Study Notes
Joint Types and Applications
- The Western Union Short-tie Splice is commonly used to join two or more conductors inside a junction box.
Wire Splicing Methods
- The Western Union Long-tie Splice is extensively used in aerial wiring.
- The Y-splice method is suitable for small cables because the strands are flexible and can be wrapped in one operation.
Joint Characteristics
- The Duplex Cross Joint consists of two Cross Joint splices.
- The Knotted top joint is distinguished by its knot-like structure.
- The Wrapped Tap or Tee Joint is characterized by its wrapped tap or tee configuration.
Joint Usage Scenarios
- The Western Union Short-tie Splice is typically used for permanent connections.
- The Aerial tap joint is used for temporary taps on aerial wires.
- A Rat Tail or Pig Tail joint is used when a temporary tap is needed on a wire.
- The Knotted top joint is chosen over other types of joints when a more secure connection is required.
- The Duplex Cross Joint is used when a stronger connection is needed compared to a Cross Joint splice.
