Insulation sleeve is a kind of mica insulation sheets, is a collectively. The insulation sleeve is made of high quality muscovite paper or phlogopite paper with high-performance organic silica gel bonded by the processing of the rigid tubular insulation material. Insulation casing (mica casing) has good electrical insulation performance and high mechanical strength, insulation casing (mica casing) cooperation in a variety of electrical appliances, electrical, electric smelting furnace and other equipment in the electrode rod or outlet mica casing insulation. Compared with the traditional ceramic tube, insulation casing (mica casing) with wall thickness and oval degree easy to control, discharge evenly, not broken, etc., polyimide glass fiber(mica casing) is the ideal alternative to some ceramic tube. Insulation sleeve (mica casing) is divided into hp5 mica tube temperature 500 ℃, hp8 gold mica tube temperature 800 ℃.

insulation cable paper has inherent dielectric strength, mechanical toughness, thermal stability, chemical compatibility, low temperature performance, is not sensitive to moisture, radiation resistance is the specific characteristics of insulating paper, and we in the future work or life You can use it, you can use it for dry-type transformer circuit breaker panel, spiral wound tube, capacitor insulation layer, DC coil insulation, current-carrying wire and devices, busbar insulation and other aspects, these aspects are Can be used very well, can make the insulating paper play a very good role.
Insulation paper, whether it is for us to work or life, then, is a very good thing, to our lives has brought a lot of help to improve our work efficiency

bakelite electrical insulation board, in recent years, made a special high temperature paper manufacturing breakthroughs, there are several enterprises producing insulating paper products, the temperature and pressure resistance, and the current foreign commonly used H-class insulation paper performance close to the insulation level are To 200, Mu H-class magnet wire requirements. At present, in a company's newly developed mine explosion-proof dry-type transformers, made a domestic insulation paper trial and verification.
In order to improve the production efficiency and working quality of insulating paper embedded in the rotor slot of the motor, it is necessary to conceive a high efficiency motor rotor embedded paper machine.
The working process of the rotor of the motor rotor
The g10 fiberglass sheet is fed to the working platform through the stick, the cutter moves down, cuts the insulating paper, and returns it. The insulating paper continues to move forward in the next cycle, the paper feed machine moves down and returns, The paper is sent to the tank, the motor rotor turns sixty degrees, pushing the paper machine down and pushing the paper into the slot

Explore the practicality of insulating material in electrical equipment

What are the applications of electrical insulating board in electrical equipment? In response to this question, we have to answer: In many electrical equipment, often use insulating materials to other sports materials to isolate. Often we see solid insulation materials: insulating paper, laminates, rubber, plastic, paint, glass, ceramics, mica, etc., in a variety of industrial production often use such solid insulation materials. As the insulation material on the DC current has a very large resistance, under the action of DC voltage, in its surface almost no current through, play a very good insulation.
We all know that in the production of many electrical equipment, the more involved in the line, so often need to use insulating materials. General electrical appliances are made of conductive materials, magnetic materials, insulating materials and epoxy glass laminate sheet, etc., in addition to insulating materials, the rest of the material is mostly metal materials. In the motor electrical operation, it is inevitable to be temperature, electricity, mechanical stress and vibration, harmful gases, chemicals, moisture, dust and radiation and other factors. Compared to other parts of the material, the sensitivity of the insulation material is stronger. If the impact of these factors, insulation materials will deteriorate and so on, so that we can early detection of problems, and timely processing.

The role of insulating material

Insulation material is one of the key factors to determine the technical and economic indicators of electrical and electrical appliances. In the electrical equipment, the charged parts are separated from each other. Therefore, the insulating material should first have high insulation resistance and compressive strength and can avoid the occurrence of Leakage, breakdown and other accidents. Second, the heat resistance is better, to avoid long-term overheating and aging deterioration; In addition, there should be good thermal conductivity, resistance to lightning and high mechanical strength and process processing and other characteristics.
An unsaturated polyester glass mat sheet used to isolate conductive parts of different potentials. Its conductivity is about 10-10 West / m below. Different electrical products, according to the needs of insulating materials are often also play energy storage, cooling, cooling, arc, moisture, mildew, anti-corrosion, radiation protection, mechanical support and fixed, protective conductor and so on.

The properties of the insulating material are affected by which composition

We can not leave acetate cloth tapes in our lives, insulation materials in the harmful gases and wet dust and other conditions will be affected? Let's talk about the knowledge of insulating materials.
1. Resistance, resistivity:
   Resistance is the reciprocal of conductance, the smaller the conductive material, the greater the resistance, the higher the resistivity the better.
2. Sealing degree:
   On the oil, water quality seal cut off better.
3. Ignition resistance:
   People on the insulation of the fire resistance requirements are getting higher and higher, the higher the fire resistance, the better the security,
4. Resistance to arc:
   Insulation material of the surface composition of the electrical layer to determine the insulation of the arc-shaped material. The greater the time value, the better the arc resistance.
5. Tensile strength:
   Insulation material mechanics of the tensile strength of the most extensive, the most representative of the implementation.
6. Voltage, electrical strength:
   Insulation material breakdown voltage, the higher the electrical strength the better.

Insulation board to protect the safety of electricians

electrical insulating board is used in substations, power plants, power distribution rooms, laboratories and field live operations, because it has a high insulation, it can be 35KV and below the live part of the direct contact, from the temporary cover effect, This will allow the electrical safety of individuals to be protected.
Why can the insulation plate have such a good effect? Because the insulation plate has high mechanical strength, dielectric properties, oil resistance and corrosion resistance of the function, so to play the role of insulation. Insulation board and other board is not the same, the appearance of the surface should be smooth and smooth, do not allow impurities and other obvious defects, allowing a slight scratches, the edge should be cut neat, the end surface must not have layers and cracks. At the same time insulation board is also suitable for high-performance electronic insulation requirements of the product.
In addition, the insulation plate in the form of many kinds of strong adhesion, which helps to bond, chemical stability is also very stable, so durable, and resistant to mold, so do not worry about the placement of a long time, And the effect of the effect.
