[Boatanchors] multi conductor cable needed

[Paul Kraemer]

Anixter also has same type wire in 1kv insulation and others in much higher 
voltage but unless you have a grounded metal shell in close proximity to a 
wire the 600 v is adequate for many ham purposes because the breakdown 
between two 600v insulated wires is really total of 1200v.
Most rotor cable and general purpose control cable found laying about is 
probably  only 300v wire---at best.
If I ever had one hv lead I was really concerned about I'd just teflon 
sleeve it with sleeving from McMaster Carr
Also, just for fun, white pvc insulated can be color striped with permanent 
markers.  If you twist the wire with your vs drill then run the marker down 
the length it will look "store bought" when it relaxes from the twist

>>I make up what I need from stock wire I get from Anixter
>> PVC insulated 600v stranded and gauge / color as required.
>> I sleeve the wires in a piece of heat shrink tubing that is just large 
>> enough to house the wires  but do not shrink it.
>> If you twist the bundle of wires prior to sleeving them (one end clamped 
>> in vice, other end in vs drill to twist) you will have a very 
>> professional looking cable
>> A bit of talcum powder over the wire bundle makes pulling through sleeve 
>> a lot easier.
>> When I worked for AEC we made special cables up to 100 ft long that way. 
>> That's a two person job though.
