There are many types of insulators:
1. Solid. Rubber: Early rubber was taken from rubber trees.
Latex of rubber grass and other plants.
After processing, it is made into a material that is elastic, insulating, impermeable to water and air.
Plastics: Plastics are excellent insulators, so they are susceptible to static electricity, and antistatic agents can give plastics light to moderate electrical conductivity, which can prevent the build-up of electrostatic charges on the product.
2. Liquid. Such as various natural mineral oils, edible oils, alcohol.
3. Gas. Carbon dioxide.
It can directly clean indoor and outdoor transformers, insulators, distribution cabinets, wires and cables with live load (below 37kv); Generators, motors, rotors, stators and other components are cleaned without damage. Oxygen, nitrogen, hydrogen.
Relationship with conductors.
Insulators and conductors are not absolute, and there is no insurmountable gulf between them.
The distinction between the two is mainly the amount of charge that can move freely internally, but it is also related to external conditions (e.g. voltage, temperature, etc.). An insulated object at room temperature is converted into a conductor when the temperature rises to a considerable degree, due to the increase in the number of charges that can move freely.

Insulator is a physical term, as opposed to conductor, which means that objects that do not conduct electricity, such as dry wood, cloth, etc., are insulators. Now society also extends him to a hyper-rational person who is not easily infected by external emotions, and is generally more common in business elites. ~

An insulator is a substance that is not good at conducting electric current or an object that does not easily conduct electricity, also known as a non-conductor. They have extremely high resistivity and are a material that hinders the flow of electric charge. Common insulators in life are:
Plastic, rubber, ceramic, etc. Insulators and conductors are not absolute and can be converted under certain conditions.

An insulating material is a dielectric. In layman's terms, an insulating material is a material that can prevent the passage of electric current through it, that is, a non-conductive material. Commonly used insulating materials are: gas, plastic, wood, etc.
Liquids: such as transformer oil, cable oil, capacitor oil, etc.;
Solid materials: including two categories, one is inorganic insulating materials, such as mica, asbestos, electric porcelain, glass, etc.
The other category is organic substances, such as synthetic insulating paper, plastics, etc.
Boding insulation, the insulation material is customized.

[Common insulators in life].Plastics, rubber, glass, ceramics, various natural mineral oils, silicone oils, trichlorobiphenyls, air, carbon dioxide.
[Classification of insulators].1) External insulation. That is, the part of the insulating structure with the atmosphere as the insulating medium, and its electrical strength is determined by the breakdown strength of the gap in the atmosphere or by the flashover strength along the solid insulating surface in the atmosphere.
2) Internal insulation. The part of the insulating structure that does not directly use the atmosphere as the insulating medium, but uses oil, compressed air, vacuum, SF6, etc. as the insulating medium.

Common insulators are:
1. Ceramic: used as an insulator on high and low voltage transmission lines in the power industry. bushings for motors, pillar insulators, insulators for low-voltage electrical appliances and lighting, as well as insulators for telecommunications, insulators for radio, etc.;
2. Carbon dioxide: hail roller can directly clean indoor and outdoor transformers, insulators, distribution cabinets, wires and cables with live load (below 37kv); Generators, motors, rotors, stators and other components are cleaned without damage.
3. Glass: Glass is an amorphous inorganic non-metallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added.
4. Rubber: The early rubber was latex taken from rubber trees, rubber grass and other plants, and was processed into materials with elasticity, insulation, impermeability to water and air.
5. Plastic: Plastic is an excellent insulator, so it is easy to carry static electricity, and antistatic agents can give plastic light to moderate electrical conductivity, which can prevent the accumulation of electrostatic charge on the product.

The second category is liquidsSuch as various natural mineral oils, silicone oils, trichlorobiphenyls, etc.;
The third category is gas bridgesSuch as air, carbon dioxide, sulfur hexafluoride, etc.;
In life, glass rods, glasses, plastic rulers, erasers, wooden blocks, knife handles, edible oil, etc. are all common insulators.

