Good insulators provide protection against breakdown at the declared voltage level, which eliminates emergencies during equipment operation. They have found wide application in electrical engineering and are used massively in production. As for materials, ceramic insulators made of pure raw materials according to GOST standards are widely used today.
The mass use of ceramic insulators began in the 80s, they replaced ferrite: materials that were made on the basis of iron oxides. Such components began to be used for the manufacture of elements of complex circuits, in resistors and capacitors. They are used today, have good dielectric properties and even resistance to heat.
Properties of ceramic insulators
Ceramics are an excellent material for the production of insulators. Such components are made from crushed inorganic substances to a powder state, the raw materials are baked at high temperature, which provides excellent performance characteristics for the products. During production, the requirements of GOST are strictly observed, special attention is paid to such properties as porosity and the presence of a protective glossy coating.
Note the key features of ceramic insulators:
resistance to moisture;
high strength;
durability;
small dielectric losses;
resistance to aggressive substances;
resistance to heat.
Thanks to all these advantages, ceramic insulators are actively used in the electrical industry. Sometimes components work with temperature and humidity changes, as well as in aggressive environments.
