Method of joining electrical cable
Western Union splice
The Western Union splice or lineman splice is a method of joining electrical cable, developed in the nineteenth century during the introduction of the telegraph and named for the Western Union telegraph company. This method can be used where the cable may be subject to loading stress. The wrapping pattern design causes the join to tighten as the conductors pull against each other.
