- Core Performance Advantages
- Outstanding insulation performance: It has a volume resistivity of over 1×10¹³Ω·cm at 100℃, and its DC breakdown strength can reach 30 - 40KV/mm. This excellent insulation property can effectively prevent leakage risks when the lamp socket is in contact with current during operation, which is especially crucial for high - voltage lighting equipment.
- Strong high - temperature resistance: Its maximum service temperature can reach 1650℃. Even when high - power lamps emit a large amount of heat during long - term operation, the socket will not deform, soften, or lose its performance. Moreover, it has good thermal shock resistance. After being kept at 800℃ for 30 minutes and cooled to room temperature repeatedly for 10 times, there will be no cracks or bursts.
- Excellent mechanical and corrosion resistance: It has a compressive strength of 2100MPa and a flexural strength of not less than 280MPa. It also has a Mohs hardness of 9.0, so it is wear - resistant and not easy to be damaged during installation and use. In addition, it can resist the erosion of strong acids and alkalis. It will not be corroded even when immersed in 10% hydrochloric acid or sodium hydroxide solution at 100℃ for 1 hour, which extends its service life in harsh environments.
- Stable dimensional stability: The 95% alumina ceramic has a low linear expansion coefficient. When the temperature is between 20 - 800℃, the coefficient is only 6.5×10⁻⁶ - 8×10⁻⁶/℃. This ensures that the socket will not have obvious dimensional changes due to temperature fluctuations, so as to maintain a stable fit with the lamp.
