How to Use Insulated Copper Braid with Self Amalgamating Tape for Secure Connections

Creating secure, long-lasting electrical connections is crucial to ensure safety, prevent failures, and maintain system integrity—especially in high-voltage or industrial environments. Two of the most trusted materials in this field are Insulated Copper Braid and Self Amalgamating Tape. When used together correctly, they offer unmatched performance in grounding, bonding, shielding, and insulating applications.

In this article, we’ll walk you through how to use insulated copper braid with self amalgamating tape to make robust, secure, and weatherproof connections.

🔧 Tools & Materials You’ll Need

• Insulated Copper Braid (with appropriate length and cross-section)

• Self Amalgamating Tape

• Wire cutters/strippers

• Crimping tool or soldering iron

• Terminal lugs (optional)

• Heat gun (optional for added sealing)

🧠 Step-by-Step Guide to Secure Connections

Step 1: Prepare the Copper Braid

Cut the insulated copper braid to the required length. Ensure it’s long enough to create a strong connection without putting stress on the wire.

✅ Tip: Use pre-insulated copper braids for added protection against short circuits and wear.

Step 2: Strip the Insulation (If Required)

If only part of the braid needs to be exposed (e.g., for grounding), strip off the outer insulation carefully using a knife or stripper. Avoid damaging the copper strands underneath.

Step 3: Terminate the Ends

Terminate the exposed copper braid by either:

• Crimping it into a lug, or

• Soldering it directly to a terminal or component

Make sure the connection is tight and electrically conductive.

Step 4: Wrap with Self Amalgamating Tape

Once the braid is secured in place:

1. Start wrapping the self amalgamating tape slightly before the exposed copper.

2. Stretch the tape as you wrap—it needs to be under tension to activate its self-fusing property.

3. Overlap each layer by 50% as you go along the length of the joint.

4. Cover all exposed copper and at least 1 inch of the insulated braid on both sides for a weatherproof seal.

✅ Pro Tip: Finish with a clean final wrap and press down firmly. The tape will bond to itself and form a strong, rubber-like seal within minutes.

Step 5: Optional Sealing with Heat

For outdoor or high-moisture environments, apply gentle heat using a heat gun to enhance the seal and conform the tape snugly to the cable shape. This is especially useful when combining with heat shrink sleeves or insulation tubing.

⚡ Why This Combination Works
