When repairing braided shielding, how much should the heat shrink tubing overlap be?

The appropriate overlap of heat shrink tubing when repairing braided shielding is 1/4 inch. This specific overlap ensures that the tubing adequately covers the damaged area and creates a secure seal over the braided shielding. A 1/4 inch overlap strikes a balance between providing enough coverage to protect the connection while also preventing excess bulk that could lead to difficulties in fitting equipment or connectors closely together.

Using a smaller overlap might not adequately cover the entire damaged area, potentially risking exposure of the shielding underneath. Conversely, a larger overlap could lead to unnecessary thickness and stiffness, which might complicate the assembly or flexibility of the cable. Therefore, 1/4 inch is widely recognized as an optimal choice for effective repair and maintenance in braid shielded cables.
