Product Advantages and Applications
Advantages
- Completely Eliminates Copper-Aluminum Electrochemical Corrosion
Utilizes friction welding, flash welding, or brazing to achieve a molecular-level metallurgical bond between copper and aluminum, eliminating galvanic corrosion caused by direct contact between the two metals and significantly extending the joint’s service life.
- Excellent Electrical Performance
Low contact resistance (≤10 μΩ), minimal temperature rise, high current-carrying capacity, and low energy loss, meeting the IEC 61238 standard.
- Reliable Mechanical Connection
A bolt-tightening and arc-clamping structure ensures a secure grip, preventing conductor creep and loosening, and providing excellent resistance to vibration and wind sway.
- Flexible and Convenient Installation
Bolt-fastened design facilitates on-site installation, maintenance, and replacement, and accommodates various installation angles (0°, 30°, 45°, 90°).
- High-Quality Materials, Corrosion-Resistant and Durable
The copper end is made of red copper, while the aluminum end is made of high-strength aluminum alloy. The entire unit is hot-dip galvanized, providing oxidation and corrosion resistance, making it suitable for long-term outdoor and substation operation.
- High Versatility
Compatible with aluminum stranded wire, steel-core aluminum stranded wire, and copper equipment terminals, covering applications from power distribution to high-voltage transmission.
Typical Applications
- Connecting substation busbar drop-outs to copper output terminals on transformers, circuit breakers, isolating switches, current transformers, and wall bushings.
- Transition connections between copper and aluminum conductors in power distribution lines, and splicing of equipment leads to overhead lines.
- Copper-to-aluminum transition connections between electrical equipment and busbars in power plants, substations, and switching stations.
- Suitable for power transmission and distribution systems with voltage ratings ranging from 10 kV to 500 kV.

FAQ
Q: Why can't copper and aluminum be directly connected? Why must transition clamps be used?
A: Direct copper-aluminum contact produces electrochemical corrosion, forming oxide films that increase contact resistance and cause overheating. In severe cases, this can burn and break conductors. Transition clamps use special welding processes to block electrochemical corrosion.
Q: What is the difference between friction-welded and brazed transition clamps?
A: Friction welding offers high bonding strength, suitable for high-current applications with higher cost. Brazing has simpler process and lower cost, suitable for small-to-medium current applications. Both meet electrical performance requirements.
Q: Can copper-aluminum transition clamps be used for tension connections?
A: Generally not recommended for tension connections; mainly used for electrical connections with small mechanical loads. Tension connections should use specialized copper-aluminum transition tension clamps.
Q: What should be done if the transition clamp overheats during operation?
A: Check whether contact surfaces are oxidized or loose, verify tightening torque is sufficient, and check whether selection matches current capacity. Severe overheating requires de-energized replacement.
Q: Can transition clamps with cracks in the copper-aluminum bonding surface still be used?
A: Absolutely prohibited. Cracks in the copper-aluminum bonding surface cause contact resistance to increase dramatically, potentially causing serious accidents. Must be replaced immediately.
Q: How to determine when a transition clamp has reached end of service life?
A: Check for delamination or cracks in copper-aluminum bonding surface, measure whether contact resistance exceeds standards, and check for abnormal temperature rise. Preventive replacement is recommended when design life is reached.
