First, the advantages of the insulator
1. Good insulation
The insulator has excellent insulation performance and can effectively isolate the electric field between the conductor and the grounding body to ensure the normal operation and electrical safety of the power equipment. Especially in recent years, with the improvement of voltage levels, more high-performance insulators are needed, and the use of insulators has become more extensive.
2.Long service life
Insulator materials are usually high-strength ceramic materials, silicone materials, glass fiber reinforced plastics, etc., the service life is much longer than traditional metal materials, and can maintain good insulation performance for a long time.
3. Good heat resistance
Insulators can adapt to high temperature environment, maintain good insulation performance, but also can withstand the intrusion of high voltage, electric field and strong current, so it is widely used in high-voltage power equipment.
4. High cost recovery
Although the price of the insulator is higher, its service life is also longer, and it does not require maintenance during use, so its cost recovery rate is high, which can reduce the cost of use of users.
1.Insulation protection
Insulator is an important insulation protection device, which can effectively isolate power equipment and lines, prevent current leakage and short circuit accidents, and ensure the safe operation of the power supply system.
2. The support line
Insulators are also often used to support transmission, power transformation, distribution lines, as an insulation device installed in the power pole, cable trough, can isolate the power line from the tower, ground, building, to ensure the safe operation of the line.
3. Adjust the voltage
Insulators can also be used to regulate voltage. The use of high-voltage power equipment must have appropriate insulation protection to ensure the normal operation of the equipment. The use of insulators can realize the insulation protection of power equipment and the uniform distribution of electric field, so as to stabilize the voltage and ensure the safety and reliability of power equipment.
4. Other uses
In addition to being used in the field of power, insulators are also suitable for construction, machinery, chemical and other fields. For example, in the field of construction, the use of insulators can effectively isolate steel bars and concrete, improve the performance of concrete, and prevent problems such as rust of steel bars and cracks of concrete. In the chemical industry, the use of insulators can isolate the electric field between liquids and solids and prevent the occurrence of electrolytic reactions.
