Our filter reactors are made of high-class transformer sheets and copper wire or aluminum band.They are dried and impregnated in vacuum with evironment friendly low-styrole resin which ensures they can withstand high voltages. have low noise levels, and offer a long operating life.Depending on their rated power, the reactors are provided with either terminal blocks or terminal lugs/cables.The connection of the aluminium reactors is made through copper terminals as well, which are reliably connected with the aluminium band by a special, well-proven welding method.
