What feature is contained in compression sleeves for ACSR conductors?

Compression sleeves for ACSR (Aluminum Conductors Steel Reinforced) conductors are designed with an internal gripping unit. This feature is crucial for ensuring a secure and reliable connection between the conductor and its fittings. The internal gripping unit works by deforming when the sleeve is compressed, thereby tightly gripping the individual strands of the ACSR conductor. This mechanism is essential for maintaining electrical continuity and mechanical strength under load.

Understanding how the internal gripping unit functions helps linemen appreciate its role in preventing slippage and ensuring the integrity of the connection, especially in overhead power lines subject to tension and environmental conditions.