Substances that are not good at conducting electric current are called insulators, and insulators are also called dielectrics.
Insulators and conductors, there are no absolute boundaries. Insulators can be converted into conductors under certain conditions. Note here:
The reason for conducting electricity: Whether it is a solid or a liquid, if there are electrons or ions inside it that can move freely, then it can conduct electricity. There is no free-moving charge, and under certain conditions, conductive particles can be produced, then it can also become a conductor.
Uses:
Insulators are usually used as the outer cladding of cables. In fact, air is an insulator in its own right, and no other substances are needed to insulate it. High-voltage power lines are insulated by air, as it is not practical to use solid (e.g. plastic) cladding.
However, wires touching each other can cause short circuits and fires. In coaxial cables, the conductor in the center must be in the center to prevent the reflection of electromagnetic waves.
In addition, any voltage above 60V can cause a risk of electric shock or electric shock to the human body. The use of insulators as exterior cladding can prevent these problems.
In electronic systems, printed circuit boards are typically made of epoxy plastic and fiberglass, and a non-conductive substrate supports the copper wire layer. In electronic devices, tiny and delicate active parts are embedded in non-conductive epoxy, phenolic, glass or ceramic coatings.

What is Insulator?
It is an object that does not conduct electricity, such as wood, plastic, glass, rubber, etc.
What are the common insulators?
Insulation is a relative concept, the same paper, can break down into a conductor under high pressure, but it is indeed an insulator at low voltage, and it becomes a conductor if it encounters water. Common insulators are ceramics, rubber, dry cloth, dry wood, plastic products, air, pure water, glass, processed insulating oil, bakelite, mica, and polyvinyl chloride.
What is Insulator?
Definition of insulator: An object that does not easily conduct electricity is called an insulator. This is the physical definition of modern people who say that they can't get over electricity for others, that is, they don't have a feeling of liking, people who are not easy to like others, who have no feeling for something or something, and are not interested.
Rejecting all objects of fate, to put it seriously, not interested in the opposite sex, I feel that basically men and women are the same, there is no difference. Or rather, a tactful way of refusing
What does insulator mean???
An insulator is an object that does not easily conduct electricity, not an object that "cannot conduct electricity". Because some insulators will also conduct electricity under special circumstances, such as dry wood is an insulator, and wet wood is a conductor; Air is normally an insulator, but at high voltage it conducts electricity and becomes a conductor.
What does insulator mean???
An insulator, also known as a dielectric, is a material that hinders the flow of electrical charge. In an insulator, valence band electrons are tightly bound around their atoms. This material is used as an insulator, or insulation, in electrical equipment.
Its function is to support or separate the individual conductors of the electric silver hand and prevent the current from flowing through.
Hope. What is the best insulator?
The insulating properties of ceramics are indeed one of the best insulator materials, and objects must not contain charged particles in order to insulate. Of course, there can be no absolutely insulated objects - at least not yet. But just finding an object that doesn't carry any electrons is one step closer to discovering a new insulator.
So for the time being, ceramics are the best insulators for the largest limbs.
What does insulator mean???
Insulator Definition:
Objects that do not easily conduct heat or electricity. There are two kinds of thermal and electrical insulators.
Insulators in Chinese.
Pinyin] [jué yuán tǐ].
What is an insulator?What does it mean to describe a girl?
It probably means that people are not popular, or life rarely touches the emotional aspects of men and women.
There are many reasons for this...
Maybe I didn't meet the right person.
Maybe it's because of their own lack of conditions.
Maybe it's because the character is not liked.
Maybe it's too closed to yourself.

