Title:
PIPE CABLE FOR AIR PRESSURE FEEDING AND AIR PRESSURE FEEDING METHOD FOR OPTICAL CABLE
Document Type and Number:
Japanese Patent JP2004246173
Kind Code:
A
Abstract:
To provide a pipe cable for air pressure feeding which improves the insertability of an optical cable into pipes for an air pressure feeding in the cable.
The pipe cable 100 for air pressure feeding having a plurality of the pipes 120 for air pressure feeding is inverted in a collection direction of the pipes 120 for air pressure feeding at specified intervals and therefore the pipe cable with which the smooth insertion of the optical cable is possible can be obtained. Also, a pressure-feedable distance can be made longer and further the line speed during the pressure-feeding can be improved. Further, the improvement in leading workability in midway of the pipe cable is possible as well.
