Alumina insulator uses
Alumina insulators are widely used in a variety of industries, especially in the electrical industry.
Electric power industry: Alumina insulators have good insulation properties and can be used as insulators for high-voltage transmission lines, substation equipment, cable joints, etc. They can ensure the safety of long-distance power transmission in high-voltage wires, and serve as transformers, Insulating components for equipment such as switch cabinets and circuit breakers.
Electronic industry: Alumina insulators can be seen in some semiconductors, electron tube devices, and integrated circuit substrates. Such as electron tube bases, alumina insulators can provide excellent insulation properties and stable thermal conductivity for vacuum electron tubes and microwave tubes. As a semiconductor device, it can provide excellent heat dissipation performance.
In addition, alumina insulators are also widely used in other industries, such as high-temperature components and insulation materials in the aviation industry, and insulation materials in microwave communication equipment. Alumina ceramic insulators can provide stable electrical performance and Very low losses.
Strong Strength
We have a professional high-grade ceramic production factory with more than 15 years of professional experience and numerous technical research results in high-grade ceramic production.
We produce high-quality products in a 10,000-level dust-free workshop, using the best alumina raw materials and advanced equipment to ensure the performance of subsequent ceramics.
During the molding process, we use various advanced equipment, such as injection molding machines, isostatic presses (CIP), hot presses, etc. The operation of these equipments and our professional staff guarantee the quality of alumina ceramic insulator products.
Sintering is a critical step in the ceramic manufacturing process. We use a rapid sintering furnace (RAPID) to ensure quality while greatly shortening the ceramic sintering cycle. We also have microwave sintering furnaces, hot isostatic pressing furnaces (HIP) and other equipment for sintering different alumina ceramics. Our professionals strictly and accurately control the sintering time and temperature of ceramics to further improve the performance of alumina ceramics.
We conduct strict product inspection on our products. For high-precision ceramic insulator parts, we achieve the smallest and most reasonable tolerances;
A group of R&D teams with rich professional knowledge are at your service at any time. We enjoy a good reputation at home and abroad and are appreciated by many partners.
pack
