A western union splice is used to...

• A. join small solid conductors together
• B. connect coaxial cables
• C. join large power cables
• D. insulate splices

Answer: (A)

Connecting small solid conductors is what a Western Union splice is designed to do. By twisting two wires together for several turns, you create multiple points of contact along their surfaces, giving a low-resistance, mechanically stable joint that can then be secured with solder or insulation. This method works best with small solid conductors because they stay aligned and grip each other well in the twist, making a reliable connection without special tools. It’s not used for coaxial cables, since coax requires maintaining shielding and impedance; a Western Union splice would disrupt the shield and could impair signal integrity. It’s also not ideal for large power cables, which need larger connectors or lugs to handle high current safely and provide sturdy insulation. You’ll often insulate the splice after forming the connection, but the main purpose is to join the conductors while preserving electrical continuity.
