Nowadays, ultra-high voltage direct current transmission lines UHVDC –TL are widely used and constructed to transmitted powers for a very long distance and across different topologies. UHVDC-TL have very high towers and wide lightning induced area, the operation voltage is very high which increase the probability of lightning striking to UHVDC transmission lines. The shielding failure occurs when a lightning bypasses the overhead ground wires and stroke the phase conductors. The correct design to improve the shielding effect of transmission line to lightning is one of the key problems of transmission line design. This paper discuss shielding failure of UHVDC ((800 kV transmission lines. An electromagnetic model of transmission line and lightning leader is constructed to study the transmission line voltage effects. This paper aims to study the shielding failure of UHVDC (800 kV transmission line by using charge simulation method. The attractive areas around UHVDC-TL due to lightning leader are detected. The range of lightning current striking the phase conductor is obtained, and the shielding failure probability of transmission line is calculated. From the calculated results, the voltage and polarity of transmission line effect on striking distance. For negative lightning leader, the striking distance of transmission line pole increases around positive pole and decreases around negative pole. In spite of this the striking distance of the transmission line ground wire doesn’t have a big effect due to UHVDC-TL voltages
