The description of steatite ceramic insulator
Steatite Ceramic usually called high-frequency ceramic, which is the most common ceramic material. Steatite Ceramic is a low-cost material with high electrical resistance at high temperatures, good mechanical strength, and a very low dielectric loss factor.
Such properties make Steatite Ceramic Insulators ideal for high frequency, low loss, and high voltage insulation. Moreover, Steatite Ceramic can be readily shaped and sintered into a wide variety of forms such as washers, bushings, resistor forms, spaces, and blocks. So, Steatite Ceramic Insulators is an excellent material for electrical engineering.
The application of steatite ceramic parts
Steatite ceramic insulators have been used for many years in large-scale industrial systems, household electronic appliances, aerospace, and automotive applications, and specialized electro-technical instruments such as cathode-ray tubes, Ceramic Band Heater Insulators, Heating element holders, Standoff Insulators, Interlocking Insulating Beads, Split bush insulators, Lamp bases and caps, Spacers, Insulating washers or bushings
Remark:
Alumina ceramic parts are widely used in electronic, electrical, machinery, chemistry, ceramic seals, minerals, new energy, military, aerospace, and almost all modern industries.
