Here’s how: Hold the wires parallel to one another. It’s ideal for joining two wires that will be kept under tension. The individual splices are staggered to prevent a large bump when the cord is taped. Electricians started using the lineman’s splice, or Western Union splice, in the early 1900s. Figure 5-32 shows how solid wires are spliced. If the cord must be saved, use twist lock plugs and receptacles to rejoin the cord. they should be used for emergency purposes only.
Western union splice portable#
Portable Cord SplicesĬord splices are weak because there is no connector to hold them together therefore. Solid core wires can benefit from the use of this method, but stranded wires can also be utilized. They use an insulation displacement connection and they dont really crimp. In fact, Id say this is quite a bit less strong secure and reliable than a western union splice with heat shrink and tape. There’s no comparison between the Splice and Lineman. These things are silly to me because they are without question less reliable than a handy box with wire nut splices inside, buried in the wall. Alternatively, using a Western Union splice (a) may be able to get your wires together. Study figure 5-3 1 to determine the proper technique in making this splice. A twist and turn of an helix from a different direction is referred to as an inverted helix. This method can be used where the cable may be subject to loading stress. A certain amount of practice may be necessary to make this connection look neat. 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 connection is one of the most difficult to make. 5-31) is a type of splice that allows a connection to be made without cutting the main line. If the splice is to be taped, care should be taken to eliminate any sharp edges from the wire ends. this splice was used to repair telegraph wires. The most common splice is the Western Union splice that dates back to the time of telegraph. 5-30) is used when the connection must be strong enough to support long lengths of heavy, wire. Splicing electrical wiring is relatively simple. Twisting the wires together first ensures that all the wires are fastened together properly. When more than two wires are joined in a pigtail splice, as shown in figure 5-29, they should be twisted together securely before the solderless connector is putįigure 5-29.Multiple-wire pigtail splice. When a solderless connector is used instead of tape. the ends must be bent back so the sharp edges will not penetrate the tape (fig.
Western union splice how to#
The use of welding procedure specification is unimportant.Figure 5-28 shows how to make a pigtail splice. In the welding procedure specification, the process of cleaning the metal is unavailable. The flux will clean the copper and allow the solder to flow. until the splice is saturated with solder. Heat the wire and add the solder to the wire, not the iron. The electrode to be used in welding is not necessarily needed in the welding procedure specification. Then I would twist the two wires together in the Western Union splice, apply a heavy amount of soldering flux directly onto the wires (rubbing the flux into the wires), and soldering. The design of the metal to be joined is also seen in the welding procedure specification.
You can also see the pre and post welding heat treatment using the welding procedure specification. Welding procedure specifications do not include the current setting and polarity of the welding machine. Welding procedures specification contains specifications and grades, wall thickness, size, yield and metallurgical concerns of metal to be welded. Pipeline industries do not use welding procedure specifications. Welding procedure specification is needed because it is a requirement set by different welding codes. A method of tightly joining two ends of metal wire by twisting each around the other. Welding procedure specifications is a document that contains important variables in making quality weld product. Western Union splice (plural Western Union splices). Learning Task 1: FACT or BLUFF Directions: On a separate sheet of paper, write FACT if the sentence states true statement about welding procedure spec
