Description

pay-off rack

technical field

The invention relates to the field of tools for electric power engineering, in particular to a pay-off rack.

Background technique

During the construction of the substation project, many problems were found in the laying out of cables. If you use the traditional method of unwinding, you need to lay the cable reel flat on the ground and let it out around the reel. The released cable will be twisted. If the sheath is damaged, the cable is prone to dead bends, which seriously affects the service life of the cable. The twisted cables are laid on the cable support, which is difficult to straighten out and smooth, and will also cause unsightly construction techniques. When the pay-off length is long, the error of cable length caused by pay-off twisting will increase, which will cause a waste of resources, and special personnel must be set up at each corner of the cable trench to take care of it, which wastes manpower.
