<p>PURPOSE:To realize easy and reliable operation and to shorten the work time by enclosing a resin powder having high water absorbing power in a water permeable bag and coupling a linear body, to be pulled into an electrical piping, directly or indirectly to one end of the bag. CONSTITUTION:A water eliminator for electrical piping 8 comprises a resin powder 2 having high water absorbing power encapsulated in a water permeable bag 1, which is normally flat but expands into gas cylinder shape or cylindrical shape, and a linear body 5 coupled to one end of the bag 1. The water eliminator 8 is pulled in a piping 4 while sliding thereon. When the bag body 1 contacts with water 12 stored at a curved part of the piping 4, the resin powder 2 in the bag body 1 absorbs the water to expand into basket shape. If thus pulled out bag body 1 has outer diameter approximately same as the inner diameter of the piping 4 it means that the water still remains in the piping 4, whereas when the outer diameter of the bag body 1 is considerably smaller than the inner diameter of the piping 4 it means that the water is eliminated sufficiently.</p> |
