Copper-Aluminum Connecting Clamp. Terminal connector with Copper-Aluminum Transition for Transformer Terminals

JTL-001-6

Product Features

1. Bi-Material Composite

Manufactured using copper-aluminum composite material, combining copper's superior conductivity with aluminum's cost-effectiveness and lightweight advantages.

2. Optimized Structural Design

Features a semi-circular arc structure at the conductor connection point to ensure maximum surface contact and secure clamping, preventing conductor creep.

Available in multiple configurations (0°, 30°, etc.) to accommodate different angles between the downlead and equipment terminal.

3. Advanced Manufacturing Process

Produced through precision stamping for single-step forming, requiring no additional post-processing. Ensures consistent product quality and reliable performance.

Product Advantages

1. Excellent Electrical Performance

Low contact resistance and high conductivity minimize power loss and heat generation.

Ensures stable current transmission with reliable, long-term connections.

2. Superior Corrosion Resistance

Optional tin-plated surface treatment enhances resistance to oxidation, ideal for harsh environments (coastal, industrial, or polluted areas).

Extended service life with durable material composition.

3. Quick and Easy Installation

Bolt-fastened design: Simply place the bare conductor in the semi-circular groove and tighten the bolt.

Self-aligning feature automatically centers the conductor for precise positioning.

Simplified operation with no loose parts, reducing installation time and errors.

Functional Features

1. Electrical Connection Functionality

Primarily designed for connecting busbar downleads to electrical equipment terminals (transformers, circuit breakers, current transformers, disconnect switches, etc.)

Ensures reliable electrical connection between copper and aluminum conductors

Facilitates uninterrupted current flow in power transmission systems.

2. Mechanical Fixation Capability

Provides robust mechanical support for conductors

Securely fastens conductors to electrical equipment

Withstands mechanical stresses including conductor tension

Maintains stable line connections under various operational conditions.Alternative technical expressions

For electrical connection: "Establishes low-resistance interface between dissimilar conductors"

For mechanical fixation: "Engineered to withstand dynamic loads and vibration
