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.
Downhole motor
For combined oil, water, pressure and temperature exposure.
Transformer and inductor
Conductor and insulation defined around winding radius, fill and hipot.
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.

Standard construction
Breakdown-voltage testing is based on the AWG 2801 construction; other conductor sizes and winding processes require validation.
Technical referenceValues are confirmed against category, gauge, length and termination
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.
