The most common types of splices for overhead conductors are compression splices and bolted splices.

• Compression Splices: These are the most widely used for high-voltage transmission and distribution lines. They are installed using specialized hydraulic crimping tools that compress the splice barrel onto the conductor. The compression process creates a robust, permanent mechanical and electrical bond that is highly resistant to vibration, tension, and corrosion. Our hydraulic crimping tools and tension stringing equipment are essential for this type of installation.

• Bolted Splices: Also known as mechanical splices, these use bolts and clamps to secure the conductor ends. While they are often used for temporary repairs or in applications where the tension is not a primary concern, they are generally less reliable for high-stress applications compared to compression splices. They are also prone to loosening and corrosion over time, which can lead to high-resistance connections and overheating.

The choice of splice is critical and depends on the conductor material, line voltage, and environmental conditions to ensure long-term reliability and safety.
