Aluminum Compression Splice
An aluminum compression splice is a precision-engineered conductor connector used in overhead power line construction to permanently join two aluminum conductors end-to-end. It is installed using hydraulic compression tools to create a high-integrity, low-resistance electrical and mechanical bond. Designed for transmission and distribution networks, it ensures continuous current flow while maintaining structural strength under mechanical loads, vibration, and environmental stress.
Manufactured from high-conductivity aluminum alloy, the splice is optimized for compatibility with AAC, AAAC, and ACSR conductors, depending on design specification. Its compression-based installation eliminates the need for bolted joints, reducing maintenance requirements and minimizing long-term contact resistance issues.
