The second high voltage cable run in the tractive system.
Same specification and rationale as HV Cable (1).
No part-specific design process is documented. The Tractive System subsystem design process applies: 1. Select the motor against the available options. EMRAX is effectively the only viable choice for a non-in-hub design; the 228 LV+43% keeps the 111 kW peak power of the 228 MV at a lower maximum operating voltage. 2. Select the controller against the motor. The PM100DX was chosen first, then discontinued; the recommended CM200DX was lighter and more powerful, but Cascadia does not support the EMRAX custom windings, which is what moved the team to the DTI HV-550 (30-800 VDC, 280 A max input, 320 kW max output, 95% efficiency, 6.8 kg). 3. Draw the tractive system diagram and the interlock chain, then place every component against it. 4. Choose cable and insulation for routing as well as rating. CoreFlex HV cable was chosen because it is far more flexible than standard HV wire, making routing inside the accumulator easier and cleaner, with thick insulation that helps at scrutineering. Nomex YT510 was chosen for safety barriers inside the container. 5. Bench test the shutdown chain before the pack is live.
