| Abstract: | he obstacle caused by frozen protective steel tubes of straight-buried cable is one of the most common cable obstacles in winter. The paper analyzes the functions of foamed rubber and puts forward that the cable obstacles can be prevented effectively by the use of foamed rubber’s compressible characteristic for absorbing water, lightening the pressure and enlarging the volume as a result of freezing expansion in protective steel tubes of straight-buried cable. |
| Keywords: | cable protective steel tubes freezing expansion foamed rubber |
