This paper describes dielectric strength of oil immersed insulation for DC voltage and it's polarity reversal voltage. Dielectric strength for polarity reversal voltage is a key point to rationally design HVDC insulation system. Authors investigate the breakdown characteristics of creepage insulation structures for DC and polarity reversal voltages. Especially, the partially concentrated stress at distant portion from the electrodes is investigated in compared with the stress near the electrodes.<br> As the results, it is clarified that the partially concentrated stress at distant portion from the electrode does not necessarily cause the initiation of breakdown. The stress near the electrodes tends to initiate breakdown for DC voltage. The creepage insulation is not much affected by the polarity reversal voltage.<br> These results in this paper are applied to optimum insulation design of the oil immersed 500kV HVDC apparatus in Kiisuidou Project.
