Automatic Aluminum Splice for Overhead Line – Self-Acting Compression Connector

Automatic Aluminum Splices

Product Description：

The Automatic Aluminum Splice for Overhead Line is a self-gripping connector designed for tension splicing of AAC, AAAC, and ACSR conductors. Featuring an internal spring-catch mechanism, the splice automatically grips the conductor when inserted, eliminating the need for hydraulic compression tools. Its high-strength aluminum alloy body ensures secure electrical continuity, reliable mechanical performance, and rapid installation for both new construction and emergency line repair.

Product Advantages：

1. Tool-free automatic gripping, suitable for quick installation

2. High electrical conductivity with stable long-term performance

3. Spring-catch mechanism prevents conductor slippage

4. Corrosion-resistant aluminum alloy for outdoor environments

5. Ideal for emergency restoration and live-line work

6. Compatible with multiple conductor types (AAC/AAAC/ACSR)

Application Scenarios：

1. New Overhead Line Construction：During stringing operations, conductors from different reels are joined by inserting each end into the automatic splice until the internal spring mechanism locks them in place.

2. Emergency Line Repair and Restoration：Technicians use the splice to quickly reconnect broken conductors after storms or mechanical damage, restoring power without requiring compression tools.

3. Tension Splicing for ACSR, AAC, and AAAC Conductors：The splice withstands full-rated tension, allowing it to be used on transmission and distribution conductors without reducing mechanical strength

4. Live-Line Maintenance Work：Compatible with insulated tools, the splice allows joining or bypassing conductors under energized conditions, reducing outage durations.

5. Rural Electrification and Long-span Lines：Used to connect long-span conductors where fast installation and lightweight fittings are preferred.
   

Quality Assurance：

Widely used in overhead transmission and distribution lines, especially for mid-span conductor splicing and emergency repairs.Each splice undergoes tensile testing, electrical resistance testing, and dimensional inspection. The internal spring mechanism is tested for locking strength and long-term durability.
