という問題点があった。[0003] Such a CATV coaxial cable is usually installed in a limited place of a distribution line support pole or a telephone line support pole, and due to its network property, in addition to a trunk line coaxial cable, a distribution coaxial cable. There are many sections with annex. However, when the distribution coaxial cable is installed together with the trunk coaxial cable, the self-supporting coaxial cable has no gap between the supporting wire and the coaxial cable, and thus the cable hanger cannot be used. When the distribution coaxial cable and the distribution coaxial cable are mounted together with a lashing wire, etc., the coaxial cable is provided with an aluminum sheath outer conductor, so that the cable habit is noticeable in appearance and is accepted as a construction method. There was a problem that it did not exist.

In the drawings, 1 is a supporting wire such as a galvanized steel stranded wire, and 2 is a trunk coaxial cable for CATV, for example. The support wire 1 and the coaxial cable 2 are arranged at intervals, and are integrated by a plastic mold 3 at appropriate intervals in the length direction. At this time, the length of the coaxial cable 2 with respect to the support wire 1 between the respective molds 3 is made longer according to the ratio of the difference between the temperature expansion / contraction rate of the support wire 1 and that of the coaxial cable 2.

FIG. 1 is a sectional view taken along the line 1- X 1 . Utilizing the space between the support wire 1 and the coaxial cable 2 of the pre-hanger type main body cable (see FIG. 2) installed in advance, insert the attachment part of the cable hanger 5 into this space to support the cable hanger 5 By attaching the cable 1 to the cable hanger 5, the other cable 4 gripped by the lower grip portion 5b of the cable hanger 5 can be hung and installed together with the trunk coaxial cable 2.

極めて効果的である。As described above, according to the method of using the pre-hanger type cable of the present invention, it is difficult to insert the cable hanger into the space between the support wire of the pre-hanger type main body cable and the main body cable. Another cable can be installed at a low cost in a short period of time. Therefore, for example, in the field of CATV, it is extremely effective if it is used when a distribution coaxial cable or the like is installed side by side with a trunk coaxial cable.
