Method and arrangement for determining pressure tightness of a pressure-tight cable feed-through

摘要

For the purpose of testing the pressure tightness, a pressure-tight passageway with a frame 1, whose opening is filled with conductors 3 to be put through the passageway, and pieces of packing 2 surrounding each cable, along with an arrangement for compressing the block formed by the packing pieces, is provided with a channel-forming layer 4 conducting pressurised fluid that is formed inside this block, lying in a plane at right angles to the laying of the conductors 3 through the block, and it is connected 5, 6 to a source of pressure fluid.
