Description

Technical Field

When the heights of the conductive heads are inconsistent, a gap will appear between the lower conductive head and the sled bowl. When power is on, this gap will generate sparks, leading to risks such as burning of the conductive head and breakdown of the sled bowl; the sled and the vehicle body run in the electrophoretic fluid, and will float when impacted by the electrophoretic fluid.
