Single Tongue Compression Deadend

A compression deadend is a mechanical termination fitting designed to anchor and electrically secure overhead conductors at the end of a transmission or distribution line span. It is widely used in medium- and high-voltage power line construction to transfer tensile loads from the conductor to the supporting structure while maintaining optimal electrical continuity and long-term mechanical integrity.

Manufactured from high-conductivity aluminum alloy or aluminum-steel combinations, compression deadends are installed using a controlled hydraulic crimping process. This compression method creates a permanent, high-strength bond between the fitting and conductor strands, ensuring minimal electrical resistance and maximum pull-out strength under dynamic loading conditions.

Key Features

• High Tensile Strength: Engineered to withstand full-rated conductor tension and extreme mechanical loads.
• Low Electrical Resistance: Precision compression design ensures stable current transfer and reduced line losses.
• Corrosion-Resistant Materials: Aluminum alloy construction provides durability in harsh environmental conditions.
• Secure Hydraulic Crimping: Multiple compression zones for uniform load distribution and enhanced grip.
• Compatibility: Suitable for AAC, AAAC, ACSR, and other overhead conductors.
• Vibration Performance: Designed to resist conductor creep and fatigue under wind-induced oscillation.
• Standards Compliance: Manufactured in accordance with applicable ASTM and IEC specifications.
