The choice of connection method for overhead line conductors is crucial for ensuring a safe and reliable power supply. The most common methods are:

1. Crimp Connection (Compression): This method involves inserting the conductor into a connector and then using a special hydraulic or mechanical tool to compress it. This creates a highly secure, low-resistance electrical and mechanical bond.

2. Mechanical Connection: These connectors, often called bolt-and-nut connectors or split-bolt connectors, use a bolt to clamp the conductors together. They are popular for their ease of installation without specialized crimping tools, but require precise torque to ensure a reliable connection.

3. Insulation Piercing Connectors (IPCs): A modern and highly efficient method, IPCs allow for a connection to be made without stripping the conductor’s insulation. The connector’s teeth pierce the insulation to make contact with the conductor, making installation faster and safer, especially for live-line work.
