What is equalizing ring? Why do uPVC windows in high-rise buildings need equalizing rings?

Pressure equalization ring: The main function is to equalize the voltage. It is suitable for AC voltage. It can evenly distribute the high voltage around the object to ensure that there is no potential difference between the various parts of the ring, so as to achieve the effect of equalization.

The uPVC Window of high-rise building must be made of equalizing ring. Because the main function of the equalizing ring is to equalize the voltage, it is suitable for AC voltage, which can evenly distribute the high voltage around the object to ensure that there is no potential difference between the various parts of the ring, so as to achieve the effect of equalizing the voltage. In architectural design, when the height exceeds the radius of the rolling ball (30 meters for the first type, 45 meters for the second type, and 60 meters for the third type), an equalizing ring is set every 6 meters. In the design, the equalizing ring can be welded into a closed ring by using the two main ribs in the ring beam, and this closed ring must be connected with all the down conductors. It is required to install a pressure equalizing ring every 6 meters, the purpose of which is to facilitate the connection of the metal doors, windows and the pressure equalizing ring on the upper and lower floors within a height of 6 meters.
