THREE-ROW INTEGRATED LAYING METHOD FOR SINGLE-CORE CABLE

摘要

PROBLEM TO BE SOLVED: To provide a three-row integrated laying method for a single-core cable, for laying work with almost no deflection at the middle portion of the cable even when a curved portion exists in a conveying and laying route.

SOLUTION: This three-row integrated laying method for the single-core cables accumulates the three rows of single-core cables in a triangular shape and delivers them with a plurality of motor rollers. The motor rollers includes common motor rollers 3 for conveying the accumulated three rows of cables and inside motor rollers 2 for conveying only an inner phase C among the lower two phases of the accumulated three rows of cables. The driving speed of the inside motor rollers 2 is made larger than the driving speed of the common motor rollers 3. A conveyance force of the inner phase C is made larger by the inside motor rollers 2, thus reducing mutual frictional force between the cables caused by a difference between angular speeds of the inner and outer phases C, B by the conveyance force.
