A cylindrical oil tank for stepping switches of stepping transformers, whose housing wall consists of a hollow wound body consisting of threads which are wound in the form of crossing layers. The housing wall carries a plurality of contacts at different electrical potentials, both in a plane of the cylinder and in at least one further plane, which contacts are inserted into holes or recesses in the housing wall. The winding angle of the resin-impregnated threads is dimensioned such that each thread which runs into a hole of a contact runs past each hole of an adjacent contact at a different potential. |
