What is the purpose of a compression sleeve connector in electrical systems?

• A. To connect two conductors at lower voltages
• B. To insulate wires from moisture
• C. To facilitate splices in cables operating at voltages higher than 5kV
• D. To protect cables from physical damage

Answer: (C)

A compression sleeve connector is specifically designed to allow for secure and reliable splicing in electrical systems, particularly for cables that operate at voltages higher than 5kV. This type of connector uses a metal sleeve that compresses around the conductors being joined, ensuring a tight and low-resistance connection which is crucial for maintaining circuit integrity at higher voltage levels.

The application of a compression sleeve connector in high-voltage scenarios is critical to prevent failures that could lead to safety hazards or system outages. Compressing the sleeve not only provides a robust mechanical bond but also helps in maintaining conductivity while minimizing the risk of arcing, which can occur if the connection is not properly secured.

In contrast, connecting two conductors at lower voltages typically does not require the heavy-duty attributes of a compression sleeve connector, and insulation from moisture is achieved through different materials or methods, rather than through this type of connector. Additionally, while protecting cables from physical damage is important, it is not the primary function of a compression sleeve connector, as they are focused on ensuring reliable electrical splicing.
