Connecting Clamp (Brazed Cu-Al Terminal connector,Transition Clamp ,Transformer Terminals)

JTLQ-001-7

Product Features

1. Reliable Connection Performance

The brazing process enables a reliable connection between copper and aluminum with high bonding strength, meeting the mechanical and electrical performance requirements of electrical equipment.

2. Minimal Thermal Impact

The brazing process causes relatively little thermal impact on the base materials, avoiding performance degradation of copper and aluminum due to overheating.

3. Reasonable Structural Design

It typically adopts a structure with a copper layer clad on the surface of an integral aluminum substrate. Compared with clamps manufactured by some other processes, it has a more reasonable structure and a larger conductive area.

Product Advantages

1. Reduced Contact Resistance

Brazed joints exhibit good electrical and thermal conductivity, effectively reducing contact resistance, minimizing power loss and heat generation, and helping improve power transmission efficiency.

2. High Mechanical Strength

Formed by forging extruded aluminum rods, the clamp has a dense texture and high strength, avoiding internal porosity, sand holes, slag inclusions and other defects caused by casting processes. This reduces the risk of accidents such as crimping cracks and poor contact.

3. Strong Corrosion Resistance

The brazed layer between copper and aluminum can isolate air and moisture to a certain extent, reducing the electrochemical corrosion caused by copper-aluminum contact. Additionally, the copper surface of some clamps may undergo anti-corrosion treatments such as tin plating, making them more suitable for various harsh environments.

4. Cost Advantage

Compared with some other connection processes (such as friction welding), brazing-type copper-aluminum bushing clamps may have a greater cost advantage, with relatively lower prices and high cost performance.

Functional Features

1. Copper-Aluminum Transition Connection

Primarily used for connecting copper and aluminum power lines, such as joining copper conductors with aluminum conductors or achieving transition connections between copper busbars and aluminum overhead conductors. It is widely applied in power grids of various voltage levels, including overhead lines and underground cable systems.

2. Stable Electrical Connection

Suitable for permanent connections, it maintains long-term stable electrical connections to ensure the reliable operation of power systems and provides a stable current transmission path between electrical equipment.

3. Compatibility with Multiple Conductors

Capable of accommodating conventional conductors as well as other conductors within the diameter range of equipment clamps, it meets the connection requirements of conductors of different specifications and offers strong versatility.
