cable Joint

Reynolds has some series of. Single pin and multipin high Voltage connectors.

If you want to make high voltage joints the following is important.

Take care of equally distribution of the electrical field.

Avoid sharp edges at the high Voltage side and at the grounded side. They will disturb uniform distribution of the electrical field.

If sharp edges cannot be avoided, place a corona shield around those objects.

Corona shields can be made of insulating material with a high dielectric constant. Sharp edges can be improved just by putting blob of silicone compound on the sharp ends.

Use long surface ways. The photograph below shows a single pin high Voltage connector made of silicone rubber.

When assembled there is no air between the walls of the two parts.

Try to avoid ionization and corona effects. If low ionization occurs, remove the ionized air by ventilation.

Insulation can be improved by immersing the circuit in oil or dielectric fluid.

Fixed joints can be covered with RTV silicone compound.
