Grooving systems for multilayer spooling can be carved onto steel shells that are mounted onto old drums, by either bolting or welding, as an outer sleeve. Called split sleeves, they can be retrofitted onto old drums or mounted on new drums to allow a future change of application.
A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. [1] Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables [ 2 ] and wire products.
