Area of application for Flat Braids

Tinned flat copper braids, from which earth braids are also manufactured, have a significantly lower impedance than comparable round ground cables and are therefore much better suited for establishing high-frequency grounding.

In addition, flat copper braids are exceptionally flexible, which means that the number of contact points can be reduced compared to solid connections. Furthermore, this flexibility allows for the compensation of construction tolerances during installation and can drastically reduce assembly time.

Establishing connections

Below you will find the recommended procedure for making connections with our Copper Sleeves:

1. Preparation of the material:

Cutting the flat copper braid to length: Cut the flat copper braid to the desired length. The cut must be clean and at a right angle in order to evenly cover all individual strands. Crushing or fraying should be avoided.
Stripping (not applicable): As these are uninsulated flat copper braids, stripping is not necessary. The strand is inserted directly into the sleeve.
Prepare the sleeve: Ensure that you have the appropriate sleeve (cross-section and shape) for your flat copper braid and that it is clean inside.

2. Inserting and positioning:

Inserting the flat fabric tape: Push the end of the flat strand completely into the PLC sleeve. It is essential that all individual strands are seated in the sleeve to the specified depth and do not protrude beyond it.
Selecting the tool: Only use professional crimping pliers or a hydraulic or electro-hydraulic press with the appropriate press inserts (dies).

3. The pressing process (crimping):

Applying the press insert: Place the pressing tool exactly in the center of the area of the sleeve that surrounds the end of the flat copper braids.
Pressing (crimping): Press the crimping pliers or press together with full force until the pressing process is complete.
Successful connection: This deforms the sleeve so that the many individual strands of the fabric tape are cold-welded and pressed into a solid, homogeneous mass without air pockets. This is crucial in order to minimize contact resistance and prevent overheating.

4. Quality control:

Appearance: The crimp must be even and must not show any cracks or extreme deformations. A slight bulge of the sleeve at the crimp edge is normal.
Tensile test: Pull firmly on the connection to ensure that the flat copper braids cannot be pulled out of the sleeve. The mechanical strength must be very high.
Contact reliability: After pressing, make sure that no individual copper wires of the strand are protruding and that the connection is cleanly finished.
