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.
What else can I help you with?
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.
What are signals composed of pulses of precise positive voltages and zero voltages?
Digital
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.
If you have to add two alternating voltages how to add them?
A: Alternating voltages means the phase factor must be considered.
Why can glass insulators be used in electric pylons?
Glass insulators are used in electric pylons because they are good electrical insulators, preventing the electricity from flowing through the pylon structure to the ground. Glass is also durable and can withstand high voltages and harsh weather conditions. Additionally, glass insulators do not degrade over time like some other insulating materials.
What characteristics does insulator have?
Insulators are materials that do not conduct electricity well. They have high resistance to the flow of electrons, making them suitable for preventing the transfer of electrical current. Insulators also tend to have high dielectric strength, allowing them to withstand high voltages without breaking down.
Why can wire sizes be smaller when higher system voltages are used?
Using higher system voltages reduces the amount of current needed to transmit the same amount of power, allowing for smaller wire sizes to be used. Smaller wire sizes result in cost savings and reduced material requirements in the system. Additionally, smaller wire sizes can also lead to less voltage drop over longer distances.
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 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 has the author E Kuffel written?

Are Crayons insulators or conductors?
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 do you call poor conductors?
Poor conductors of electricity are often referred to as insulators. Insulators have high resistance to the flow of electricity due to their molecular structure, which makes them unable to conduct electricity efficiently. Examples of insulators include rubber, plastic, and glass.
Are humans conductors or insulators?
humans are not insulators, but are conductors!
What is the population of NGK Insulators?
NGK Insulators's population is 3,272.
