ระยะห่างระหว่าง Busbar (Typical clearance for busbar)
The following table indicates the possible clearance reduction as a result of using Rasulate insulation. These spacing are derived from BIL, AC withstand, DC withstand, and discharge extinction tests on a limited number of busbar configurations insulated with Raysulate products. Due to the wide range of possible busbar geometries, these spacing should not be adopted withouttesting by user. Sharp electrodes and unusal geometries will require wider spacing.
