Abstract A rectifying bridge for a high voltage DC power transmission system comprises a plurality of rectifiers connected in two groups in each AC phase in a respective bridge arm thereof. A platform supports the rectifiers in two rows and the platform is electrically connected to the lower potential bridge pole so as to be at a potential between the higher potential bridge pole and earth potential. The rectifiers at the ends of both rows are electrically connected to the higher bridge pole, while the intermediate rectifiers in each row, between the endmost rectifiers, are electrically connected to the platform. The spacing between adjacent rectifiers is at least as great as the minimum spacing to prevent discharge therebetween.
