Oil-immersed vacuum type on-load tap-changer


The switch for AC 10kV, 50Hz or 60Hz, the highest voltage equipment 12KV and below, rated current 200A and below the three-phase oil-immersed transformers.
The switch uses vacuum tubes to replace the traditional copper-tungsten alloy to convert the load current, so to solve the switching frequency, arcing contact burn, charring issue insulating oil to improve the mechanical and electrical life. Extend the maintenance cycle, reducing maintenance costs.
