CW-LFWC: Large (2- 6) Aluminum Wedge Clamp | Service Wedge Clamp

Product Name: CW-LFWC Series Aluminum Service Wedge Clamp

Type:​ Large Size (2-6) | Application: Overhead Service Drop / Dead-Ending

1. Product Overview

The CW-LFWC Aluminum Wedge Clamp​ is a robust, heavy-duty solution designed for the secure dead-ending of self-supporting service drop wires. Engineered for utility and electrical contractors, this clamp provides a reliable termination point when attaching drop cables to a bare neutral messenger at any position along the span. It is specifically constructed to handle low-tension applications involving ACSR (Aluminum Conductor Steel Reinforced), AAAC (All Aluminum Alloy Conductor), and solid aluminum conductors.

Its primary function is to securely anchor the conductor while maintaining the integrity of the cable’s insulation and core, ensuring a safe and stable connection from the pole to the building.

2. Key Features & Advantages

This section details the technical benefits and practical advantages of the CW-LFWC clamp:

• Versatile Conductor Compatibility:

  Designed to grip a wide range of conductors including ACSR, AAAC, and Aluminum. This eliminates the need for multiple specialized clamps, simplifying inventory management.

• Premium Material Construction:

  • Body:​ High-strength, corrosion-resistant aluminum alloy.

  • Wedge/Bail:​ Stainless steel bial wire mechanism ensures long-term durability and consistent gripping force without damaging the conductor.

• On-Span Installation Flexibility:

  Unlike some connectors that require access to specific points, the CW-LFWC can be attached to the bare neutral messenger at any point in the span, offering maximum flexibility during installation.

• Sag Adjustment Capability:

  The design allows for easy adjustments to the drop wire sag after installation. This ensures proper tensioning and a neat, professional appearance.

• Material Efficiency:

  Optimized design allows the drop wire to be cut to the exact required length, minimizing waste and reducing installation costs.

• Superior Corrosion Resistance:

  The aluminum body and stainless steel components provide excellent resistance to atmospheric corrosion, making it suitable for harsh weather conditions and prolonging the service life of the connection.

• Simplified Installation:

  The wedge mechanism allows for quick, tool-free installation, significantly reducing labor time and effort compared to traditional bolting methods.

3. Technical Description

The CW-LFWC operates using a powerful wedging action. When the bail wire is tightened, the internal wedge forces the conductor into a secure grip against the aluminum body. This creates a high-friction hold that resists slipping under tension. The large size variant (Size 2-6) is engineered to accommodate heavier gauge conductors commonly used in service drops.

4. Applications

• Residential and commercial service drops

• Dead-ending self-supporting aerial cables

• Overhead line construction and maintenance

• Connecting service wire to a span messenger

5. Summary

The CW-LFWC Aluminum Wedge Clamp combines mechanical strength with ease of use. Its durable, corrosion-resistant construction ensures a long-lasting connection, while its flexible design empowers installers to work efficiently in the field. It is the ideal choice for professionals seeking a reliable, cost-effective solution for terminating service drop conductors.
