[Milsurplus] ARC-58 wire harness

[Francesco Ledda]

Yes you need to worry, since need to avoid voltages being coupled to the control wires. Since the unit is powered at 400Hz, opportunities for coupling is even bigger.

Finally getting around to making up the wire harness from the ARC-58 receiver/exciter to the control unit.  Found the connectors and wire on eBay for not much money so I have run out of excuses to put the task off.  1000 foot roll of white 22 AWG rubber insulated wire, 19 strands, 1kv rated for under $30 including shipping, what a deal!

 

I see from the cabling diagram that the frequency control lines between the receiver/exciter and control unit are shielded.  Checked my stash of wire and I only have shielded pair cable.  These lines only carry DC so if needed at all, is the wisdom of the group that shielded wire pairs are good enough?  I assume that shielded wires were specified for the noisy aircraft environment.  Since I will make the harness only 10 feet long, do I even need to worry about shielded wire?  The 115 vac 400 cycle modified square wave power will not be present in this harness.
