20 kV High Voltage Wire

Tinned-copper stranded wire (7 strands approximately 0.04" total diameter), surrounded by flexible silicon insulation (0.135" OD). This wire is best for AC or DC high-voltage applications up to its rated value.

Price is per foot. Adjust "Quantity" to select how many feet you need.

Special Note: it is best to avoid running this HV wire across anything grounded (like a table, touching anything metal, across the ground, etc.), as high voltage is prone to parasitic voltage loss when near ground points. So if your device is not delivering the expected voltage, be sure the HV wire is suspended in the air, with longer runs supported by ceramic or plastic insulators if possible, or if this is not possible then place a strip of plastic (the thicker the better) beneath the HV wire where it would otherwise touch the ground, or pass the HV wire through polyethylene tubing which has good additional insulating properties (this can be found at hardware stores).
