Ceramic insulators

Electrical insulators: In electrical engineering, ceramic insulators are essential for isolating and protecting electrical circuits from unwanted current transfer. These insulators are widely used in power transmission lines, transformers, electric generators and high-voltage circuits. The advantages of technical ceramics as an electrical insulator include its high dielectric strength and chemical stability. They are able to withstand high voltages and prevent electrical leakage.

Thermal insulators: Ceramic materials are known for their excellent thermal insulation ability. In heating processes and furnace technology, they are used as insulators to minimize heat loss and direct heat energy to the desired areas. They are also used as heat shields in spacecraft and satellites to protect against extreme temperatures in the space environment.

High-voltage industrial plants use 95% Al2O3 ceramic insulators that:
exhibits high electrical resistance of 20 kV/mm. In addition to insulators, this ceramics is also used for elements that have good thermal conductivity, usually in electrically powered high-temperature systems.
The same material is used for the manufacture of resistors to be mounted in high-voltage power plants.

Due to its excellent mechanical properties even at elevated temperatures, this ceramics is most often used for insulators in the electrical industry, heat insulators for various heating systems, spark plug insulators for engine ignition systems, etc.

Advantages of technical ceramic insulators:

1. High temperature resistance:
   Ceramic insulators can withstand extremely high temperatures without losing their insulating properties. This makes them ideal for use in hot and demanding environments.
2. Durability:
   Technical ceramics is known for its durability and resistance to wear and corrosion. They have a long service life and require minimal maintenance.
3. Chemical stability:
   Ceramic insulators are resistant to chemicals and corrosion, making them suitable for use in aggressive environments.
4. Dielectric strength:
   They have a high dielectric strength, which is crucial to prevent electrical charges from flowing through the insulator.
5. Adaptability:
   Technical ceramics can be shaped and customized to meet specific requirements and geometries, making them versatile and useful in various applications.

In summary, technical ceramics are crucial as insulators in a variety of technical fields. Their ability to insulate and protect against electric current and heat has a significant impact on the safety, performance and durability of various industries and technological applications.
