 Feature

Equalizing shielding ring Main Function:
1.The main function is to equalize the voltage. It is suitable for alternating voltage. 
It can evenly distribute the high voltage around the object, so as to ensure that there is no potential difference between various parts of the ring, so as to achieve the effect of equalizing the voltage.
2.In the design, two main reinforcements in the ring beam can be welded into a closed ring, which must be connected with all down conductors.

Equalizing shielding ring usage requirement: 
1.In the architectural design, when the height exceeds the radius of the rolling ball (30 meters for class I, 45 meters for class II and 60 meters for class III), a grading ring shall be set every 6 meters.
2.It is required to set a grading ring every 6m, so as to connect the metal doors and windows with the grading ring in the upper and lower layers within 6m height.
3.The grading rings used in high-voltage electrical appliances and power systems (substations, high-voltage lines, etc.) in China are mainly made of aluminum alloy.
