摘要：The invention relates to a system of stretching overhead electric lines, more

particularly high-tension lines, according to which a pilot cord or haulage cable is

positioned in conventional manner over a set of top pulleys positioned at the highest

point on each pylon in the line, and is then used to pull a first haulage cable or guard

cable together with at least one other supplementary haulage cable, and/or

supplementary guard cable. Each supplementary cable, after passing the top pulleys on

which the first haulage cable of guard cable have been laid, is slid and guided downwards

until it rests on pulleys underneath. in this manner, each further haulage cable is already

positioned for drawing a conductor or bunch of conductors and other haulage cables if

required. In the aforementioned system, it is no longer necessary to position a pilot cord

for each conductor or bunch of conductors to be tensioned, but it is sufficient to position

a single pilot cord on the top pulleys of the pylons, since all the conductors or bundles

of conductors and/or further haulage cables are subsequently positioned automatically,

starting from the pilot cord or first haulage cable, during the subsequent stage of

tensioning.
