How to seal the shielding at the entrance of EPS cable?

The cable entry point of an EPS cabinet is a weak point in the shielding and must be effectively shielded and sealed. The sealing method depends on the cable type and quantity:

1. Single/small number of shielded cables: Use an EMCCable Gland. The cable shielding layer makes 360-degree contact with the metal components inside the gland. The gland is threaded and pressed tightly against the cabinet panel, and equipped with a rubber sealing ring to achieve environmental sealing.

2. Multiple or mixed cables: Use a shielded busbar or filter board. Cables enter through the filter connectors on the board, which is tightly installed against the cabinet wall. A conductive gasket is used to seal the gap between the board and the cabinet.

3. Through-hole plate/metal conduit: For pre-fabricated cable harnesses, metal conduits can be used. The cable harness passes through the conduit, and both ends of the conduit are welded or crimped to the cabinet and the cable harness shielding layer. Gaps are filled with conductive epoxy resin or similar materials.

The core principle is to maintain the continuity of the shielding layer and achieve environmental sealing, while also ensuring low impedance grounding connections.
