CW-LWC: Large (4/0- 2/0) Wedge Clamp Non-Irridite

Product Name:​ CW-LWC Large Aluminum Service Wedge Clamp (Non-Iridited)

Model:​ CW-LWC

Type:​ Large (4/0 - 2/0)

Finish:​ Non-Iridited (Mill Finish Aluminum)

1. Product Overview

The CW-LWC Aluminum Service Wedge Clamp is a robust, single-piece solution designed for the efficient dead-ending of self-supporting service drop wires. Engineered for utility linemen and contractors, this clamp provides a secure, reliable termination for aluminum conductors without the need for complex tools or pre-forming. Its design allows for quick installation at any point along the span, making it ideal for both new construction and maintenance applications.

This model is specifically configured for use with larger gauge conductors (Class 4/0 to 2/0) and features a non-iridited aluminum body, which offers excellent conductivity and weight savings while maintaining structural integrity.

2. Key Features & Advantages

• Versatile Conductor Compatibility:​ Designed to grip a range of conductors including ACSR (Aluminum Conductor Steel Reinforced), AAAC (All Aluminum Alloy Conductor), and solid/stranded aluminum conductors within the 4/0 to 2/0 size range.

• Flexible Installation:​ Can be installed on the bare neutral messenger at any pointin the span, providing maximum flexibility for field adjustments and repairs.

• Material Integrity:

  • Body:​ High-strength Aluminum Alloy for superior corrosion resistance and lightweight handling.

  • Bail Wire:​ Stainless Steel bale wire ensures durability and prevents rusting at the attachment point.

• Sag Adjustment:​ Allows for easy, on-the-fly adjustments to drop wire sag, ensuring proper tension and clearance according to electrical codes.

• Material Efficiency:​ Enables precise cutting of the drop wire to the exact required length, eliminating waste and reducing inventory complexity.

• Reliable Performance:​ Provides a permanent, low-resistance connection suitable for low-tension dead-ending applications.

3. Technical Specifications

4. Application Description

The CW-LWC clamp is primarily used in overhead distribution systems to terminate the "service drop"—the cable running from the utility pole to a customer's building. By gripping the insulated conductors and securing them to the bare neutral messenger wire, it creates a stable and safe endpoint for the service line. The wedge design ensures that as tension is applied, the grip on the conductor tightens, preventing slippage under load or environmental stress (e.g., wind, ice).

5. Ordering Information

• Standard Packaging:​ 50 pcs / carton

• Shipping Weight:​ 17 kg / carton​ (or 37.5 lbs)

Note:​ This product is supplied in a non-iridited (mill finish) state. While offering good corrosion resistance for most environments, an iridited (yellow chromate) finish is recommended for highly corrosive coastal or industrial areas. Please consult your supplier for alternative finishes if required.

6. Installation Instructions

To ensure optimal performance and safety, please follow these steps during installation:

1. Preparation:​ Strip the insulation from the conductor end to the appropriate length (typically the length of the clamp body plus 1 inch) to expose the bare aluminum conductor. Ensure the conductor is free from damage, dirt, or oil.

2. Threading:​ Insert the prepared conductor through the stainless steel bail wire opening, then continue threading it through the wedge mechanism.

3. Positioning:​ Place the clamp onto the bare neutral messenger at the predetermined location within the span.

4. Tensioning:​ Pull firmly on the insulated portion of the drop wire to seat the wedge tightly against the conductor. Use appropriate pulling pliers or tensioning tools until the clamp is fully engaged and locked.

5. Inspection:​ Gently tug back on the conductor to confirm the clamp has a firm grip with no slippage. Ensure the stainless steel bail maintains good contact with the neutral messenger.

8. Frequently Asked Questions (FAQ)

Q1: What does "Non-Irridite" mean?

A:​ "Non-Irridite" refers to the natural aluminum oxide finish (Mill Finish). It means the product has not undergone chromate conversion coating (Iriditing). While it offers good corrosion resistance for general atmospheric conditions, we recommend using Iridited (yellow chromated) clamps for severe coastal or industrial environments to prevent galvanic corrosion.

Q2: Can this clamp be used with copper conductors?

A:​ No. This clamp is specifically designed for aluminum conductors (ACSR, AAAC, Aluminum). Using it with copper conductors is not recommended due to differences in hardness and the risk of severe galvanic corrosion. Please select a dedicated copper clamp or a bimetallic (Cu-Al) transition clamp for such applications.

Q3: What does the Ultimate Tensile Strength of 1,600 lbs imply?

A:​ This indicates the maximum static load the clamp can withstand before breaking. In practical applications, a safety factor of at least 2x is recommended. Therefore, this clamp is suitable for light-to-moderate tension scenarios commonly found in low-voltage distribution networks.
