The utility model discloses a cable transit for a drilling platform, which comprises a round pipe fixedly mounted on a deck, wherein, a flange is fixedly mounted at the upper end of the round pipe, and a stuffing box is arranged on the flange. By controlling the number of pipe holes on the stuffing box, the utility model effectively solves the problem that a multi cable transit is too costly and inconvenient to use when cables penetrating the deck face are of a relatively small number. Compared with like cable transits, the utility model has the advantages of convenient construction, low cost and the like.
