The insulation paper for motor winding refers to the paper material used to wrap around the wire winding of the motor. In recent years, the energy industry has been facing the most difficult time.
The increasing demand for energy, coupled with an increase in the price of electricity, and the shortage of power supply, are affecting the growth of the electric industry. The problem is getting worse every day.
So what should be done? What kind of changes should be made to ensure the stable development of the electricity market?
That’s where insulation paper for motor winding comes into play. Here, we will talk about insulation paper for motor winding.
Insulation Paper for Motor Winding- How-To
Winding a motor is a difficult job. To start, you must cut through an insulating paper covering the windings. Then you must strip the wires, leaving a smooth copper layer.
The wires must be twisted together to form a coil. Next, you must solder these coils to a steel core. This core must be mounted to a motor shaft, then the whole thing must be wound with tape.
What is Insulation Paper?
Insulation paper is made of a mixture of synthetic resin fiber, plasticizer, and additives to make the resin flexible. This type of insulation is used in electric transformers.
The insulation paper should have the properties of insulation, flexibility, and resistance to oil-water and heat.
PVC Insulation Paper
PVC insulation paper is a common type of insulation paper for motor winding. It is usually made of PVC film and PVC sheet.
Typically, insulation paper is divided into two layers: an inner layer and an outermost layer. The inner layer is mainly composed of PVC film, and the outer layer is mainly composed of PVC sheets.
When the PVC insulation paper is in use, it is easy to remove. After being installed in the wire winding of the motor, the insulation paper is easily cut off if the motor is removed from the equipment.
In addition, the PVC insulation paper has good flame retardant and insulation performance and is easy to install. The main components of the insulation paper are PVC, polyester, glass fiber, mineral fiber, and the like.
Factors Affecting The Performance of The Insulation Paper
The most important factor is the PVC content. According to the specifications of the insulation paper, the content of PVC should be between 45% and 60%.
If the content of PVC is too high, it will affect the performance of the insulation paper and cause a large number of defects.
The material can also be used in the insulation of wires and cables for electric vehicles, power cables, wind turbines, transformers etc.
The insulation paper has excellent properties such as high heat resistance, low dielectric loss, good mechanical strength, low flammability, easy installation, and so on.
Also, it can be applied to the motor winding of electrical appliances such as air conditioners, refrigerators, washing machines, motor, etc. It is widely used in the field of motor winding.
Why is Insulation Paper Used?
Electrical insulation paper is used for many different reasons. The biggest reason is that electrical insulation paper prevents current from moving through an object and causes an electric shock. It also stops any electrical currents from spreading out into the atmosphere
Can Insulation Paper Withstand High Voltage?
Insulation paper for motor winding can withstand high voltage, but only if you choose the right kind. We’re talking about insulation paper for high-voltage motor windings.
Drawbacks of weak Insulation Paper
When the motor starts working, it generates static electricity. The charge will be discharged in the course of normal operation. If the insulation paper is not strong enough, the insulation layer will be damaged, resulting in electric shock or even an explosion.
In summary, insulation paper for motor winding is an effective, low-cost method for protecting electrical equipment.
