Abstract
A hauling cord (L) for pulling an electric power line or the like cable into a conduit has an elongate linear body (,) that is typically a monofilament of a thermoplastic resin. The cord is of a regular or irregular cross section with one or more helical ridges (,) that extend around, along and integral with the linear body between opposite ends of the linear body. The helical ridges are formed by drawing and twisting a raw material of the linear body, and may have either of or both the opposite ends made thinner and/or twisted stronger than the remaining portion so that the pitch between the adjacent ridges is reduced. The cross section renders the cord lighter in weight and more slender, and nevertheless its compression strength and tensile strength are improved.
