Servo - Resolver Cables

I'm having problems finding replacement cables for a servo resolver - Kollmorgen to be exact. The motor power cables are no problem - VFD cables with a UL TC-ER rating, 600V, Oil resistant I/II, flexing application. The resolver however requires a 20awg (or smaller), twisted pair, individual shield w/overall shield. I can't find a standard cable with TC-ER Oil I/II rating with 300v insulation (the system voltage is 230). Anyone know of a non-custom cable that fits this description? Thanks

Have you tried Helukabel ?

Thanks GlenD - they seem to have a wide selection - not sure if I can get by without the individual pairs not being shielded for the resolver feedback. Typically it should work but I'm still waiting for Kollmorgan to say so.
