what would be the best a.c voltage insulation to stop arcing between two points of about 4mm,the insultors need to be in tubeular form of about 6mm inside diameter and about 14 mm out side diameter

Is that in or out of a vacuum be very clear.

RTV (silicon rubber) would work, or the high voltage putty that is used around high voltage circuits in a TV. Since you allow insulation to actually push the 2 point apart by 5 mm on each side, for a total separation of 10mm, would not simply separating the conductors by that amount do as much good? Think about it, you allow a tubular insulation of 6 mm ID and a 14 mm OD, but the distance between the conductors is 4 mm. If the electrodes are not movable, the insulation tube is not going to fit. Heat shrink tubing, which has been specified by another respondent, but that person used the chemical name rather than just giving it by it's common product name would work since this material has a high insulation value of about 600 volts per mm.

Insulators vary by there composition. The better the insulator the higher the voltage potential they can insulate. Standard wire usually protects against 600v. However, high voltage lines might need 15,000v protection. The higher the voltage they insulate the greater the cost. Therefore, one only insulates the voltage they need as cost becomes prohibitively expensive. A simple experiment would be to take a neon transformer with a variac so you can control the voltage from 0 to 9-12kv. You can place an insulator between the electrodes and see at what potential the insulation breaks down. Be careful, though, as these voltages are lethal.

What is the maximum temperature of ur equipment ?we can use 1) fiber glass type insulators or 2) fiber or 3)ceramic or 4)Teflon tube (pttf) or 5)Re chem sleeves for the particular diameter heat it & shrink it( normal temp.area )

More information is required to make a precise prediction, eg. temperature, voltage,environment. Ebonite is a very good insulator and can be turned on the lathe to fit.

Plastic knitting needles will work, you can cut them to the length you require and are cheap

We currently use PVC.
There are many ceramics that are better but not practical
