Figure parts A–D show steps in forming a "short tie" Western Union splice. Figure parts E and F show two possible "long tie" variations. [2]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.
Lineworker. A lineworker (also called a lineman or powerline worker) constructs and maintains the electric transmission and distribution facilities that deliver electrical energy to industrial, commercial, and residential establishments. A lineworker installs, services, and emergency repairs electrical lines in the case of lightning, wind, ice ...
Typical uses. Lineman's pliers are used in the electrical trade to cut, straighten, and bend wire, and also to twist wires together when making splices. Lineman's can be used to strip wire and some types of cable, although wire strippers are more commonly used for this purpose as they can strip wire more quickly without damaging the conductors ...
Electric power transmission, the tools and means of moving electricity far from where it is generated, date back to the late 19th century. They include the movement of electricity in bulk (formally called " transmission ") and the delivery of electricity to individual customers (" distribution "). In the beginning, the two terms were used ...
Live-line working. In electrical engineering, live-line working, also known as hotline maintenance, is the maintenance of electrical equipment, often operating at high voltage, while the equipment is energised. Although this is more hazardous for personnel than working on electrical equipment with the power off, live-line maintenance techniques ...
The International Brotherhood of Electrical Workers (IBEW) is a labor union that represents approximately 820,000 workers and retirees [1] in the electrical industry in the United States, Canada, [3] Guam, [4] [5] Panama, [6] Puerto Rico, [7] and the US Virgin Islands; [7] in particular electricians, or inside wiremen, in the construction industry and lineworkers and other employees of public ...
Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.
The National Joint Apprenticeship and Training Committee (NJATC) is the former name for the Electrical Training Alliance, a nonprofit organization created in 1941 by the International Brotherhood of Electrical Workers (IBEW) and the National Electrical Contractors Association (NECA). The NJATC helped developing and standardizing education in ...
