Build your own Insulation
Insulation is used to prevent shocks like plastics, polymers, bakelite, phenolic products. In power distribution ceramics, oil, glass and fiberglass is used. In telecommunications and electronics we use glass epoxy, teflon, silicones for isolating/separating conducting paths of copper and copper wires.Insulation Resistance Measurement, Polarization Index and High Voltage Breakdown tests measure effectiveness and quality.
I had a set of Victoreen Resistors which were in thin sealed
glass bulbs, like large reed relays from 1G Ohm to 1T ohm.
High Resistance measurement is possible from test voltages of
100V to 1000V. The leakage current can provide data for
evaluating resistance. In components like transformers, it
will take a long time for a stable reading, so the charge,
discharge, leakage of the Coil Capacitance can help measure
Insulation Resistance or polarization index.
Glass is perhaps one of the best insulators along with ceramic, teflon and the Silicones. These insulators are also excellent performers in high temperature. Glass fibers can be woven into cloth or braid for sleeves and separators. Glass cloth and has chemical and wear resistance. Alumina Ceramics are also heat conductors with excellent electrical insulation.Glass At High Temperature