Ask what is the explanation of the noun for balanced spacing.
Answer: The equilibrium distance refers to the spacing between molecules when the gravitational force and the repulsive force are equal, when the molecular spacing is smaller, the repulsion force is greater, when the spacing is larger, the gravitational force is the gravitational force, when the distance increases, the gravitational force increases first and then decreases, and when it reaches infinity, it is zero.
The gravitational force and the repulsive force between molecules always exist at the same time, and both decrease with the increase of the distance between molecules, but the law of decrease is different, and the repulsion force decreases rapidly.
When the intermolecular distance is equal to the equilibrium distance, the gravitational force is equal to the repulsion force, and the intermolecular force is zero, when the intermolecular distance is less than the equilibrium distance, the repulsion force and gravitational force increase with the decrease of the intermolecular distance, but the repulsion force increases rapidly, so it shows repulsion, when the intermolecular distance is greater than the equilibrium distance, the repulsion force and gravitational force decrease with the increase of the intermolecular distance, but the repulsion force decreases quickly, so it shows gravitational force.
In the diffusion movement, we will find that the higher the temperature, the faster the diffusion. When observing Brownian motion, it is also observed that the higher the temperature, the more pronounced the motion of suspended particles. These states of affairs suggest that the irregular movement of molecules is related to temperature, and the higher the temperature, the more intense this movement becomes.
Therefore, we call the irregular motion of molecules that never stops as thermal motion.
Question the definition of conductors.
A conductor is an object that conducts electricity easily, i.e., it is capable of passing an electric current through a material; Objects that do not easily conduct electricity are called insulators. There are freely moving electrons in a metal conductor, and the reason for conducting electricity is free electrons. The resistivity of semiconductors gradually decreases with temperature, and the conductivity is greatly improved, and the reason for conductivity is the holes and electron pairs in the semiconductor.
Ohms are commonly used in science and engineering to define the degree of electrical conductivity of a material.

Question 1: What objects are conductors? Which objects are insulators In physics, objects that easily conduct electricity are called conductors, and objects that do not conduct electricity easily are called insulators.
Various metals, graphite, human body, water containing impurities (such as sugar water, salt water), etc., belong to conductors.
Plastic, rubber, nylon, pure water, etc., belong to insulators.
Question 2: Which are the insulators and which are the conductors 1Conductor: Some objects are good at conducting electricity, which is called conductor.
For example: metals, human body, earth, graphite, acids, alkalis, salt water solutions, etc. are all conductors.
2.Insulator: Some objects are not good at electricity, called insulators.
For example: rubber, glass, plastic, ceramic, oil, pure water, dry paper, dry wooden sticks, dry air, etc. are all insulators.
I hope it helps you, and if you have any questions, you can ask them
I wish you progress in your studies and go to the next level! (*
Question 3: What is an insulator? It is a non-conductive object, such as wood, plastic, glass, rubber, etc.
Question 4: What are insulators Insulators: "pure substances" that do not easily conduct electricity
Conductor: A "pure substance" that is easy to touch
This refers to the usual state, for example, glass is an insulator at room temperature, but it is a conductor at high temperature.
Question 5: What is insulated in daily life? A lot, like plastic, rubber, wood, glass, stone, and so on, but it's all in the dry state, and there's distilled water.
Question 6: What is an insulator Definition of insulator: An object that does not easily conduct electricity is called an insulator.
This is the physical definition of the line of modern people say that they can't get over the electricity of others, that is, they have no feeling of liking, people who are not easy to like others, have no feeling for something or something, and are not interested. Rejecting all objects of fate, to put it seriously, not interested in the opposite sex, I feel that basically men and women are the same, there is no difference. Or rather, a tactful way of refusing

1. We are most likely to make the mistake, and the most important one of them, is to eat too much when eating. Sometimes there are too many foods, and we will think that our appetite is too small, but we are reluctant to give up the food and insist on eating it. Such a diet is very unhealthy, food blockage in the intestines will lead to indigestion, increase the burden on the stomach and intestines, may cause intestinal diseases, as well as blood flow, and may also cause heart disease. >>>More
