Size matters little in identifying a good insulator, unless you mean material thickness. The breakdown strength of the insulating material affects how thick the material has to be in order to sustain a specific voltage difference without harm done to any one or thing. The breakdown strength is normally expressed as volts per unit length (aka thickness). I presume you can get the information from a science or engineering handbook or manufacturing datasheet. You need to over-design and allow extra thickness than what the paper says.

Why the graph of breakdown voltage is cheaper than knee voltage?
Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.
Creepage distance in insulators?
It is the shortest distance between the conductors measured along with the surface of insulators.
What is the name of two insulators?
Insulators in electricity can be glass or ceramic.Insulators in heating can be polystyrene or fibre panels.
What are signals composed of pulses of precise positive voltages and zero voltages?
Digital
If you have to add two alternating voltages how to add them?
A: Alternating voltages means the phase factor must be considered.
Why suspension insulators preferred for high voltage power transmission?
'Suspension' type insulators are less expensive to manufacture than 'pin' type insulators for voltages in excess of around 33 kV. Each 'dish' is designed for specific voltage (e.g. in the UK, typically 11 kV), and several can be added to form a 'string' to match any desired voltage level. This inceases their versatility. Suspension insulators also allow for greater lateral movement of the conductors.
Why can wire sizes be smaller when higher system voltages are used?
It has to with the fact that when voltages go higher the current goes lower. The lower the current a device draws, the smaller the wire size needs to be to carry that current.
Why do people collect glass insulators?
Glass insulators were used on telephone wires. Many are between 50 and 125 years old.Glass insulators have many unique shapes, sizes, and colors. Naturally, they would become collectables. Many people like them for their shapes and color. People also like to collect them for their rarity.
What do you call poor conductors?
Insulators.
What has the author E Kuffel written?
E. Kuffel has written: 'High-voltage engineering' -- subject(s): Breakdown (Electricity), Electric discharges through gases, Electric engineering, Electric insulators and insulation, High voltages
Need labeled diagram of a generator?
Generators come in many shapes, sizes and connections. You have to be more specific as to the voltages, kva, kw, or amperages, to get this question answered.
Are Crayons insulators or conductors?
insulators
Are humans conductors or insulators?
humans are not insulators, but are conductors!
What is the part of speech for insulators?
Insulators is a plural noun.
Why are blankets good insulators?
Blankets are defined to be insulators.
List of good insulators?
Some materials such as "silicon dioxide or teflon" are very good electrical insulators. A much larger class of materials, for example "rubber-like polymers and most plastics" are still "good enough" to insulate electrical wiring and cables even though they may have lower bulk resistivity. These materials can serve as practical and safe insulators for low to moderate voltages (hundreds, or even thousands, of volts)."
What is the population of NGK Insulators?
NGK Insulators's population is 3,272.
