What type of connectors are typically used for splicing stranded conductors?

The use of compression connectors for splicing stranded conductors is favored because they are designed to create a strong, reliable electrical connection through mechanical compression. When a compression connector is applied, it grips the conductors tightly as a result of the crimping process, ensuring minimal resistance and good electrical conductivity. This is critical in electrical applications, where the integrity of the connection can impact performance and safety.

Compression connectors are also well-suited for the physical structure of stranded conductors, which consist of multiple smaller wires. The design of compression connectors accommodates the flexibility of these strands, allowing them to maintain effective contact with the connector surface without the risk of loosening over time, which is particularly beneficial in environments subject to movement, vibration, or thermal expansion.

In contrast, welded connectors require high temperatures and are typically used in specialized applications. Twisted connectors, while sometimes used informally for quick connections or temporary setups, do not provide the same level of security and reliability as compression connectors. Soldered connectors, although they can provide good conductivity, are labor-intensive and can introduce additional points of failure if not executed properly. Thus, compression connectors emerge as the optimal choice for securely splicing stranded conductors in a variety of electrical contexts.
