Deck Winch SDW for Towed HV Power Cable IP66

Especially designed for temporary or stationary setup on seismic acquisition vessels in order to provide hoisting operations and towing seismic sources during geophysical surveys, the SDW deck winches for high-voltage cable line of a sound source (either a sparker or a boomer) are equipped with a high-voltage slip ring and water-resistant patch panel for connecting a deck cable. Depending on the model, a drum’s rotation can be provided manually or by means of an electric drive via a worm gearbox and chain transmission with the possibility of a smooth variation in rotational speed. The winch electrical equipment is housed in a special case with IP66 environmental protection.
