01 / CONFIGURATION DIRECTIONS
Select a configuration from the application boundaries
These configurations establish a practical discussion starting point. The final product requires a controlled specification based on interface, length, installation and validation conditions.
Shielded feeder assembly
Controls EMI and return path alongside high-voltage delivery.
Platform-specific feeder
Gauge, length, terminals and routing form a complete assembly.
Match a solution direction to the link target
Solution codes support early technical discussions by aligning protocol, construction, link boundaries and application in one view.

03 / TYPICAL CONSTRUCTION
From functional core to terminated interface
High-conductivity conductor
Gauge, stranding and plating are selected for resistance, flex and termination.
Primary insulation
Thin-wall high-temperature material establishes voltage, PD and abrasion margin.
Field or shield layer
Grading, shielding and return paths are added for high-voltage or EMI needs.
Mechanical protection
Tapes, braid or jacket improve cut-through, wear and installation durability.
Termination and strain relief
Crimp, solder, connector and thermal-cycle interfaces are controlled together.
