Features

1. Advanced glass-metal hot sealing technology: linear expansion coefficient of borosilicate glass and sealing alloys is similar which can realize glass-metal sealing. It solves the mismatch of linear expansion coefficient between glass and metal.

2. Selective absorbing coating can withstand high temperature from 400 ºC to 500 ºC in a high vacuum condition, to ensure that the sunlight selective absorption coating can keep long-term stability of absorption ratio at high operating temperature.

3. All parts of the vacuum tube pass high temperature and high vacuum exhaust and the tube has a long-acting getter, ensuring it can maintain a high degree of vacuum during its using process.

4.
Paten-designed elastic sealing components and sealing protection devices, ensuring stable and reliable sealing.

5. It ends are plug structure made by precision turning, easy to install and weld and ensuring the straightness of the system.
