Insulation Auxiliary Materials

Insulation Auxiliary Materials, or Insulation Auxiliary Materials, are an indispensable part of the electrical industry. They work together with insulation materials to ensure the normal operation and safety performance of electrical equipment. The following is a detailed introduction to Insulation Auxiliary Materials:

1. Definition and classification

Insulation Auxiliary Materials refer to various materials used to enhance, protect or improve the performance of insulation materials. They are usually used in the manufacture, maintenance and upgrading of electrical equipment to improve the insulation level, heat resistance, corrosion resistance and service life of the equipment. According to different functions and uses, Insulation Auxiliary Materials can be divided into many types, such as insulation paint, insulation glue, insulation oil, insulation cloth, insulation paper, etc.

2. Main functions

Enhance insulation performance: Insulation Auxiliary Materials can fill the gaps between insulation materials, improve the overall insulation resistance and dielectric strength, thereby ensuring that electrical equipment works normally under the specified voltage.

Improve heat resistance: Some Insulation Auxiliary Materials have high heat resistance, can maintain stable insulation performance in high temperature environment, and prevent insulation failure caused by temperature changes.

Corrosion resistance: Insulation Auxiliary Materials usually have a certain corrosion resistance, can resist the erosion of chemical substances, and protect insulation materials from damage.

Protecting insulating materials: Through coating, wrapping and other methods, insulating auxiliary materials can provide additional protection for insulating materials to prevent them from being adversely affected by mechanical damage, moisture erosion and other adverse effects.

3. Commonly used materials

Insulating varnish: Insulating varnish is a commonly used insulating auxiliary material with good insulation and heat resistance. It can be applied to electrical equipment by impregnation, coating and other methods to improve the insulation level of the equipment.

Insulating glue: Insulating glue is mainly used to fill the gaps between insulating materials to improve the overall insulation performance. At the same time, it can also provide additional mechanical strength and sealing performance.

Insulating oil: Insulating oil is mainly used for insulation and cooling of electrical equipment such as transformers. It has good insulation performance and thermal stability, which can ensure the normal operation of equipment in high temperature environments.

Insulating cloth and insulating paper: These materials are mainly used for wrapping and isolation of electrical equipment to prevent current from passing directly or causing short circuits. They usually have high insulation resistance and dielectric strength.

4. Application and selection

Insulating auxiliary materials are widely used in electrical equipment, including generators, transformers, switchgear, cables, etc. When selecting insulating auxiliary materials, the following factors need to be considered:

Electrical performance: Select materials with appropriate insulation resistance and dielectric strength according to the rated voltage and current of the equipment.

Heat resistance: Select materials with appropriate heat resistance according to the operating temperature and thermal stability requirements of the equipment.

Mechanical properties: Select materials with sufficient mechanical strength and toughness according to the mechanical stress and vibration of the equipment.

Corrosion resistance: Select materials with corrosion resistance according to the environmental conditions of the equipment.

5. Development trend

With the continuous development and progress of electrical technology, insulating auxiliary materials are also constantly innovating and improving. Insulating auxiliary materials in the future will be more environmentally friendly, efficient and intelligent to meet the requirements of electrical equipment for higher performance and reliability.
